Use of bosentan for digital ulcers related to systemic sclerosis: a real-life retrospective French study of 89 patients treated since specific approval.

OBJECTIVES: Ischaemic digital ulcers (DUs) are a common complication of systemic sclerosis (SSc). This study aimed to characterize patients with SSc and ongoing DUs treated with the endothelin receptor antagonist bosentan in clinical practice in France. METHOD: An observational, retrospective, longitudinal study was conducted in 10 French expert centres. Medical records from randomly selected adult SSc patients who received treatment with bosentan for DU prevention from March 2007 to December 2010 were analysed. The primary objective was to determine the profile of patients at treatment initiation. Secondary objectives were to monitor bosentan dosing, treatment schedule, and reasons for treatment termination. RESULTS: The study included 89 patients (mean age 52 years, 69% female, 44% diffuse cutaneous SSc). At bosentan treatment initiation, the mean duration of Raynaud's phenomenon was 15 ± 12 years, and the mean time since first episode with DU was 6.5 ± 7 years. Most patients had a history of at least two episodes with DUs, separated by < 12 months (61%), and had received intravenous iloprost (63%). Previous DU complications included auto-amputation (8%), surgical amputation (6%), osteitis (6%), and gangrene (4.5%). Active smokers (25%) had a history of significantly more surgical amputation (p = 0.004) and osteitis (p = 0.004) than non-smokers. At least one active DU at bosentan initiation was detected in 82% of patients. Bosentan was used according to prescription guidelines and was well tolerated; six patients (7%) withdrew from treatment because of raised liver enzymes. CONCLUSIONS: Patients treated with bosentan for DU prevention in France have severe, refractory, ongoing ulcerative disease. Active smoking was correlated to a history of DU complications. Tolerance of bosentan was comparable to previous studies.

[Assessment of tele-expertise among elderly subjects in retirement homes]. / Une expérience de télé-expertise en établissement d'hébergement de personnes âgées dépendantes (EHPAD).

BACKGROUND: Chronic wounds (leg ulcers, pressure ulcers, diabetic foot ulcers, etc.) constitute a real public health problem and engender high economic and human costs. Due to the declining physical and mental conditions of our elderly subjects and their rural environment, we created a computer program to assist with chronic wound management in elderly subjects living in retirement homes and to reduce the amount of ambulance transportation. MATERIALS AND METHODS: Each participating establishment was provided with a digital camera and its own secure e-mail address in order to allow photographs to be sent anonymously. Patients with chronic wounds entailing treatment difficulties were included. Details were recorded of the number of tele-expertise consultations given, the chronic wound type, the number of hospitalizations or medical consultations, and the number of ambulance trips avoided. The project was evaluated at 1 year. RESULTS: Of the 40 establishments invited to take part, 22 agreed to do so but only the first 10 respondents were accepted for participation in the pilot feasibility study. Funding ("Health and social prize" provided by the Haute-Vienne region Social Security Office - CPAM) was used to purchase the cameras. Beginning on 15 April 2010, 10 establishments for the elderly sent photographs of 34 patients presenting 26 chronic wounds and tele-expertise was provided for 10 pressure ulcers, two diabetic feet and 14 leg ulcers. CONCLUSION: Over a two-year period, this program helped avoid 20 trips for patients and enabled rapid hospitalization of nine patients by the university hospital by optimizing chronic wound management for patients residing in establishments for the elderly.

Imatinib mesylate in scleroderma-associated diffuse skin fibrosis: a phase II multicentre randomized double-blinded controlled trial.

BACKGROUND: Imatinib mesylate is a potent inhibitor of platelet-derived growth factor and transforming growth factor-ß signalling pathways which may play a role in systemic sclerosis (SSc)-associated skin changes. OBJECTIVES: We aimed primarily at assessing the efficacy of imatinib mesylate in scleroderma skin fibrosis. METHODS: We performed a phase II double-blinded trial on patients with scleroderma with either morphoea involving > 20% of body surface area or SSc with extensive skin involvement: modified Rodnan Skin Score (mRSS) ≥ 20/51. Each patient was randomized to receive either imatinib mesylate 400 mg or placebo daily for a total of 6 months, and then was followed up 6 months after therapy discontinuation. Skin fibrosis was assessed by mRSS and measurement of the dermal thickness using skin biopsies performed at inclusion and at 6 months of treatment. In addition, quality of life (Dermatology Life Quality Index and modified Health Assessment Questionnaire for Scleroderma) was recorded at each visit, and pulmonary function before and after intervention. RESULTS: Twenty-eight patients were included in the study with a mean age of 48·9 years (range 30-71): 25 had a diagnosis of a SSc and three of diffuse cutaneous scleroderma. Demographic data, frequency of organ involvement of SSc and mRSS were comparable between groups. At 6 months, the proportion of variation of mRSS from inclusion was not statistically significantly different between the two groups (median +0·10 in imatinib group vs. -0·16 in placebo group, P = 0·098). Similarly, changes in dermal thickness, quality of life and diffusion capacity for carbon monoxide were not significantly different between groups. CONCLUSIONS: This study failed to demonstrate the efficacy of imatinib 400 mg daily to improve skin fibrosis of diffuse scleroderma after 6 months of treatment based on validated outcome measurements.

