RESUMO
La hidradenitis supurativa (HS) es una enfermedad inflamatoria crónica de la piel que afecta a las glándulas sudoríparas apocrinas y causa nódulos inflamatorios, abscesos y fistulas dolorosas en áreas como las axilas, la ingle y los glúteos. Su impacto en la calidad de vida de los pacientes es significativo. La HS afecta al 1- 4% de la población mundial y se asocia con factores como el sobrepeso, el tabaquismo y antecedentes familiares. Su patogenia es compleja, involucrando inflamación y disfunción inmunológica. Su diagnóstico y tratamiento son desafiantes, especialmente en casos graves. El diagnóstico se basa en la presentación clínica, que a menudo se confunde con otras afecciones cutáneas. Se clasifica en etapas de Hurley según la gravedad. El tratamiento se centra en controlar los síntomas y prevenir recurrencias. Incluye educación del paciente, tratamiento médico y cirugía. La elección de la terapia antibiótica depende de la severidad y las cepas bacterianas presentes. Para casos graves, se investigan terapias biológicas. La cirugía, como la escisión simple o con injertos de piel, es efectiva en el control de la enfermedad. Presentamos un caso clínico de un paciente con HS, revisamos la epidemiología, etiopatogenia y su diagnóstico acompañado de las opciones terapéuticas existentes

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the apocrine sweat glands and causes inflammatory nodules, abscesses, and painful fistulas in areas such as the armpits, groin, and buttocks. Its impact on patients' quality of life is significant. HS affects 1-4% of the world's population and is associated with factors such as overweight, smoking, and family history. Its pathogenesis is complex, involving inflammation and immune dysfunction. Its diagnosis and treatment are challenging, especially in severe cases. Diagnosis is based on clinical presentation, which is often confused with other skin conditions. It is classified into Hurley stages based on severity. Treatment focuses on controlling symptoms and preventing recurrences. Includes patient education, medical treatment and surgery. The choice of antibiotic therapy depends on the severity and the bacterial strains present. For severe cases, biological therapies are investigated. Surgery, such as simple excision or skin grafts, is effective in controlling the disease. We present a clinical case of a patient with HS, we review the epidemiology, etiopathogenesis and its diagnosis accompanied by the existing therapeutic options.

BACKGROUND: The Parks classification has been used for the classification of anal fistula for several years, but it does not allow for risk factors for failure after surgery. OBJECTIVE: This study aimed to describe a modification of the Parks classification of anal fistula and examine its predictive validity in the assessment of the outcome of anal fistula in terms of failure of healing and fecal incontinence. DESIGN: This is a retrospective review of a prospective database. SETTING: This study was conducted in the Colorectal Surgery Unit, Mansoura University Hospitals. PATIENTS: Adult patients with anal fistula who underwent surgery were included. INTERVENTIONS: Five risk factors for failure after fistula surgery were identified from the literature and were examined by multivariate analysis of our patients. Four risk factors proved to be significant independent predictors of failure: secondary extensions, horseshoe fistula, previous fistula surgery, and anterior anal fistula in women. We modified the Parks classification by dividing the transsphincteric type into high and low and by grouping supra- and extrasphincteric anal fistulas into 1 group. The first 3 stages were subdivided according to the absence or presence of predictors of failure. MAIN OUTCOME MEASURES: The primary outcome measured was the validity of the modified Parks classification with regard to the rates of failure and fecal incontinence after surgical treatment of each stage of anal fistula. RESULTS: A total of 665 patients with cryptoglandular anal fistula were included. Failure rates increased from 2.3% (95% CI, 0.9%-4.7%), to 17.4% (95% CI, 10.8%-25.9%), 19.5% (95% CI, 15%-24.6%), and 30.7% (95% CI, 9.1%-61.4%) across the 4 stages. The area under the receiver operating characteristic curve was 0.90 (95% CI, 0.85-0.94) indicating the strong discriminative ability of the final multivariable predictive model. The increase in failure and incontinence rates across the fistula stages was significant. LIMITATIONS: This is a retrospective, single-center study. CONCLUSION: Inclusion of predictors of poor outcome into the modified classification helped differentiate simple and complex fistulas within each stage and between the different stages, which can help in assessment and decision making for anal fistula.

