Factors associated with cellulitis in lymphoedema of the arm - an international cross-sectional study (LIMPRINT).

BACKGROUND: Lymphoedema is a globally neglected health care problem and a common complication following breast cancer treatment. Lymphoedema is a well-known predisposing factor for cellulitis, but few have investigated the risk factors for cellulitis in this patient cohort on an international level. The aim of this study was to identify the frequency of cellulitis in patients with lymphoedema of the arm, including potential risk factors for cellulitis. METHODS: An international, multi-centre, cross-sectional study including patients with clinically assessed arm lymphoedema. The primary outcome was the incidence of cellulitis located to the arm with lymphoedema within the last 12 months, and its potential associated risk factors. The secondary outcome was life-time prevalence of cellulitis. Adults with clinically-assessed arm lymphoedema/chronic oedema (all causes) and able to give informed consent were included. End-of-life-patients or those judged as not in the patient's best interest were excluded. Both univariable and multivariable analysis were performed. RESULTS: A total of 2160 patients were included from Australia, Denmark, France, Ireland, Italy, Japan, Turkey and United Kingdom. Secondary lymphoedema was present in 98% of the patients; 95% of these were judged as related to cancer or its treatment. The lifetime prevalence of cellulitis was 22% and 1-year incidence 11%. Following multivariable analysis, factors associated with recent cellulitis were longer swelling duration and having poorly controlled lymphoedema. Compared to having lymphoedema less than 1 year, the risk increased with duration: 1-2 years (OR 2.15), 2-5 years (OR 2.86), 5-10 years (OR 3.15). Patients with well-controlled lymphoedema had a 46% lower risk of cellulitis (OR 0.54, 95% CI 0.39-0.73, p < 0.001). More advanced stages of lymphoedema were associated with cellulitis even after adjustment for swelling duration and control of swelling by logistic regression (stage II OR 5.44, stage III OR 9.13, p = 0.002), demonstrated in a subgroup analysis. CONCLUSION: Patients with advanced arm lymphoedema are at particular risk of developing cellulitis. Prevention of lymphoedema progression is crucial. The results lend towards a positive effect of having well-treated lymphoedema on the frequency of cellulitis.

Erysipelas with preferential brain and skin involvement in a Mediterranean bottlenose dolphin Tursiops truncatus.

Infections by Erysipelothrix rhusiopathiae occur in domestic animals and cause the disease known as 'erysipelas'. The ubiquity of Erysipelothrix spp. makes infection possible in a wide range of vertebrates and invertebrates. Cetaceans are highly susceptible to erysipelas, especially those under human care. The number of cases documented in wild cetaceans is low, the pathogenesis is incompletely understood, and the full spectrum of lesions is not well defined. The possible serotypes and species of the genus that can cause disease are unknown. In October 2022, a common bottlenose dolphin Tursiops truncatus stranded in Vilassar de Mar (Catalonia) showing skin lesions consistent with 'diamond skin disease', a characteristic lesion of erysipelas shared by swine and cetaceans. Necropsy was performed following standardized procedures, and multiple samples were taken for histopathology and bacteriology. Erysipelothrix sp. grew in pure culture in many tissue samples. Genetic characterization by multi-locus sequence analysis identified the species as E. rhusiopathiae. Histologically, the main lesions were an intense suppurative vasculitis of leptomeningeal arteries and veins with abundant intramural Gram-positive bacilli and meningeal hemorrhages. Meningeal lesions were considered the cause of death. The affected skin showed moderate suppurative dermatitis. Herein we document a case of erysipelas in a Mediterranean common bottlenose dolphin with unusual lesions in the leptomeningeal vessels and marked skin tropism. To our knowledge, this is the first case of severe brain involvement in erysipelas in a cetacean. We also provide a review of available cases in wild cetaceans, to highlight the characteristics of the disease and improve future diagnosis.

