[Mixed dermatophytic infection of the hairy scalp].

A mixed infection induced by Microsporum canis and Trichophyton tonsurans has been observed on the scalp of a 10-year-old girl. Microscopy has shown microsporum-type endo-ectothrix parasitism on some hairs, whereas others exhibited a strictly trichophyton-type endothrix parasitism. This double parasitism was confirmed histologically (PAS coloration), and M. canis and T. tonsurans could be cultured. The infection was eradicated after 5 weeks of treatment with griseofulvin (750 mg/day per os) and local application of 1% Econazol spray solution twice a day.

[Histopathologic study of perioral dermatitis].

38 biopsies of perioral dermatitis have been examined. The following has consistently been observed: follicular hyperkeratosis; vasodilatation and oedema (sometimes very pronounced) of the papillary dermis; perivascular and parafollicular infiltrates consisting predominantly of lymphocytes, histiocytes and polymorphonuclear leucocytes. Occasionally, there have been epithelioid or giant cells, sarcoid-like infiltrates or vasculitis of the leucoclastic type. Demodex folliculorum was observed in only two sections and the follicles that contained them were not inflamed. This histological picture is very similar to that of acne rosacea.

[Is the BK mole syndrome always an autosomal dominant trait?].

After a brief review of the characteristics of familial malignant melanoma, the authors summarize the literature about the BK mole syndrome. The clinical and histological features of this dermatosis are described. Three personal cases are also reported. The latter tend to demonstrate a certain genetic heterogeneity, while in the literature the BK mole syndrome has been described as an autosomal dominant trait.