MODIFICACIN DE LA CLASIFICACIN DE PARKS DE LA FSTULA ANAL CRIPTOGLANDULAR: ANTECEDENTES:La clasificación de Parks se ha utilizado para la clasificación de la fístula anal durante varios años, sin embargo, no tuvo en cuenta los factores de riesgo de fracaso después de la cirugía.OBJETIVO:Describir una modificación de la clasificación de Parks de fístula anal y examinar su validez predictiva en la evaluación de los resultados de la fístula anal en términos de fracaso de la cicatrización e incontinencia fecal.DISEÑO:Revisión retrospectiva de la base de datos prospectiva.AJUSTE:Unidad de Cirugía Colorrectal, Hospital Universitario de Mansoura.PACIENTES:Pacientes adultos con fístula anal intervenidos quirúgicamente.INTERVENCIONES:Se identificaron cinco factores de riesgo de fracaso después de la cirugía de fístula de la literatura y se examinaron mediante análisis multivariante de nuestros pacientes. Cuatro factores de riesgo demostraron ser importantes predictores independientes de fracaso: extensiones secundarias, fístula en herradura, cirugía de fístula previa y fístula anal anterior en mujeres. Modificamos la clasificación de Parks dividiendo el tipo transesfinteriano en alto y bajo y agrupando la fístula anal supraesfinteriana y extraesfinteriana en un grupo. Las tres primeras etapas se subdividieron según la ausencia o presencia de predictores de fracaso.PRINCIPALES MEDIDAS DE RESULTADO:Validez de la clasificación de Parks modificada con respecto a las tasas de fracaso e incontinencia fecal después del tratamiento quirúrgico de cada etapa de la fístula anal.RESULTADOS:Se incluyeron 665 pacientes con fístula anal criptoglandular. Las tasas de fracaso aumentaron del 2,3% (IC del 95%: 0,9-4,7%), al 17,4% (IC del 95%: 10,8 al 25,9%), 19,5% (IC del 95%: 15-24,6%) y 30,7% (95% IC: 9,1- 61,4%) en las cuatro etapas. El área bajo la curva característica operativa del receptor fue 0,90 (IC del 95%: 0,85-0,94), lo que indica una fuerte capacidad discriminativa del modelo predictivo multivariable final. El aumento en las tasas de fracaso e incontinencia en las etapas de la fístula fue significativo.LIMITACIONES:Estudio retrospectivo, unicéntrico.CONCLUSIÓN:La inclusión de predictores de mal resultado en la clasificación modificada ayudó a diferenciar las fístulas simples y complejas dentro de cada etapa y entre las diferentes etapas, lo que puede ayudar en la evaluación y toma de decisiones para la fístula anal.

BACKGROUND: The management of Crohn's disease patients with perianal lesions and anti-TNF failure is challenging. AIMS: To assess the effectiveness of vedolizumab in perianal Crohn's disease and the predictors of success in a real-life cohort. METHODS: We conducted a nationwide multicentre cohort study in patients with perianal Crohn's disease who received vedolizumab. In patients with active perianal Crohn's disease, the success of vedolizumab was defined by clinical success (no draining fistula at clinical examination and no anal ulcers for primary lesions) at 6 months without medical or surgical treatment for perianal Crohn's disease. Logistic regression analyses were performed to identify predictors of success. In patients with inactive perianal Crohn's disease, recurrence was defined by the occurrence of lesions and/or the need for medical or surgical treatments. RESULTS: One hundred and fifty-one patients were included. Among them 102 patients had active perianal disease, 33 (32.4%) males, mean age 39.8 years, mean Crohn's disease duration 14.6 years; 101 (99%) had received at least one anti-TNF. The median follow-up time was 52 weeks. Sixty-eight per cent of patients discontinued therapy after a median time of 33 weeks. Vedolizumab success was reached in 23/102 (22.5%). Among patients with setons at initiation, 9/61(15%) had a successful removal. In multivariable analysis, factors associated with success were the number of prior biologic agents (≥3, odds ratio, OR: 0.20, 95% CI 0.04-0.98) and no antibiotics at initiation (OR: 4.76, 95% CI 1.25-18.19). In 49 patients with inactive perianal Crohn's disease, perianal disease recurred in 15/49 (30.6%), 11/49 (22.4%) needed dedicated treatments. Median time to recurrence was 22 weeks. CONCLUSIONS: We identified a low rate of success of vedolizumab in patients with active perianal Crohn's disease, and nearly one third of patients with inactive perianal Crohn's disease had perianal recurrence. Further evaluation is warranted in prospective studies.