[Photodynamic therapy for the treatment of extramammary Paget's disease]. / Traitement de la maladie de Paget extramammaire par photothérapie dynamique topique.

BACKGROUND: The usual treatment for extramammary Paget's disease (EMPD) is surgery, but this approach may have grave functional and physical consequences, as well as high recurrence rates. Topical photodynamic therapy (PDT) offers an optional approach for EMPD; it has a high complete response rate and there is no dose restriction. The aim of this study was to evaluate the efficacy and safety of PDT in the treatment of EMPD. PATIENTS AND METHODS: This series of patients was seen at a single centre between 1 December 2005 and 31 December 2010. All patients with histologically confirmed EMPD were included. Patients received two courses of PDT 21 days apart: 3 hours after topical application of methyl aminolevulinic acid emulsion, they underwent illumination with red light (570-670 nm) at a dose of 37 J/cm(2) for 10 minutes. In the event of relapse, a further cycle was given at week 6. RESULTS: Eight patients (seven female, one male) of a mean age of 69 years were included. After two series of two illuminations, seven patients were in complete clinical remission at 3 months and one patient was in partial remission. Five patients were still in complete clinical remission at 6 months. All patients had relapsed after a mean 8.4 months (4-14 months). The limiting factor appears to be pain occurring during illumination. Patients reported satisfaction with the disappearance of symptoms and a notable improvement in quality of life. DISCUSSION: The complete clinical response rate to PDT at month 6, after two series of two illuminations, was equivalent to that for surgery. Although the recurrence rate was high, this treatment may be repeated without functional or physical consequences. PDT resulted in disappearance of pain and improved quality of life.

[Historic malignant tumour: 27 observations]. / Tumeur maligne historique: 27 cas.

BACKGROUND: When used in the French medical literature to describe a pathological state, the word "historic" normally refers to tumours of startling appearance because of their size. It is difficult to understand how a patient can allow such tumours to continue to grow. We attempt to define this concept. PATIENTS AND METHODS: Two dermatologists carried out a retrospective, independent and comparative selection of photographs taken between 1978 and 2008 of malignant cutaneous tumours of unusual size given the histological diagnosis. Socio-professional, demographic, clinical, histological psychological data, and details of treatment history and progress were collected. RESULTS: Twenty-seven patients (11 M, 16 F) of mean age 74 years (34-99 years) presented a "historic" tumour. Twelve patients lived in rural regions. Five patients were company executives. The average duration of development of the "historic" tumours was 4.5 years (6-420 months). The tumours were classed histologically as epidermoid carcinomas (nine) and melanomas (seven). The mean size was 13 cm (6-30 cm). Psychiatric problems, membership of sects or dementia were noted for 13 patients. Treatment consisted of chemotherapy, radiotherapy or, less frequently, surgery. Eighteen patients died on average 13 months after diagnosis. DISCUSSION: "Historic" malignant tumour (also described in the literature as "giant" tumour) is a real-life fact. No studies have been made of a series of such patients. Despite histological diagnosis, the size was associated with slow tumoral progress and/or late treatment, chiefly accounted for by psychiatric disorders. Socio-professional data indicate that "historic" tumours are equally common in urban and rural areas.

High prevalence and risk factors of thromboembolism in stage IV melanoma.