Current challenges in diagnosing and treating infectious skin diseases - a case series. / Choroby zakazne skóry jako wciaz aktualny problem diagnostyczny i terapeutyczny ­ przeglad nietypowych przypadków klinicznych.

Infectious skin diseases constitute a significant public health problem. Despite the systematic development of many modern diagnostic and therapeutic tools, they still pose a serious challenge for clinicians. Due to their prevalence and mild course in most cases, they are often marginalized, which can delay their diagnosis and treatment initiation. Such an approach in more clinically advanced cases can have serious consequences, sometimes leading to tragic outcomes. This work presents a series of four cases of common infectious skin diseases with an unusually atypical clinical picture: the history of a 49-year-old female patient with recurrent erysipelas of the right lower leg co-occurring with a SARS-CoV-2 infection, a 75-year-old male patient with a generalized form of herpes zoster, a 38-year-old female patient with a complicated severe course of head lice, and a 34-year-old male patient with a severe form of post-steroid mycosis. In each of these cases, difficulties in making the correct diagnosis were highlighted, even though they represent some of the most common bacterial, viral, parasitic, and fungal dermatoses. The paper discusses the risk factors for these diseases, the pathophysiology of their atypical course, the effects and challenges in the therapeutic approach conducted. Infectious skin dermatoses require aggressive treatment and should never be underestimated.

Compression Therapy in Dermatology. / Terapia compresiva en Dermatología.

The benefit of lower limb compression therapy is not limited to chronic venous insufficiency or/and lymphoedema. Thanks to its anti-edema and anti-inflammatory effects, compression therapy is considered a beneficial adjuvant therapy to treat atypical wounds, inflammatory dermatoses, cellulitis, and traumatic wounds in the absence of contraindications. Strict contraindications are limited to severe peripheral arterial disease and decompensated heart failure. The variability of commercially available compression materials and systems, such as short-stretch bandages, multi-component systems, zinc oxide bandages, medical adaptive compression systems, ulcer compression stockings or medical compression stockings, facilitates the adaptation of compression therapy to the individual needs of each patient. Compared to venous leg ulcers, low pressures of 20mmHg are often sufficient to treat dermatological disorders, with higher patient tolerance and compliance.

Systemic Erysipelas Outbreak among Free-Ranging Bottlenose Dolphins, San Diego, California, USA, 2022.

We diagnosed fatal Erysipelothrix rhusiopathiae sepsis in 3 stranded bottlenose dolphins (Tursiops truncatus) during summer 2022, in San Diego, California, USA. The previously undetected disease in this relatively small, regional population of dolphins most likely indicates an environmental or biological change in the coastal ocean or organisms.

Immunogenicity and Protection by DnaK and SpaA Recombinant Proteins Against Erysipelothrix Rhusiopathiae in a Murine Model.

BACKGROUND/AIMS: Swine erysipelas is a disease caused by Erysipelothrix rhusiopathiae, a Gram-positive bacillus, which has great economic importance because it leads to the loss of the swine herd. To control this disease, animals are immunized with a cellular vaccine of killed or attenuated E. rhusiopathiae, but even with herd vaccination, cases of swine erysipelas outbreaks have been reported in the United States, China and Japan, leading to the search for other antigenic components of the bacteria that may promote greater protection against E. rhusiopathiae. The surface protein SpaA from E. rhusiopathiae has been shown to be a candidate to constitute a subunit vaccine, since it has already been reported to induce a host immune response against the bacterium. DnaK, a hsp70 molecular chaperone, also seems to be a good candidate in the composition of a vaccine, as it has been demonstrated to be an antigenic protein of the bacteria. METHODS: This work evaluated the immunogenicity and protection induced by the E. rhusiopathiaee SpaA and DnaK recombinant proteins in a murine model, by intramuscular administration to mice with two doses of 100 µg at 21-day interval between them. The candidate proteins were tested either separately and together, compared with the commercial vaccine and the non-vaccination condition, and mice were challenged with a virulent strain of E. rhusiopathiae. Serum was collected to assess the produced antibodies and peripheral blood cells, whereas spleen and kidney tissues were assayed for E. rhusiopathiae presence by colony counting. RESULTS: A survival curve of the animals was performed, which confirmed the protection induced by the proteins. IgG antibodies increased in the animal serum inoculated with the proteins when compared to the control, and a significant delay in disease symptoms was observed. CONCLUSION: These results suggest that E. rhusiopathiae DnaK and SpaA are immunogenic in mice and interfere with the disease development.