Adipose mesenchymal stem cells (ASC) are considered minimally immunogenic. This is due to the low expression of human leukocyte antigens I (HLA-I), lack of HLA-II expression and low expression of co-stimulatory molecules such as CD40 and CD80. The low rate of observed immunological rejection as well as the immunomodulatory qualities, position ASC as a promising cell-based therapy for the treatment of a variety of inflammatory indications. Yet, few studies have addressed relevant aspects of immunogenicity such as ASC donor-to-patient HLA histocompatibility or assessment of immune response triggered by ASC administration, particularly in the cases of presensitization. The present study aims to assess allo-immune responses in a cohort of Crohn's disease patients administered with allogeneic ASC (darvadstrocel formerly Cx601) for the treatment of complex perianal fistulas. We identified donor-specific antibodies (DSA) generation in a proportion of patients and observed that patients showing preexisting immunity were prone to generating DSA after allogeneic therapy. Noteworthy, naïve patients generating DSA at week 12 (W12) showed a significant reduction in DSA titer at week 52 (W52), whereas DSA titer was reduced in pre-sensitized patients only with no specificities against the donor administered. Remarkably, we did not observe any correlation of DSA generation with ASC therapeutic efficacy. In vitro complement-dependent cytotoxicity (CDC) studies have revealed limited cytotoxic levels based upon HLA-I expression and binding capacity even in pro-inflammatory conditions. We sought to identify CDC coping mechanisms contributing to the limited cytotoxic killing observed in ASC in vitro. We found that ASC express membrane-bound complement regulatory proteins (mCRPs) CD55, CD46, and CD59 at basal levels, with CD46 more actively expressed in pro-inflammatory conditions. We demonstrated that CD46 is a main driver of CDC signaling; its depletion significantly enhances sensitivity of ASC to CDC. In summary, despite relatively high clearance, DSA generation may represent a major challenge for allogeneic cell therapy management. Sensitization may be a significant concern when evaluating re-treatment or multi-donor trials. It is still unknown whether DSA generation could potentially be the consequence of donor-to-patient interaction and, therefore, subsequently link to efficacy or biological activity. Lastly, we propose that CDC modulators such as CD46 could be used to ultimately link CDC specificity with allogeneic cell therapy efficacy.

BACKGROUND: Perianal complications in patients with Crohn's disease are common and have a negative impact on the patients' quality of life. Data about the long-term disease course of perianal Crohn's disease in the era of biological treatment are limited. In this population-based cohort study, we sought to investigate the occurrence, clinical risk factors, and disease course of perianal disease. METHODS: A total of 213 Crohn's disease patients were included in a prospective population-based inception cohort. Data were retrieved from medical records and national health administrative databases. Perianal disease was defined as a perianal fistula and/or abscess. Associations between outcomes and covariates were analyzed by Cox regression analysis. RESULTS: A total of 48 (22.5%) patients developed perianal disease after 10 years. Colonic disease location (hazard ratio [HR], 1.99; 95% confidence interval [CI], 1.01-3.92) and penetrating behavior (HR, 5.65; 95% CI, 2.65-12.03) were associated with the development of perianal disease. The cumulative risk of undergoing abdominal surgery was 51% after 10 years. Patients with perianal disease had a higher rate of resection (HR, 3.92; 95% CI, 1.86-8.67) and hospitalization (HR, 1.01; 95% CI, 1.00-1.01). There was no significant difference in the rate of sick leave, unemployment, or disability pension between patients with and without perianal disease. CONCLUSIONS: Patients with perianal disease carry a higher risk of surgery and hospitalization, and this suggests a more severe disease course and poorer prognosis among these patients, even in the era of biological treatment. These findings underline the importance of optimizing treatment strategies for patients with perianal disease.