BACKGROUND: Patients with cancer are at a high risk of thromboembolism (TE), which contributes to morbidity and mortality. Several case reports of thromboembolic events have been reported in patients with melanoma in the literature. OBJECTIVE: The aim of this study was to evaluate the prevalence of venous thromboembolism (VTE) in stage IV melanoma and determine risk factors, outcomes associated with the development of VTE and the number of haemorrhagic complications in patients under anti-coagulant treatment. PATIENTS AND METHODS: In this retrospective study, we included all consecutive patients with stage IV melanoma among 290 patients followed-up in the department of Dermatology each year between January 2005 and 31 December 2007. The diagnosis of VTE was confirmed by venous ultrasound, pulmonary perfusion-ventilation technetium scan and angiography. The primary outcome was to evaluate the number of TE diagnosed in stage IV melanoma patients. The secondary outcomes were to study the influence of TE on survival, its prevalence according to metastatic sites and to evaluate the number of haemorrhagic complications. RESULTS: Twenty-four VTE events were found [25.2% (CI: 16.5-34)]. Eighteen VTE were deep venous thrombosis in lower limbs associated with pulmonary embolism (PE) in 50% of cases. Twenty-five percent were asymptomatic and were revealed in the pulmonary scan performed for follow-up. Eight percent of VTE events revealed stage IV melanoma. Seventeen patients developed thrombosis at home after stopping heparin prophylaxis. Seven thrombotic events occurred during oral anti-coagulant therapy. CONCLUSION: We found as high a prevalence of VTE in stage IV melanoma as in lung and gastrointestinal cancers. All patients suffered thrombotic events when they were treated with chemotherapy and at home when they stopped heparin prophylaxis. Therefore, heparin prophylaxis should be maintained at home.

Photosensitivity associated with selective serotonin reuptake inhibitors.

Selective serotonin reuptake inhibitors (SSRIs) are a widely prescribed group of antidepressants. We report three cases of photosensitivity induced by fluvoxamine and paroxetine. These photoallergic reactions suggest cross-reactivity between different molecules. Methylation metabolism could explain common photosensitization. Although these drugs are widely prescribed, such photosensitization is rare. Nevertheless, we consider that clinicians and patients should be aware of the risk of photosensitization and these drugs should be stopped before phototherapy or prolonged sun exposure.

[Calciphylaxis treated by cinacalcet: a medical alternative to parathyroidectomy]. / Le traitement de la calciphylaxie par cinacalcet: une alternative médicale à la parathyroïdectomie.

Calciphylaxis is a rare necrotizing calcifying arteriolopathy, with a poor prognosis, for which there is currently no effective treatment. One of the major challenges of the therapy is normalizing the calcium-phosphate balance. Therefore, cinacalcet, which inhibit the production of parathormone by negative feedback, was considered a treatment option to control the evolution of calciphylaxis in a dialysed patient suffering from cholangiocarcinoma.

[One year follow-up of patients with bullous pemphigoid]. / Profil évolutif des patients atteints de pemphigoïde bulleuse au cours de la première année de traitement.

BACKGROUND: Since high doses of superpotent topical corticosteroids (CS) have been shown to improve the survival of bullous pemphigoid (BP) patients and to be more effective than oral CS, few studies have described the long-term course of the disease of these patients. We report the course of BP in the Limoges region of France based on patients diagnosed successively between 2002 and 2004. PATIENTS AND METHODS: This was a retrospective, single-centre study of 54 BP patients diagnosed with BP, conducted by the Department of Dermatology of the Limoges University Hospital over a 3-year period. We investigated epidemiological data, initial symptoms, type of treatment received and outcome at six and 12 months. The two primary end-points were disease control at month 12 and the combined outcome of deaths and relapse over the one-year follow-up period. We calculated the number of deaths, patients lost to follow-up, relapses, and remission at months 6 and 12. RESULTS: Between January 2002 and December 2004, 54 new BP patients were diagnosed in the Limoges Department of Dermatology: 18 male and 36 female, median age 84 years. Forty patients were treated with superpotent topical CS, 14 required adjuvant immunosuppressant treatment (oral CS, methotrexate, dapsone, mycophenolate mofetil, leflunomide). Over the first 6 months, 28 patients could not be further investigated due to death (n = 20) or loss to follow-up (n = 8). In the 26 patients evaluable for treatment efficacy at month 6, control of the disease was achieved in 17 patients, and nine relapses were seen. The one-year Kaplan-Meier survival rate was 56%. Among the 23 patients evaluable at month 12, control of disease was achieved in 13 patients (complete remission without treatment, n = 2; remission with immunosuppressant treatment, n = 8). Therapeutic failure was concluded for 16 patients, eight of whom presented two relapses during the first year of follow-up. CONCLUSION: Despite recent therapeutic recommendations for BP, the prognosis of this disease remains severe. The risk of relapse and mortality rates observed in this study should prompt the development of new therapeutic strategies to supplant superpotent topical CS and reduce the morbidity and mortality associated with the disease.