Misdiagnosis of Uncomplicated Cellulitis: a Systematic Review and Meta-analysis.

BACKGROUND: Cellulitis is a clinical diagnosis with several mimics and no gold standard diagnostic criteria. Misdiagnosis is common. This review aims to quantify the proportion of cellulitis misdiagnosis in primary or unscheduled care settings based on a second clinical assessment and describe the proportion and types of alternative diagnoses. METHODS: Electronic searches of Medline, Embase and Cochrane library (including CENTRAL) using MeSH and other subject terms identified 887 randomised and non-randomised clinical trials, and cohort studies. Included articles assessed the proportion of cellulitis misdiagnosis in primary or unscheduled care settings through a second clinical assessment up to 14 days post initial diagnosis of uncomplicated cellulitis. Studies on infants and patients with (peri-)orbital, purulent and severe or complex cellulitis were excluded. Screening and data extraction was conducted independently in pairs. Risk of bias was assessed using a modified risk of bias tool from Hoy et al. Meta-analyses were undertaken where ≥ 3 studies reported the same outcome. RESULTS: Nine studies conducted in the USA, UK and Canada, including a total of 1600 participants, were eligible for inclusion. Six studies were conducted in the inpatient setting; three were in outpatient clinics. All nine included studies provided estimates of the proportion cellulitis misdiagnosis, with a range from 19 to 83%. The mean proportion misdiagnosed was 41% (95% CI 28 to 56% for random effects model). Heterogeneity between studies was very high both statistically (I2 96%, p-value for heterogeneity < 0.001) and clinically. Of the misdiagnoses, 54% were attributed to three conditions (stasis dermatitis, eczematous dermatitis and edema/lymphedema). DISCUSSION: The proportion of cellulitis misdiagnosis when reviewed within 14 days was substantial though highly variable, with the majority attributable to three diagnoses. This highlights the need for timely clinical reassessment and system initiatives to improve diagnostic accuracy of cellulitis and its most common mimics.

PREDICT-crFMF score: A novel model for predicting colchicine resistance in children with familial Mediterranean fever.

OBJECTIVES: To develop a novel scoring system to predict colchicine resistance in Familial Mediterranean fever (FMF) based on the initial features of the patients. METHODS: The medical records of patients were analyzed prior to the initiation of colchicine. After generating a predictive score in the initial cohort, it was applied to an independent cohort for external validation of effectiveness and reliability. RESULTS: Among 1418 patients with FMF, 56 (3.9%) were colchicine resistant (cr) and 1312 (96.1%) were colchicine responsive. Recurrent arthritis (4 points), protracted febrile myalgia (8 points), erysipelas-like erythema (2 points), exertional leg pain (2 points), and carrying M694V homozygous mutation (4 points) were determined as the parameters for predicting cr-FMF in the logistic regression model. The cut-off value of 9 was 87% sensitive and 82% specific to foresee the risk of cr-FMF in the receiver operating characteristic. Validation of the scoring system with an independent group (cr-FMF = 107, colchicine responsive = 1935) revealed that the cut-off value was 82% sensitive and 79% specific to identify the risk of cr-FMF. CONCLUSIONS: By constructing this reliable and predictor tool, we enunciate that predicting cr-FMF at the initiation of the disease and interfering timely before the emergence of complications will be possible.