BACKGROUND: Perianal (hepatoid) gland tumors are common in dogs, and the distinction between the benign and malignant forms is clinically important. Cytology of these tumors typically contains many large hepatoid cells and fewer small basal cells. OBJECTIVES: The objective of this study was to determine whether the proportion of the smaller basaloid reserve cells in cytologic samples from perianal tumors correlates with malignancy. METHODS: Eighty-three cases of cytologically diagnosed perianal gland tumors with corresponding histopathologic sections were identified from two separate institutions and included six (7.2%) malignant tumors and 77 (92.8%) benign tumors. The proportion of basal cells from each sample was evaluated. RESULTS: No difference between these groups was found, although the study was sufficiently powered to detect an approximately 1.5-fold change in basal cell proportion. CONCLUSIONS: This report found no evidence that the proportion of basal cells in canine perianal tumor cytology is an indication of the potential for malignancy. We, therefore, do not recommend citing this feature in cytologic reports or when communicating with clinicians.

Fine-needle aspirates from a perianal mass on an 8-year-old, intact male, Miniature Poodle presenting for tenesmus showed a uniform population of well-differentiated hepatoid cells with no notable criteria of malignancy. The cytologic diagnosis was a perianal gland tumor, with adenoma likely given the cytomorphology. The abdominal ultrasound revealed multiple, markedly enlarged, intra-abdominal lymph nodes. LN aspirates also showed well-differentiated polygonal, hepatoid cells displaying no notable cellular atypia. The presence of the metastasis led to the interpretation of a well-differentiated, malignant perianal gland tumor despite the benign cellular appearance. Histopathology of the surgically excised perianal mass and one enlarged abdominal lymph node revealed lobules of uniform polygonal hepatoid cells arranged in organized islands and trabeculae surrounded by a single layer of uniform reserve cells. Few mitotic figures were present. The only histopathologic indication of malignancy within the primary mass was the presence of small islands of well-differentiated hepatoid cells infiltrating into adjacent tissue and possible lymphatic invasion. The histopathologic diagnosis was perianal gland adenocarcinoma. Most textbooks describe perianal gland adenocarcinomas as showing increased cellular atypia including pleomorphism, disorganization of hepatoid cells, and increased numbers of pleomorphic reserve cells with mitotic figures. This case is an example of the occurrence of a well-differentiated perianal gland tumor with metastasis and highlights the importance of realizing that with these tumors, a benign cytologic and histologic appearance may not correlate with biologic behavior. To the authors' knowledge, this is the first case reporting both the cytologic and histologic appearance of a well-differentiated metastatic hepatoid gland tumor.

INTRODUCTION: Crohn's disease (CD) is a chronic, recurring, idiopathic disease which is associated with imbalanced mucosal immune response, manifesting as a chronic inflammation of any location throughout the gastrointestinal tract. The purpose of currently available therapy is to suppress the heightened immune response. However, these treatments have no direct influence on the healing process of damaged tissues. The mesenchymal stem cell (MSC) therapy may represent a new alternative solution in both luminal and fistulizing CD, as it is able to inhibit the inflammation and promote the regeneration process at the same time. AREAS COVERED: Aim of this review is to summarize the existing clinical data about the clinical impact of MSC therapy in luminal and perianal fistulizing CD. EXPERT OPINION: Clinical trials demonstrated that MSC transplantation has an outstanding, durable efficacy with low fistula recurrence in biological therapy-refractory fistulizing CD; however, further clinical trials are required to confirm its effectiveness in luminal CD. Unlike to biological therapy, MSCs are able to promote the regeneration process of damaged tissues as well. This additional benefit besides their sustained immunosuppressive effect with no decrease of efficiency over time makes MSCs a new, highly potential therapeutic approach in the management of inflammatory bowel disease.

