[Tinea capitis: 73 cases observed in Bordeaux (author's transl)].

73 cases of tinea capitis were observed in the "Hôpital des Enfants" in Bordeaux during these last five year. 71 children under 14 years of age and only 2 adults have seen. The dermatophytic spectrum transformation noticed in other parts of Western Europe is also encountered in Bordeaux. 83 p. 100 are affected by zoo-antropophilic dermatophytes, M. canis chiefly in town, T. mentagrophytes, T. verrucosum in rural aeras. The cases are often familial, from an infected animal, but without any interhuman transmission. Only 8 out of 73 cases are due to strict antropophilic dermatophytes and are found in newly arrived immigrants from North Africa (T. violaceum, T. schönleini) of from West Africa (M. langeroni, T. ferrugineum, T. soudanense). Not a single case of scholar transmission could be observed. Cure by micronised griseofulvine per os (15 mg/kg/day) associated with local care was effective in all cases.

[Hypomelanosis of the skin and malignant melanoma (author's transl)].

8 patients suffering from malignant melanoma have been found to have various degrees of hypomelanoses of the skin. Depigmentation of the skin and/or hair associated with malignant melanoma may take several forms. Schematically six clinical types are described: - vitiligo-like hypomelanoses distant from cutaneous tumors; - vitiligo-like depigmentation associated with uveitis (incomplete Vogt-Koyanagi); - hypomelanoses in the primary tumor and/or its metastases; - "halo melanoma" in which the hypomelanoses encircles the primary tumor and/or its metastases; - halo nevi around preexisting benign nevocellular nevi; - "non-specific depigmentary phenomen" distant from the primary tumor or its metastases. Histological and ultrastructural studies of the depigmented skin show an absence of melanocytes. The association of hypomelanoses of the skin with malignant melanoma is probably not coincidental. Various hypothesis are discussed as well as the prognostic significance of such an association.

[Regression of primary melanoma with metastases associated with amyopathic dermatomyositis].

BACKGROUND: Dermatomyositis is a rare and serious inflammatory connective tissue disease characterized by a typical cutaneous rash and myopathy. Amyopathic dermatomyositis is a particular form of dermatomyositis involving only cutaneous signs and without myopathy present for over 2 years. PATIENTS AND METHODS: A 48 year-old woman presented with a 3-year history of cutaneous rash without myopathy characteristic of amyopathic dermatomyositis. Clinical examination revealed extensive axillary adenopathy, histological examination of which suggested secondary melanoma. The patient reported a black nevus in the axillary area that had disappeared 1 year earlier. Curettage of the lymph node was negative and the patient was treated with interferon (3M 3 times a week). Regression of the cutaneous signs was noted. DISCUSSION: The data, there have been no other reports of paraneoplastic amyopathic dermatomyositis associated with regression of primary melanoma. The literature contains few reports of dermatomyositis associated with melanoma. Amyopathic dermatomyositis may be associated with malignancy.

[Association of IgA linear dermatitis and non-Hodgkin's malignant lymphoma].

The association between linear IgA dermatosis and neoplasia has been the subject of several publications which suggest that the association is not fortuitous. We report a new case in which a non-Hodgkin's lymphoma was associated with a linear IgA dermatosis and underline the need for full evaluation in search of an associated neoplasia. However, the neoplasia-LAD association is not a true paraneoplastic syndrome since the two pathologies seldom follow a parallel course.

Correlation between bacterial population and axillary and plantar bromidrosis: study of 30 patients.

Although studies on the chemistry of odors are expanding to identify the chemical structures of odorous substances, there are no universal standards as yet to measure odor and intensity of bromidrosis. Clinical evaluation can be made on a subjective scoring from 0 to 3 prior to prescription of an antiseptic soap. In order to appreciate the correlation between the intensity of bromidrosis (BI) and bacterial activity, a study was carried out with both clinical and bacterial assessment in thirty patients with axillary or plantar BI. Odor intensity was evaluated by two physicians using a score from 0 to 3 (i.e. absent, minor, moderate, major), meanwhile bacterial composition and density were assessed before and after 10 days of hygiene using an antiseptic detergent (trichlocarbanilide) provided on the first visit. Baseline count of diphtheroids/cm2 was 35.104 and baseline micrococci average was 32.104/cm2. At the end of the study, the reduction of odor intensity was observed in 20 patients (67%) without any change in sweat production. The clinical improvement correlated with a reduction of both micrococci (70%) or diphtheroids (73%) as compared with initial data. In patients presenting persistant bromidrosis, the bacterial count/cm2 did not significantly decrease and remained above 104 diphtheroids/cm2. Thus, this study suggests that body odor may be at least indirectly correlated to microbia counts with a bacteria threshold of BI ranging around and above 104.

[Papulo-erythematous eruption of neonatal lupus].

INTRODUCTION: Neonatal lupus is rare and cutaneous lesions are usually suggestive of the diagnosis. We describe the case an infant with atypical clinical and histological aspects. CASE REPORT: A female newborn, 6 weeks of life, presented since 3 weeks a papulo-erythematous eruption involving the trunk and the 4 limbs. Cutaneous biopsy showed a dermal infiltrate of mononuclear cells, which corresponded morphologically to lymphocytes. But myelo-monocytic origin was proved by immunostaining. This result could be seen in hematodermia and macrophagic activation syndrome, but we had no clinical sign for these diagnosis. Later, she presented an erythema of the eyelids and erythematous papules of the face leading to suspicion of neonatal lupus. Questioning the mother revealed that she had Raynaud's syndrome since 1995. Antinuclear factors were positive in the patient and her mother, corresponding to antiSSA and antiSSB antibodies. She exhibited cytolytic hepatitis but no congenital heart block. Direct immunofluorescence was negative. The clinical evolution was good with complete clearing of the eruption at the age of 3 months. At 10 months, clinical and biological examinations were normal, with no arguments for haematological disease. DISCUSSION: This observation is original because of the initial papulo-erythematous eruption which is rare in neonatal lupus. Diagnosis was confirmed when specific secondary cutaneous lesions appeared. The biopsy of the first eruption showed a myelo-monocytic infiltrate which has never been described in neonatal lupus. However cutaneous biopsies are rarely performed in neonatal lupus and immunostaining is lacking in the literature.

[Extensive scabies in a baby (author's transl)].

The authors are reporting a new case of widespread scabies in a baby. They take this opportunity to emphasize on the atypical erythematous and excoriated papular rash which sometimes may be vesicular and hyper-keratotic. This widespread eruption may mimic generalised dermatitis, pustular psoriasis and even histiocytosis X. They also underline importancy of longlasting ointment with fluorinated steroid being responsible for this widespread eruption.