Erysipelothrix rhusiopathiae-specific T-cell responses after experimental infection of chickens selectively bred for high and low serum levels of mannose-binding lectin.

Erysipelas, caused by infection with Erysipelothrix rhusiopathiae (ER) is an important emerging disease in laying hens. We have earlier observed prominent mannose-binding lectin (MBL) acute phase responses in experimentally ER infected chickens. The present study aimed to further examine immune responses to ER by using chickens selectively bred for high (L10H) and low (L10L) serum MBL levels. Chickens were infected with ER at 3 weeks of age and immune parameters and bacterial load were monitored in blood until day 18 after infection. Blood and spleen leukocytes collected on day 18 were stimulated in vitro with ER antigens and blast transformation of different T-cell populations was assessed. The ER infection gave a very varied outcome and no clear differences were observed between L10H and L10L chickens with respect to leukocyte counts, bacterial load or clinical outcome. Nonetheless, rapid innate responses, e.g., heterophilia and increased serum MBL levels were noted in bacteraemic chickens. All ER infected chickens also showed transient increased expression of mannose receptor MRC1L-B and decreased expression of major histocompatibility complex II on monocytes day 1 after infection indicating monocyte activation or relocation. In vitro ER stimulation showed antigen specific blast transformation of CD4+, TCRγ/δ-CD8αß+ and TCRγ/δ+CD8αß+ spleen cells from all infected chickens. For CD4+ and TCRγ/δ-CD8αß+ cells the proportions of blast transformed cells were significantly higher for samples from L10L chickens than those for samples from L10H chickens. This is the first observation of ER-specific T-cells in chickens and interestingly a Th1-type response comprising cytotoxic T-cells was indicated.

[Soft tissue infections]. / Weichgewebeinfektionen.

Acute skin and soft tissue infections are among the most frequent infections in medicine. There is a broad spectrum including simple local infections as well as severe and life-threatening diseases. Along with Staphylococcus aureus, group A Streptococci are mainly responsible for these illnesses. The therapeutic approach ranges from antiseptic local treatments to administering systemic antibiotics or emergency surgery. Treating physicians often face challenges when presented with soft tissue infections due to a great discrepancy between the first impression of the disease compared to a possibly quick progression as well as the wide range of sometimes confusing historic terms and definitions being used in the English and German language, for instance pyoderma, erysipelas or phlegmon. A recently more popular collective term emphasized by clinical trials is "acute bacterial skin and skin structure infections" (ABSSSI).

Erysipelas of the leg: A cross-sectional study of risk factors for recurrence.

BACKGROUND: Erysipelas is a common infection of the superficial layer of skin. The main causative agent is group A ß-hemolytic streptococci. One of the most challenging aspects of this disease is its high rate of recurrence. OBJECTIVES: To identify risk factors for recurrence of erysipelas of the leg. PATIENTS AND METHODS: We included in a cross-sectional study all patients hospitalized for erysipelas of the leg seen at the dermatology department of the Ibn Rochd University Hospital in Casablanca, Morocco, from January 2015 to April 2020. Patients were divided into two groups: those with a single episode (SE) and those with recurrent erysipelas (RE). These two groups were compared for clinical and laboratory characteristics, with particular focus on systemic and local risk factors. RESULTS: The study included 270 patients, of whom 132 had SE and 138 had RE. Age, gender, hospital stay as well as laboratory findings did not differ significantly between the two groups. In multivariable analysis, cutaneous disruption [adjusted odds ratio (aOR)=1.9; 95% confidence interval (95% CI): 1.0-3.71], lymphedema [aOR=19.6; 95% CI: 8.0-57.2], and obesity [aOR=2.3; 95% CI: 1.1-5.2] were significantly associated with RE. Venous insufficiency and diabetes were not found to be associated with risk of recurrence. CONCLUSION: Our results suggest that erysipelas is a potentially chronic disease and patients with identified local risk factors or obesity should be considered as exposed to recurrence and considered as targets for antibiotic prophylaxis and other preventive methods.