[Herpetic recurrent upper limb lymphangitis]. / Lymphangite récurrente du membre supérieur d'origine herpétique.

Upper limb lymphangitis often complicates varied wounds on the hand or forearm and improvement is obtained in a few days with adapted antibiotic therapy. A 28-year-old woman presented since few years episodes of lymphangitis of the arm associated with vesicles on an erythematous base, on the palmar face of the first phalanx of the index finger, spontaneous relief within 10 days, without antibiotic therapy. Herpetic origin was confirmed on viral culture. No primary infection neither recurrence was noted. Because of the recurrences, a prophylactic treatment with valaciclovir was instituted. There was no reported recurrence at two years follow-up. Upper limb lymphangitis rarely complicates herpetic whitlow in immunocompetent patient. Clinicians should be aware of viral lymphangitis, which is often overlooked and associated with diagnostic errors and treatment delay.

[The value of photodynamic therapy in the treatment of Bowen's disease]. / Intérêt de la photothérapie dynamique topique dans la prise en charge de la maladie de Bowen.

BACKGROUND: While the standard treatments for Bowen's disease (BD) (surgery, cryotherapy and antimitotic agents) are efficient, they are associated with extensive scarring. In this paper we confirm that photodynamic therapy using topical aminolevulinic acid provides effective treatment for this disease. PATIENTS AND METHODS: Twenty-two patients with a total of 38 cases of BD were included in this retrospective single-centre study between 2001 and 2006. They were treated with photodynamic therapy using topical aminolevulinic acid (Metvix. The study criteria consisted of patient age and gender, site and area of lesions, number of patients with multiple patches of BD and/or large lesions, tolerance of the treatment, clinical response and quality of wound healing at 3, 6 and 12 months. Annual follow-up was conducted for five years. The probability of remission up to 60 months after treatment was determined by means of survival analysis based on the variable-interval actuarial method. RESULTS: Seven men and 15 women of median age: 76 years (interquartile range: [69-82]) with 38 cases of Bowen's diseases were treated with photodynamic therapy. In terms of frequency, lesions were seen predominantly on the lower limbs (N=24) and face (N=10). Other lesions were seen on the trunk or back (N=4). The mean surface area of lesions was 8.62 cm2 (1-96 cm2). Eight patients were presenting multiple patches of BD (> or = three lesions), and large lesions were noted in 11 cases. The most common adverse effect was an immediate burning sensation, described by 32% of patients (n=7). Treatment was effective, with remission being achieved in all patients at 3 months of follow-up. Wound healing was optimal and without atrophy or cosmetic sequelae. The remission rate was 100% at 6 months, 95% at 12 months and 85% at 24 months. DISCUSSION: This open retrospective study confirmed the good efficacy of photodynamic therapy in the treatment of BD in terms of both clinical remission and cosmetic results. It enables easier treatment of large and/or multiple lesions than surgery. It is more suitable for elderly patients than either topical anticancer drugs, which require prolonged compliance, or surgery and cryotherapy, both of which result in slow-healing postoperative wounds. CONCLUSION: Since photodynamic therapy is a very costly therapeutic method, we feel that dynamic phototherapy should be used only for large and/or multifocal lesions or for lesions of the lower limbs in patients with chronic venous insufficiency.

[Abrupt onset of papulovesicular lesions: diagnostic features and outcome]. / Eruptions varioliformes aiguës: aspects diagnostiques et évolutifs.

INTRODUCTION: Abrupt onset of papular lesions, with ulcero necrotic evolution could refers to many dermatitis. Febrile ulceronecrotic Mucha-Habermann disease is an unusual severe form of pityriasis lichenoides and varioliform acuta (PLEVA) characterized with ulceronecrotic eruption potentially associated with high fever and systemic symptoms leading to death. Lymphomatoid papulosis is a recurrent papulonodular eruption with an initial presentation close to PLEVA. While this disorder usually has a benign course, about 10% of the patients develop lymphoproliferative disorders such as CD30+ lymphoma. EXEGESIS: The authors reported an acute form of PLEVA in a young man hospitalized in internal medicine unit with fever and ulcero-necrotic papulo-vesicular lesions. Treatment with tetracycline was successful. They also report a case of lymphomatoïd pustulosis that occurred in a 34 years old woman with an extensive nodulo-pustular eruption characterized by central necrosis and ulceration. Histopathological examination revealed CD30 lymphocytic infiltration leading to diagnosis. CONCLUSION: Theses two dermatosis, uncommon and clinically similar, are both characterized with an unpredictable evolution that to be known by internist.