Background: The differentiation between intestinal tuberculosis (ITB) and Crohn's disease (CD) is a challenge. The aim of this study was to investigate a predictive model for differential diagnosis between ITB and CD. Methods: A total of 268 patients who were suspected of having ITB or CD were prospectively recruited between January 2013 and September 2016. The clinical, laboratory, radiological, endoscopic, and histological features were investigated and subjected to univariate and multivariate analyses. The final predictive model was developed based on the regression coefficients of multivariate logistic regression. To validate the model, the same regression equation was tested on the other group. Results: A total of 239 patients had a final diagnosis, including 86 ITB and 153 CD. Five variables (perianal disease, pulmonary involvement, longitudinal ulcer, left colon, and ratio of tuberculosis-specific antigen to phytohaemagglutinin) were selected for the predictive model to discriminate between ITB and CD. In the predictive model of the training data set, the area under the receiver operating characteristic (ROC) curve, sensitivity, specificity, and accuracy, with a cutoff level of 0.29, were 0.975 (95% confidence interval [CI], 0.939-0.993), 96.7%, 90.7%, and 92.8%, respectively. Application of the predictive model to the validation data set showed similar performance in distinguishing ITB from CD. The area under the ROC curve, sensitivity, specificity, and accuracy were 0.950 (95% CI, 0.871-0.987), 88.5%, 93.5%, and 91.7%, respectively. Conclusions: This 5-marker predictive model could be conveniently used by clinicians to draw a reliable differential diagnosis between ITB and CD in clinical practice. 10.1093/ibd/izy154_video1izy154.video15790725497001.

BACKGROUND: Patient reported outcomes regarding perianal disease and faecal incontinence in the community-based inflammatory bowel disease population are poorly described. AIMS: To determine the impacts of perianal disease and faecal incontinence on quality of life and employment in inflammatory bowel disease patients. METHODS: For this cross-sectional study, a comprehensive survey was sent out to members of the Dutch National Crohn's and Colitis patient organisation. Validated questionnaires regarding faecal incontinence and active perianal disease were used to estimate its prevalence's. The effect on the quality of life (36-Item Short Form Survey) and on employment status (multivariate binary regression analysis) was assessed in this inflammatory bowel disease population. RESULTS: A total number of 1092 returned questionnaires (58% responders) were used for analysis; 750 respondents (69%) were female; mean age was 47 years (IQR 35-59). In 621 patients (57%) Crohn's disease, in 422 (39%) ulcerative colitis and in 49 (4%) patients unclassifiable inflammatory bowel disease was self-reported. The 114 patients (10%) with a stoma were excluded for continence related analyses. Faecal incontinence was reported in 555 patients (57%), was comparable between the different inflammatory bowel disease diagnoses and affected all 36-Item Short Form Survey subscales adversely (incontinence vs continence: Physical functioning 75 vs 84, P < 0.0001; Limitations due to physical health 49 vs 63, P < 0.0001; Limitations due to emotional problems 49 vs 64, P < 0.0001; Energy/fatigue 47 vs 53, P < 0.0001; Emotional well-being 71 vs 74, P = 0.005; Social functioning 63 vs 73, P < 0.0001; Pain 66 vs 75, P < 0.0001; General health 41 vs 48, P < 0.0001). Active perianal disease was reported in 39% Crohn's disease, 16% ulcerative colitis (84% fissures) and 20% unclassifiable inflammatory bowel disease patients. Faecal incontinence was more common in patients with perianal disease (67% vs 53%, P = 0.003). When correcting for age, disease duration, inflammatory bowel disease-related surgery and faecal incontinence, active perianal disease was independently affecting employment (OR 0.67; 95% CI 0.50-0.91; P = 0.01). CONCLUSIONS: Faecal incontinence and perianal disease are quality of life determining factors. Faecal incontinence needs more attention among clinicians, and development of new (drug) therapies needs to be focussed on perianal disease.

Patients with inflammatory bowel disease (IBD), particularly those on immunosuppressive medications, suffer a high incidence of, and worse clinical outcomes relating to, herpes zoster (HZ) reactivation. We report on the presentation and management of a patient with Crohn's disease who developed severe perianal HZ after starting azathioprine and oral budesonide treatment. The zoster vaccine may prevent such zoster reactivation in patients with IBD. The zoster vaccine is effective in decreasing the risk of HZ in older adults but its role in younger adults and those with IBD has not been tested prospectively. A review of the potential risks and benefits of this live vaccine in patients with IBD and an approach to further determining its role in this patient population is discussed.