Fungal infections of the feet in patients with erysipelas of the lower limb: is it a significant clinical problem?

BACKGROUND: Erysipelas is a bacterial infection of the superficial layers of the skin usually caused by Group A Streptococci, often seen in clinical practice. Fungal infections of the feet and elderly age are some of the most significant risk factors for the infection. The aim of the study was to evaluate the frequency of fungal infections from different regions of the feet in patients with erysipelas. METHODS: 56 patients with clinically diagnosed erysipelas and 56 healthy individuals were clinically examined and tested for fungal infection in three locations: toenails, interdigital space, and soles. The collected samples were evaluated under a microscope and then mycological cultures on Sabouraud's medium were prepared. After 4 weeks of incubation, the cultures were analysed with the identification of particular pathogens. RESULTS: 42.9% (24/56) of the patients with erysipelas had positive mycological cultures. Toenails and interdigital spaces (both 62.5%) were the most frequently affected areas, followed by soles (37.5%). The most common pathogen was T. rubrum (43.18%), followed by Candida spp. (27.27%), and T. mentagrophytes var.interdigitale (13.63%). Only 14.3% (8/56) of the samples taken from the control group were positive and T.rubrum was the only type of fungus cultured. CONCLUSIONS: Fungal infections of the feet are important risk factors for the first episode as well as recurrent erysipelas. Prevention and early treatment of fungal infections, especially in elderly people, can significantly reduce the incidence of erysipelas.

Risk factors of recurrent erysipelas in adult Chinese patients: a prospective cohort study.

BACKGROUND: Erysipelas is a common skin infection that is prone to recur. Recurrent erysipelas has a severe effect on the quality of life of patients. The present study aimed to investigate the risk factors of recurrent erysipelas in adult Chinese patients. METHODS: A total of 428 Chinese patients with erysipelas who met the inclusion criteria were studied. The patients were divided into the nonrecurrent erysipelas group and the recurrent erysipelas group. Clinical data were collected on the first episode and relapse of erysipelas. The patients were followed up every 3 months. Statistical analysis was performed to analyze and determine the risk factors of erysipelas relapse. RESULTS: Univariate analysis was performed to analyze the data, including surgery, types of antibiotics administered in the first episode, obesity, diabetes mellitus, venous insufficiency, lymphedema, and malignancy. The differences between the groups were statistically significant (p < 0.05). The Cox proportional hazards regression model analysis showed that the final risk factors included surgery, obesity, diabetes mellitus, venous insufficiency, and lymphedema. CONCLUSIONS: Surgery, obesity, diabetes mellitus, venous insufficiency, and lymphedema are considered as risk factors for recurrent erysipelas.

Quantification of IgY to Erysipelothrix rhusiopathiae in serum from Swedish laying hens.

BACKGROUND: Erysipelas, caused by Erysipelothrix rhusiopathiae (ER), is an important emerging disease in free-range and organic egg-production. The aim of the present study was to assess if quantification of ER specific IgY titers may aid the understanding of erysipelas in commercial laying hens. The methodology was validated with sequentially collected sera from experimentally ER infected SPF-chickens and subsequently applied on sera from Swedish commercial laying hens collected during and after outbreaks of erysipelas or collected at slaughter from healthy hens housed in furnished cages, barn production or in organic production (with outdoor access). RESULTS: In experimentally infected SPF-chickens, titers to ER were significantly increased approximately one week after infection while IgY to ER in uninfected age-matched controls remained low. Also chickens infected with low doses of ER, not displaying clinical signs of disease and with low recovery of ER in blood samples showed high titers of IgY to ER. For laying hens during and after erysipelas outbreaks the majority of samples were considered positive for antibodies to ER with a large variation in levels of IgY titers to ER between individuals. For healthy laying hens at slaughter all samples were deemed positive for antibodies to ER. An influence of flock on levels of IgY titers to ER was observed for both healthy hens and hens during erysipelas outbreaks. For healthy laying hens at slaughter no influence of the housing systems included in the study, history of erysipelas outbreaks at the farm or vaccination on levels of IgY titers to ER was noticed. CONCLUSIONS: Taken together, these results show that high numbers of commercial laying hens showed high IgY titers to ER, comparable to those elicited by experimental ER infection, indicating that ER or bacteria that raises antibodies that cross-react with ER are common in this environment.

