[Benign adnexal tumors of late occurrence in verrucoid-sebaceous nevus (Jadassohn). Apropos of 7 cases].

Occurrence of basal cell epithelioma and syringocystadenoma papilliferum on sebaceous nevi is well known. But many other adnexal tumors, such as pilar or sweat gland tumours may also be associated with this dysembryoplasia. Out of 99 cases of verruco-sebaceous nevi we find 12 associated basal cell epitheliomas, 7 syringocystadenomas papilliferum and 6 benign adnexal tumors. Our report is about these 7 cases. All of these tumors appeared in adult-hood and were clinically suggesting the diagnostic of basal cell epithelioma. But, after histopathological examination was performed, they revealed to be 2 nodular hidradenomas, 1 chondroid syringoma, 1 trichilemmoma, 1 apocrine cystadenoma, 1 follicular poroma. Similar data are given by Mehregan and Pinkus in 1965 and Wilson Jones and Heyl in 1970, respectively out of 150 and 140 cases of verruco-sebaceous nevi.

[Phototoxic activity of 5% benzoyl peroxide in man. Use of a new methodology].

In order to conform to the conditions in which a 5% benzoyl peroxide compound is being used, a new methodology has been developed and applied to 24 volunteers: photobiologic tests were performed and UVB irradiation at infra- and supra-MED times of exposure as well as UVA irradiation on usually covered and usually uncovered areas, after single and multiple applications. This double-blind study (vehicle alone and active substance alone) has been carried out in each subject. UVB phototoxicity resulted in the occurrence of an erythema for an infra-MED time of exposure and/or in changes in the erythema as compared to an adjacent control area for the supra-MED time of exposure. This was found in 8 patients (33%), only on repeatedly irradiated areas, but never with the vehicle alone. No UVA phototoxicity was evidenced. This study confirms the possible phototoxic action of benzoyl peroxide after UVB exposure. It emphasizes the usefulness of repeating the applications on both covered and uncovered areas in photosensitivity tests of a substance.

[Wells' syndrome or eosinophilic cellulitis. Apropos of 2 cases. Review of the literature].

In 1971, four cases of a new dermatosis were described by Wells, under the name of recurrent granulomatous dermatitis with eosinophilia. In 1978, eight additional cases were reported by Wells and Smith and three authors suggested a shorter title: eosinophilic cellulitis for this syndrome. Since then, four additional cases were published in the literature. We report here two additional cases. From these eighteen upto now published cases, there is no doubt that this dermatosis, as initially described by Wells, is a distinct entity. Clinical course is characterized by sudden eruption of large infiltrated, itchy and/or painful plaques. Blisters are often associated. During the two or three weeks following the initial rash, the inflammatory aspect disappears. Lesions become indurated, and may resemble morphea. Spontaneous resolution occurs after about six weeks. Recurrences are constantly observed. Histologic features are a striking eosinophilic infiltrate associated with eosinophilic deposits constituting flame figures. Blood eosinophilia is present in most cases. Etiology of this entity remains unknown.