[Primary cutaneous large B-cell lymphoma in chronic venous leg ulcer]. / Lymphome B primitif à grandes cellules CD20-, CD79a+ apparu sur un ulcère veineux chronique de jambe.

BACKGROUND: Large B-cell lymphoma of the leg in elderly subjects, of intermediate prognosis according to the new EORTC classification, may present as nodular or ulcerated forms. There has been relatively little study of the various etiological hypotheses advanced, including venous insufficiency. We report the case of an elderly man with chronic leg ulcer, recently undergoing modification, in which microscopy revealed large B-cell lymphoma (CD20-). PATIENTS AND METHODS: A 78 year-old man presented chronic ulcer of the right leg of mixed origin with severe venous insufficiency and arteritis. In the previous 2 months, 2 nodules appeared in the centre of the ulcer. Histological examination of a skin biopsy revealed the presence of large B-cell lymphoma and immunohistochemical analysis showed positive anti-CD79a+, CD20- antibody labeling of cells. Staging studies showed only locoregional invasion. Because of the positive CD20- labeling, ZEM chemotherapy (idarubicine, cyclophosphamide, prednisolone) was given, resulting in disappearance of the nodules after four months and preliminary epidermal healing of the ulcer. Several months later, severe infectious complications necessitated amputation. Examination of the excised sample showed no residual tumor. DISCUSSION: Many causal links have been proposed between large B-cell lymphoma of the leg and aetiologies such as infectious agents, Koebner phenomenon and chronic lymphedema, as well as various other vascular factors. A number of hypotheses were proposed in the present case. It may have been leg ulcer cutaneous B-cell lymphoma, or, more likely, development of lymphoma on a chronic mixed ulcer, with the respective roles of vascular disease, local immunosuppression and antigenic stimulation subject to debate.

[Verrucous carcinoma of the lower limbs]. / Carcinomes verruqueux des membres inférieurs.

BACKGROUND: Verrucous carcinoma is a rare, low-grade, slow-growing, well-differentiated squamous cell carcinoma affecting the skin (particularly on the foot) and mucosa. The diagnosis is often delayed. We report a study of twelve cases of verrucous carcinoma of the lower limbs. PATIENTS AND METHODS: We retrospectively studied a series of 12 patients (8 women, 4 men) who developed verrucous carcinoma of the lower limbs between 1978 and 2005 and we analyzed their follow-up data. RESULTS: The mean age of patients was 78 years (66-97 years). Eleven patients exhibited verrucous carcinoma in a previous lesion comprising varicose ulcer (5 cases), mixed ulcer (3 cases), burn (2 cases) or traumatic lesion (1 case). The mean time from onset of lesions to diagnosis was 28 years. Nine patients showed locoregional extension (8 bone involvement, 3 lymph node involvement). No visceral metastasis was detected. Three patients received medical treatment that proved ineffective. Two received secondary surgical treatment. Nine patients underwent surgery (6 amputations, 3 local excisions). Four patients were lost to follow-up, 4 died, 3 showed no recurrence and 1 had a chronic unhealed wound after surgery. DISCUSSION: Verrucous carcinoma of the lower limbs is a disease of the elderly, affecting both men and women, and occurring mainly on chronic venous ulcerations. The clinical presentation is evocative although histopathological diagnosis is difficult, particularly in the event of superinfection. Repeated and deep biopsies are needed to avoid delay in diagnosis. Extension is chiefly locoregional and visceral involvement is rare. Medical treatment is ineffective and may even be harmful, with surgery the best option. Regular monitoring is necessary because of the risk of relapse, although verrucous carcinoma does not seem to directly affect patient survival.

[Cutaneous drug reactions induced by glycopeptides]. / Toxidermies induites par les glycopeptides.