Is coverage of S. aureus necessary in cellulitis/erysipelas? A literature review.

BACKGROUND: Empirical treatment of patients with cellulitis/erysipelas usually targets both streptococci and methicillin-sensitive S. aureus (MSSA). However, the recommendation to empirically cover MSSA is weak and based on low-quality evidence. METHODS AND OBJECTIVE: A systematic review was conducted in PubMed and clinical trial registries to assess the role of S. aureus in cellulitis/erysipelas and the need for empirical MSSA coverage. RESULTS: Combined microbiological and serological data, and response to penicillin monotherapy suggest that streptococci are responsible for the vast majority of cases of cellulitis/erysipelas. However, most cases are non-culturable and the specificity of microbiological and serological studies is questionable based on recent studies using molecular techniques. According to epidemiological data and three randomized controlled trials, empirical coverage of methicillin-resistant S. aureus (MRSA) is not recommended for most patients, despite the high prevalence of MRSA in many areas. If MRSA is indeed not an important cause of uncomplicated cellulitis/erysipelas, then the same may apply to MSSA. Based on indirect comparison of data from clinical studies, cure rates with penicillin monotherapy (to which most MSSA are resistant) are comparable to the cure rates reported in many studies using wider-spectrum antibiotics. CONCLUSION: Considering the limitations of microbiological studies in identifying the pathogens responsible for cellulitis/erysipelas, treatment needs to be guided by clinical trials. Trials comparing penicillin or amoxicillin monotherapy to MSSA-covering regimens are needed to definitively answer whether empirical coverage of MSSA is needed and to identify the subset of patients that can be safely treated with penicillin or amoxicillin monotherapy.

Diagnostic Value of Laboratory Parameters for Distinguishing Between Herpes Zoster and Bacterial Superficial Skin and Soft Tissue Infections.

Clinical differentiation between herpes zoster and bacterial superficial skin and soft tissue infections of the face can be difficult. In addition, diagnosis can be complicated by bacterial superinfection of lesional herpes zoster. The aim of this study was to determine whether inflammatory parameters, such as C-reactive protein (CRP) and blood counts, might be reliable biomarkers to distinguish between skin and soft tissue infections and herpes zoster when the face is infected. The study data (multivariate analysis and area under the curve) identified CRP (0.880) and leukocytes (0.730) together as the parameters that best discriminate between skin and soft tissue infections and herpes zoster. A CRP threshold ≥ 2.05 mg/dl indicated a diagnosis of skin and soft tissue infection with a sensitivity of 80% and specificity of 83.8%. For leukocytes ≥ 7.3×109/l, diagnosis of skin and soft tissue infection had a sensitivity of 75% and specificity of 67.6%. Thus, when differential diagnosis is difficult, CRP and leukocytes should be determined, while parameters such as neutrophils or immature granulocytes do not add diagnostic value.

Haemophilus parainfluenzae-related cellulitis of the penis following tearing of a short frenulum.

INTRODUCTION: Infectious cellulitis is a common disease, mostly affecting the lower extremities and the face but only rarely the genitalia. OBSERVATION: A 24-year-old male patient presented with acute erythematous edema of the penile shaft and foreskin present for 48hours. Gentle retraction of the foreskin revealed a short frenulum with a small area (2-3mm) of erosion. He had had unprotected genital and orogenital sex three days before with his usual female partner and reported tearing of the frenulum during intercourse. Ampicillin-sensitive Haemophilus parainfluenzae was isolated from the swab taken from the erosion of the frenulum. Clinical remission was obtained following oral administration of amoxicillin and clavulanic acid. DISCUSSION: We describe not only the first case of Haemophilus parainfluenzae-associated cellulitis of the penis but also the first report of penile cellulitis following erosion of a short frenulum during sexual intercourse.