Circumanal gland tumors are very common neoplasms of dogs. Their classification relies on microscopic examination and is further supported by a few immunohistochemical markers that help indicate their prognosis. However, new additional tests would be highly useful. The purpose of this study was to develop such a test using fractal analysis which is increasingly being applied in science, especially in the field of biomedicine. A total of 53 circumanal gland tumors were chosen from our department archives. After a precise histological classification according to the World Health Organization classification, the number of de novo classified samples was as follows: 15 adenomas, 11 epitheliomas, 21 well differentiated carcinomas, 6 poorly differentiated carcinomas. Ten samples of normal circumanal gland were also included as control. All samples were immunohistochemicaly stained with vimentin. All immunohistochemical reactions were photographed at two different magnifications -100X and 400X and converted to 1 bit in black and white (bitmap) images thus enhancing the positive vimentin reactions. These images were used for the assessment of fractal dimension applying the box counting method and computer software Fractalyse. To determine the significance of results, conventional statistics were performed using Statistica software. The overall vimentin stain score was significantly higher in epitheliomas and carcinomas than in normal circumanal glands (CG) or adenomas. Mean values of fractal dimension estimated at magnification 100X and 400X were as follows: normal CG 1.318 and 1.372, CG adenomas 1.384 and 1.408, CG epitheliomas 1.547 and 1.597, CG well differentiated carcinomas 1.569 and 1.607, CG poorly differentiated carcinomas 1.679 and 1.723. Significant differences (at level of 5%) of these values were observed between individual groups of CG adenomas or normal CG, and epitheliomas or carcinomas. The above results indicate vimentin immunohistochemistry staining and assessment of fractal dimension as an ancillary diagnostic method of choice when discerning between benign and malignant tumors of circumanal glands. Additional development of the method of fractal dimension assesment may yield a possibility for this tool to successfully discern between all of the types of CG tumors.

In September 2012, a 10-year-old, intact male, terrier mix breed dog was evaluated because of multiple, 0.5 to 1.2 cm in diameter, round, intradermal nodules around the anus. It had surgery to excise a firm, painful swelling in the left ventrolateral perianal region and the excision part was observed under light microscopy. The mass spreading in to sub acute was of left hind leg out from the ventro-lateral of anus, 1.2 cm×1 cm/ 0 cm×0.5 cm in size and 125 g in weight. A complete blood cell count, serum biochemistry panel, and urinalysis (cystocentesis sample) were evaluated. Significant laboratory data demonstrated microcytic anemia (hemoglobin of 6.4 mg/dL) and normal coagulation times. No remarkable abnormalities were found in the complete blood count and an ionized calcium of 1.91 mmol/L (reference range, 1.1-1.3 mmol/L) was confirmed hypercalcemia. On cytologic and histopathologic examinations, evaluation of the aspirate revealed a prominent population of round-to-polygonal nucleated cells arranged as cohesive groups with isolated individual cells. A mild degree of anisocytosis and anisokaryosis was observed. In addition, smaller reserve type cells, with darker cytoplasm and a higher nucleocytoplasmic ratio. The adenomas generally retain the lobular architecture, but some may contain focal areas of cellular pleomorphism. These changes may suggest malignant transformation and have led to discordant interpretations, the well-developed stroma surrounding the lobules and hepatoid cells was noted. Ulceration, hemorrhage, necrosis and secondary infection with inflammatory cell infiltrates are common. These cytology and histopathology features are consistent with hepatoid gland adenoma.

The aim of this study was to determine serum magnesium concentrations in dogs with benign and malignant tumors of the perianal glands. The magnesium concentration was determined in samples taken from 45 tumor-affected and 17 healthy males. Twenty one dogs suffered from malignant tumors (Malignant group), while benign changes were diagnosed in 24 cases (Non-malignant group). All dogs with neoplastic disease were treated with antiandrogens and antiestrogens. Determination of magnesium concentrations in serum obtained from dogs before the start of treatment (baseline), and one and six months later was performed using atomic absorption spectrophotometry. One-way ANOVA and the post-hoc Tukey's HSD test were used to compare differences between the groups investigated and time-related changes. Significantly higher serum magnesium concentrations were found in the group with malignant tumors when compared to the control and non-malignant groups (P<0.001). Serum magnesium concentrations in dogs with non-malignant neoplastic changes had increased gradually by 17% and 41% at one and six months when compared to the baseline values (P<0.05). In conclusion, the malignant neoplastic process in dogs was associated with a higher baseline serum magnesium concentration. Thus, determination of the serum magnesium concentration might be helpful for diagnostic differentiation between malignant and benign perianal tumors in dogs.