Glycopeptides are a class of antibiotics used with a rising frequency because of the increasing number of infections due to Methicillin-resistant staphylococci. The dermatological adverse effect of vancomycin are well-known: "red man syndrome", maculopapular exanthema, etc., with some distinctive features such as Ig A linear dermatosis. Drug eruptions are less common but not insignificant when using teicoplanin, a more recent molecule. A given glycopeptide cannot be considered as an alternative for every patient "allergic" to another, because of cases of cross-reaction and the morbi-mortality of some cutaneous drug reactions. This emphasizes the importance to recognize early clinical signs. In this article, we review the various dermatological adverse drug reactions induced by glycopeptides, and suggest a possible management to clinicians who could be confronted with this problem.

[Topical tacrolimus and resistant skin lesions of dermatomyositis]. / Tacrolimus topique et atteintes cutanées résistantes de la dermatomyosite.

INTRODUCTION: Dermatomyositis is an inflammatory myopathy associated with an increased risk of mortality due to visceral involvement. Cutaneous involvement has no vital impact but considerably affects the quality of life of the patients and can resist to classical therapies. More treatment options are needed. We report here the case of three patients presenting resistant cutaneous lesions of dermatomyositis successfully treated with topical tacrolimus. OBSERVATIONS: A dramatic cure of the lesions of the face and the hands and a moderate response of other areas were observed without adverse effects. CONCLUSION: Tacrolimus is an immunosuppressive agent and topical tacrolimus is used for the treatment of atopic dermatitis and has been occasionally used to treat skin involvement of some systemic inflammatory diseases. Topical tacrolimus seems to be a good therapeutic alternative for resistant skin lesions of dermatomyositis. It could also be proposed as a first intention therapy because of its good tolerance.

[Systemic adverse reactions with ivermectin treatment of scabies]. / Effets secondaires de l'ivermectine utilisée dans le traitement de la gale.

BACKGROUND: Scabies is a common parasitic infestation and is very difficult to eradicate from institutions. Ivermectin is used extensively thanks to its efficacy and ease of use through oral administration; it was approved for the treatment of scabies in humans in 2001 in France. Most of the adverse effects noted with this drug have been seen during treatment of onchocerciasis and other filarial disease, but they are rare in the treatment of scabies. We report side effects with ivermectin in two elderly patients with scabies. CASES REPORT: A 72-year-old man was referred for scabies and was treated with benzyl benzoate (Ascabiol) and ivermectin (200 microg/kg) in a single dose. Two days later, the patient presented abdominal pain and nausea. Laboratory tests revealed cytolysis tests for other causes of hepatitis were negative. Within two weeks, liver function had returned to normal. Hepatitis due to ivermectin was diagnosed. An 86-year-old woman hospitalised for scabies was treated with benzyl benzoate and a single dose of ivermectin (200 microg/kg). She developed sinus tachycardia and asthma 3 days later. Screening for embolic, cardiac and infectious origins was found. Toxicity of ivermectin was suspected. DISCUSSION: Since the introduction of ivermectin for the treatment of scabies, reports of adverse events are rare although this drug can cause cardiac dysfunction and liver disease in other indications. In our cases, the causal relationship with ivermectin is probable and care must be taken, particularly in the elderly, the population in which this drug is probably most widely prescribed.

[Pyogenic granuloma revealing fistula and deep infection: five cases]. / Botriomycomes révélant une fistule et un foyer infectieux profond: cinq cas.

BACKGROUND: Pyogenic granuloma, or botryomycosis, occurring after minor injury or scratching with a septic implement, is a rapidly growing benign inflammatory vascular tumour, often involving the skin or mucous membrane. We report 5 unusual cases of pyogenic granuloma revealing fistula tracking to foreign bodies such as a pace-maker or orthopaedic material, and deep infectious sites with fistula. METHODS: This retrospective study included 5 men of average age 72.2 years over a period of 22 years (between 1981 and 2003). Clinical images were recorded and a diagnosis of botryomycosis was confirmed in all patients by histological analysis. Four patients presented suppuration. The time from initial clinical signs to diagnosis, presence of traumatic events, screening for microscopic organisms, response to systemic antibiotic therapy, recurrence and clinical features of botriomycosis were analysed. RESULTS: All patients presented botryomycosis with fistula and suppuration revealing deep bone infection and in one patient, pace maker infection. Complete resolution of the lesions occurred after excision of foreign material and prolonged systemic antibiotic therapy. CONCLUSION: We report the first series of botryomycosis revealed by fistula and showing deep infectious disease. Pyogenic granuloma is a well-known but rarely reported dermatologic condition.