Erysipelas Complicated with Acute Exudative Pericarditis.

Erysipelas is a common skin infection of the upper dermis. Its most common complications are local; these include abscess formation, skin necrosis, etc. In the present article, we introduce a case of a 75-year-old patient with erysipelas of the face complicated with acute exudative pericarditis. The patient came to Kaunas Clinical Hospital complaining of extreme fatigue and fever, oedema of the left side of the face, and erythema typical for erysipelas. The patient also felt sternum and epigastric pain, especially during breathing, and dyspnoea. Heart work was rhythmic 100 bpm; blood pressure was 142/70 mmHg. Pericardial friction rub was heard over the left sternal border. There were no alterations in other systems. In the electrocardiogram, concave ST segment elevation in leads II, III, and aVF was identified. In addition, during hospitalisation, the patient experienced atrial fibrillation paroxysm, which was treated with amiodarone intravenously. The blood test showed C-reactive protein: 286 mg/L; white blood cells: 20 × 109/L; troponin I was within the normal range. During echocardiography, pericardial fluid in pericardial cavity was identified. As no changes in troponin I were observed, according to the ST segment elevation, the woman was diagnosed with erysipelas of the left side of the face complicated with acute exudative pericarditis. Antibacterial treatment of cephalosporins was administered. After the treatment, C-reactive protein decreased to 27.8 mg/L; whereas, in the electrocardiogram, the return of the ST segment to the isoline was observed, and pericardial fluid resorbed from the pericardial cavity. To the best of the authors' knowledge, this case is a rare combination of erysipelas complicated with acute exudative pericarditis.

Cutaneous manifestations of Campylobacter jejuni infection: A case report and review of the literature.

A 51 year old man with active follicular lymphoma presented with several days of erythematous skin nodules on all extremities two weeks after a self-limited diarrheal illness. All serum immunoglobulin levels were found to be low. Blood cultures grew Campylobacter jejuni. The patient was given one week of azithromycin with complete resolution of his skin nodules. The literature of skin manifestations seen in active Campylobacter jejuni infection are reviewed. The majority of cases occur in immunocompromised hosts, many with low or no serum immunoglobulin levels. Postulated mechanisms include a lack of secretory IgA in intestinal mucosa predisposing susceptible patients to translocated enteric pathogens however the precise pathogenesis underlying cutaneous manifestations are unknown.

Rare coexistence of unilateral erythema nodosum with erysipelas in the area of previous adder bite.

INTRODUCTION: Erysipelas is an acute inflammation of skin and subcutaneous tissue. Erythema nodosum is the most frequent form of panniculitis considered as a reaction to different factors, most commonly infections, especially streptococcal. CASE PRESENTATION: A 74-year-old male presented to hospital due to skin lesions involving the same area he was bitten by an adder six months earlier. On the admission well-demarcated erythema and oedema on the right shin with accompanying fever were noted. Erysipelas was diagnosed and intravenous ceftriaxone was administered. Two days later a few tender nodules within that unilateral location appeared. Based on the clinical and histopathological picture diagnosis of Bävferstedt subtype (erythema nodusum migrans, ENM) was made. The treatment was continued, further followed by doxycycline orally resulting in clinical improvement. CONCLUSIONS: This case presents an unusual coexistence of erysipelas and erythema nodosum migrans, the more it was observed on the primary adder bite area and occurred in a man. Most probably, adder's venom could lead to disturbed blood and lymph flow what predisposed to erysipelas, which, as streptococcal infection, could trigger ENM.
