[Epidemio-clinical profile of skin cancer in southern Tunisia]. / Profil epidemio-clinique des cancers cutanes dans le sud Tunisien.

BACKGROUND: Skin cancer (SK) frequency is increasing all over the world. AIM: We report a clinical and epidemiological study of SK in the south of Tunisia through a 1476 cases series. METHOD: On the basis of a retrospective study, we report the clinical and epidemiological data collected from files of patients with skin cancers seen during a 24-year-period (1979-2002). RESULTS: Our series was composed of 1476 patients, with an incidence of 615 cases/year. The mean age was 55 years. Epithelial skin carcinomas were the most common (1288 cases, 87.3%). Basal cell carcinomas were found in 890 patients (69%) and squamous cell carcinomas in 398 (31%). The mean age was 60 years. The phototype III was the most common (52.8%) among these patients. Skin melanomas were found in 71 cases (4.8%). The mean age was 54 years with a female predominance (60.6 %). Kaposi sarcoma was found in 4.5% of patients. The mean age was 64.3% and a male predominance was found (80% of cases). Two patients with Kaposi sarcoma (33%) were HIV positive. Dermatofibrosarcoma protuberans was reported in 2% of patients and skin lymphoma in 1.7%. CONCLUSION: The mean age is relatively low in our series. The increase in the incidence of skin cancers is probably related to the climatic conditions, the ageing of the population and to the changes in the social, economic and cultural aspects in the country. The male predominance is changing toward an equal distribution between both sexes probably in relation to the present similarity in the life style and work conditions.

[Beneficial effects of antimalarials in the treatment of generalized granuloma annular in children]. / Interet des antipaludeens de synthese dans le traitement du granulome annulaire generalise de l'enfant.

Granulma annulare is a polymorphic granulomatous disease of the skin. It has a chronic course and affects mainly children and young adults. We report two cases of generalized granuloma annulare in children successfully treated with antimalarials. Two children, 6 and 12 years of age, without clinical history, presented with multiple granuloma annulare lesions which did not respond to potent topical steroids. Blood glucose level was normal. These lesions responded to small doses of antimalarials. No side effects were noticed. Compared with other drugs, with potential important side effects for children. Small doses of antimalarials might be beneficial in the treatment of generalized granuloma annulare.

[Cutaneous metastasis of Crohn's disease]. / Localisations cutanées métastatiques d'une maladie de Crohn.

INTRODUCTION: Involvement of the skin in Crohn's disease is rare. We report the case of a young woman presenting cutaneous nodules revealing a Crohn's disease. CASE REPORT: R. K. a 19 year old woman was admitted the impatient clinic for a 2 week history of nodular lesions of the extremities. Simultaneously, she had watery diarrhoea and abdominal pain associated with a bad general condition and fever. Skin examination showed ulcerated lesions with a non infiltrated inflammatory bader of the left food and the right calf associated with an abscess of the left forearm. Skin biopsy showed an inflammatory infiltrate of the deep dermis with tuberculoid noncaseating granulomas. Colonoscopy demonstrated multiple ulcers, a "globlestone appearance" of the glow and segmental glitis. Colonoscopy was followed by a peritonitis which made steroid therapy questionable. Meanwhile, the patient underwent a colonostomy and was fed intravenously, the skin lesions resolved. A follow up colonoscopy demonstrated colon polyps, and the biopsy of the colon showed features of colitis and "follicular" duodenitis which was in concordance with the diagnosis of Crohn's disease. COMMENTARIES: Usually, cutaneous lesions in Crohn's disease are consistent with nodules and granulomatous fissures of the grain. Involvement of the mucosa is rare. We report the case of "metastatic" localisation of nodular abscesses in Corhn disease. Improvement of cutaneous lesions might be explained by the nonuse of the digestive track allowed by the parenteral supplementation.

[Kaposi' s sarcoma. A series of 65 cases]. / La maladie de Kaposi. Une série de 65 cas.

Kaposi sarcoma (SK) is characterized by proliferation of vascular and spindle-shaped cells with variable clinical presentations. The association with AIDS modifies the profile of this disease. The pathophysiology seems to be based on the major role HHV-8. The goal of this work was to specify the profile of this disease in our region through a retrospective study of 65 cases of SK over a 23-year period (1981-2003). In our series, the classic form prevailed 163 cases (96.9%)]. One patient had a secondary form due to steroid therapy and another patient had a KS associated with AIDS. A male prevalence was noticed (M/F: 2.8). Cutaneous lesions were dominated by papulo-nodular lesions (90.9%) of the lower limbs (92.3% of the cases). Mucous lesions were present in 15.4% of the cases. Therapeutic abstention was decided in 38.4%. Surgical excision was indicated in 35.4% of cases, radiotherapy in 4.6% of the cases and chemotherapy in 23% of the cases. The classic form of KS is the most frequent in our area; the other forms remaining rare.