This case report describes a 7-year-old male cocker spaniel dog with multiple perianal infundibular follicular cysts. Clinically the dog had moderate anal sacculitis, peri-anal pruritus causing it to 'scoot' and lick the area. On examination of the perianal area, there were over 100 firm, well circumscribed papules, ranged from 0.2 to 0.5 cm in diameter with a central pore, and were found in the perianal region. Alopecia was present in the perianal region. The skin tissue in the perianal region resected surgically was submitted for histological examination. Microscopically, the tissue revealed multiple dilated cysts filled with keratins and the papules corresponded to infundibular follicular cysts. The affected dog showed moderate anal sacculitis. Anal sacculitis commonly causes repeated scooting or licking the area around the anus. Therefore, the multiple follicular cysts in the present case appear to be primarily a sequela to chronic external trauma to the perianal area, probably in response to anal sacculitis. To the best of the authors' knowledge, the present report is the first documented case of multiple perianal infundibular follicular cysts in a dog.

The records of 33 dogs that had perianal fistula disease treated with en bloc surgical excision and bilateral anal saculectomy, and that were perioperatively administered an exclusive white fish and potato diet, were reviewed to determine outcome. By 1 year after surgery, 87.9% of the dogs had complete or near-complete resolution of visible fistula disease, while only 20.7% continued to have mild intermittent clinical signs. Fecal incontinence was not reported in any dog. Overall, complications were considerably less in both severity and frequency when compared with previous reports.

A four-year-old, entire male domestic cat was referred for assessment of a large abdominal mass of three-weeks duration. Diagnostic imaging suggested the presence of either splenic neoplasia, an abdominal abscess or haematoma. A coeliotomy was performed and an enlarged, irregular mass, including the left kidney and adrenal gland, was identified. The mass was removed, requiring a left adrenalo-uretero-nephrectomy. The aorta was accidentally punctured during the procedure, resulting in paraplegia. Given a poor prognosis, the owners decided to have the cat euthanased. Histological examination of the mass was characteristic of a chronic expanding haematoma.

OBJECTIVE: To investigate the effect of cyclosporine (2 or 5 mg/kg every 24 hours) on perianal fistulae (PAF) lesions. STUDY DESIGN: Blinded randomized, prospective trial. ANIMALS: Dogs (n = 20) with perianal fistulae. METHODS: Dogs were randomly assigned to administration of either 2 mg/kg (n = 10) or 5 mg/kg (n=10) of cyclosporine orally every 24 hours for 8 weeks. Lesion surface area was measured, lesion severity was graded using a visual analog scale, and the presence and severity of clinical signs recorded every 2 weeks. RESULTS: Lesion variables were significantly reduced in both groups after 8 weeks and owners also reported a reduction in clinical sign severity. The 5 mg/kg dose rate significantly accelerated lesion resolution compared with 2 mg/kg. In the 2 mg/kg group, 20% of dogs had complete resolution of clinical signs and 10% had resolution of lesions. In the 5 mg/kg group, 40% of dogs had complete resolution of clinical signs and 60% had resolution of lesions. CONCLUSIONS: A dose rate of 5 mg/kg every 24 hours was more effective at reducing the surface area and severity of PAF lesions than 2 mg/kg every 24 hours but less effective at resolving PAF lesions than previous studies using dose rates > or =5 mg/kg every 12 hours. CLINICAL RELEVANCE: Cyclosporine at 5 mg/kg every 24 hours may be useful for the palliation of PAF lesions.

A 66-year-old Dutchman, living in Mali, presented with an extensive progressive perianal ulcer despite local and antibiotic treatment. Microscopic examination of the stool revealed Entamoeba histolytica/dispar cysts and phagocytosing trophozoites were seen in fresh scrapings of the ulcer, a diagnostic feature of infection with E. histolytica. The diagnosis was cutaneous amoebiasis and the patient was effectively treated with metronidazole and local debridements. Primary cutaneous amoebiasis is a rare disease. Diagnosis and treatment are relatively simple but lack of familiarity with the disease may lead to misdiagnosis or diagnosis at a late stage ofthe infection.
