Melanocytes in clear cell acanthoma.

The presence of melanocytes in 11 clear cell acanthoma cases was investigated by silver impregnation. Melanocytes were always present, their density showing great variability from case to case and within each individual neoplasm. The possible existence of a pigmented counterpart to clear cell acanthoma is discussed.

[The Lupus Band Test and serology of lupus erythematosus. Our experience].

The Authors studied, from 1986 to 1988, 84 patients (24 men and 60 women, in an age group that went from 13 to 75 years, with an average of 42 years) in whom DLE was diagnosed. In these patients, a direct immunofluorescent assay was carried out on the affected skin, on the non-affected photoexposed skin, and on the non-affected non-photoexposed skin: furthermore, the serum of these patients was tested for the presence of antinuclear antibodies (ANA), antibodies to extractable nuclear antigens (anti-ENA), and antibodies to double-stranded DNA (anti-DNA). In the study, a significant correlation between the presence of ANA and entity of cutaneous involvement at the Lupus Band Test was found. Furthermore, it was noticed that anti-ENA and/or anti-nDNA tend to be present in association to a positive Lupus Band Test in all 3 biopsied tissues.

[Lichen striatus: a clinical and histological study of 8 cases].

The authors describe eight patients with Lichen Striatus: history, clinical description and pathologic findings are discussed. Particularly, the histologic picture of Lichen Striatus is not uniform and changes, as it seems, with the "oldness" of the lesion.

Porokeratosis palmaris et plantaris disseminata: an unusual clinical presentation.

A 54-year-old man and his son had porokeratoses of the trunk and extremities, predominantly on the palms and soles. Numerous small, slightly depressed, opalescent rings with hyperemic borders were present on the oral mucosa. The spectrum of porokeratosis palmaris et plantaris disseminata and the differential diagnosis of other types of porokeratosis are discussed.

[Laugier-Hunzicker syndrome. Description of 3 cases].

Three cases of essential melanotic pigmentation of Laugier's oral mucosa are presented and personal clinical and histological aspect discussed. The results have been compared with those of other Authors. To verify the low incidence of this disease, the oral cavities of 1000 patients have been examined. In no case were the symptoms of Laugier's disease observed.

[Eosinophilic folliculitis (Ofuji's disease)].

The authors report a case of recurrent folliculitis occurring in a 31 year old man. Histologic examination revealed an inflammatory cell infiltration composed predominantly of eosinophils. The Authors hypothesize that these features are consistent with a diagnosis of Ofuji disease and review the main characteristics of this rare clinical entity.
