[Skin aging].

The skin aging is the result of the association of seven factors; chronological factor, genetic factors, exposure to ultraviolet rays (photodamage), behaviour factors, endocrinous, catabolics and mechanics factors. The treatment combine sun protection measures, topical treatment, dermatological and surgical techniques (peelings, resurfacing laser, injections of collagen, botulic toxin...). The authors intend to study clinical and anatomy-physiology aspect of skin aging, as well as different treatments.

[Giant cell fibroblastoma associated with Darier-Ferrand dermatofibrosarcoma in an adult].

INTRODUCTION: Giant cell fibroblastoma is a rare mesenchyma tumor of childhood having many similarities with dermatofibrosarcoma protuberans in adults. OBSERVATION: We report the case of a 28-year-old woman presenting a subcutaneous inter-mammary mass associating both tumors. Immunohistochemistry showed an expression of CD 34 only by dermatofibrosarcoma protuberans cells. DISCUSSION: It is important to stress: the rarity of this association, the difficulty to confirm the diagnosis and to establish the links between these two tumors: simple association (as in our case), transformation or recurrence of giant cell fibroblastoma in dermatofibrosarcoma protuberans.

[Oral desensitization to antitubercular agents].

We report a case of hypersensitivity reaction to majors antituberculosis drugs. We have successfully performed oral desensitization to "Rifater *". We present our protocol that we compare to those proposed in the literature.

[Comparative epidemiology of pemphigus in Tunisia and France. Incidence of foliaceus pemphigus in young Tunisian women].

INTRODUCTION: Recent studies have suggested that pemphigus foliaceus is quite frequent in young Tunisian women. In order to confirm this hypothesis, we compared the incidence of pemphigus in general in Tunisia with that in the Ile-de-France region. METHOD: All new cases of pemphigus diagnosed during a 6-year period were reviewed in our dermatology and pathology laboratories. These cases were classed as pemphigus foliaceus or pemphigus vulgaris on the basis of histology reports. RESULTS: In France, the incidence was 1-7 new cases per million per year (95 p. 100 confidence interval 1.4-2.1). Pemphigus vulgaris was diagnosed in 73 p. 100 of the cases with an incidence increasing with age. Sex ratio (F/M) was 1.2. The incidence observed in Tunisia was significantly higher than that observed in France with 6.7 new cases per million per year (95 p. 100 confidence interval 5.8-7.7). Pemphigus foliaceus was more frequent (61 p. 100), the sex ratio (F/M) was 4.1. Incidence was higher in young women, with 20 new cases of pemphigus foliaceus per million per year among women from 25 to 34 years of age. These levels were higher in rural desert areas. No familial cases were observed and only one case occurred in a child. DISCUSSION: These findings confirm the specific epidemiology of pemphigus in Tunisia, which appears to be similar and also different from that in Brazilian pemphigus. As in Brazil, there was a predominance of pemphigus foliaceus in young adults living in rural areas in poor socioeconomic conditions. However in Tunisia the disease predominates significantly in women and there are no familial and rare juvenile cases.

Comparative epidemiology of pemphigus in Tunisia and France: unusual incidence of pemphigus foliaceus in young Tunisian women.

Recent studies have suggested that in Tunisia, pemphigus foliaceus is more frequent in young women than expected. To confirm these findings, we compared the incidence rates of pemphigus in Tunisia as a whole and in a large area of France. New cases of pemphigus were detected retrospectively from dermatology departments and pathology laboratories over a 6-year period and classified as pemphigus vulgaris or foliaceus according to the pathology. In France, the incidence rate was 1.7 cases per million per year (95% confidence interval 1.4 to 2.1). Pemphigus vulgaris accounted for 73% of all cases, incidence increased with age, and the female-to-male sex ratio was 1.2. The incidence rate was significantly higher in Tunisia than in France: 6.7 cases per million per year (95% confidence interval 5.8 to 7.7); pemphigus foliaceus was more frequent (61%), the female-to-male sex ratio was 4.1, and the incidence rate was higher in young women. The incidence rate was 15.5 cases per million per year for pemphigus foliaceus among women aged 25 to 34 years and was even higher in some rural areas. No case was observed among household members or in neonates, and only one case occurred in childhood. Thus, we confirmed that the epidemiology of pemphigus in Tunisia is unusual. High rates of pemphigus foliaceus among young people living in rural areas are reminiscent of Brazilian pemphigus. However, the absence of cases among genetically related household members and during childhood, and the large predominance of women, contrast with Brazilian pemphigus.

[Endo-bronchial lipoma. Apropos of a case].

We report a case of an endobronchial lipoma on a 63 year-old woman, treated surgically. A literature review allows us to show the importance of fiberoptic bronchoscopy and computerized tomography in the diagnosis of this kind of benign tumors. The different aspects of treatment with recent progress represented by endoscopic resection are studied.

[Kaposi's sarcoma and hypereosinophilic syndrome].

The authors report the case of a 73-year-old patient with severe Kaposi's sarcoma associated with an idiopathic hypereosinophilic syndrome. This association has not been reported until today and incites us to report this case.
