[Dermatofibrosarcoma protuberans in children]. / Dermatofibrosarcome protubérant de l'enfant.

Dermatofibrosarcoma protuberans (DFSP) is a relatively rare skin neoplasm. Usually affecting adults, the incidence in children is even less frequent. Through a report of three pediatric cases of DFSP, we describe the particularities of this tumor in children. Three boys aged 8, 9, and 15 years presented with a firm nodular skin lesion of the trunk, varying in size from 1 to 5 cm. No previous trauma event had occurred. Diagnosis was confirmed in all cases by immunohistological study. Surgical excision was performed in all cases. No recurrence was evident during the follow-up period of, respectively, 15, 36, and 49 months. The DFSP is an infiltrative tumor of intermediate malignancy, with a limited potential for metastasis (<5%) but a high rate of local recurrence (≥ 50%). The incidence in children is even less frequent. In children, its seemingly benign clinical appearance may explain delays in diagnosis; the majority of lesions affect the extremities, suggesting a potential role-played by injury. In our observations, however, as in adults, the trunk was the site of occurrence. Despite the uncertain pathogenesis of this tumor, the finding of certain characteristic histopathological features helps establish an accurate diagnosis. As in adults, surgical treatment with large surgical margins remains the best practice for children with DFSP, directly affecting the prognosis.

[Superficial fungal infections. Epidemiologic, clinical and mycologic study over a three year period]. / Les mycoses superficielles. Etude épidémio-clinique et mycologique sur trois ans.

The object of our study is to release the epidemiological, clinical and mycological characteristics of superficial fugal infections. A retrospective study was carried out during three years (1996-1998). Direct microscopy was positive in 86% cases, the culture in 62% cases. Trichophyton rubrum accounts for 85% of the dermatophytic flora. The superficial fugal infections account for 15% of the reasons for consultation in our service. They would touch according to data's of literature 2 to 13% of the general population. Trichophyton rubrum in accordance with the various series published, is the fungi most frequently insulated with variable rates between 46 and 82% of the superficial fungal infections. Any time, Candida albicans is prevalent on the level of the hands.
