BACKGROUND Focal acantholytic dyskeratosis has been described as an incidental finding and as a clinically distinct lesion. In both situations, a dimorphic histologic pattern is observed: acantholysis and dyskeratosis. Solitary, non-genital lesions displaying such pathology have been difficult to classify. Clinical and pathological characteristics of acantholytic dyskeratotic acanthomas are des...

I read in your Journal, with great interest, the paper by Veiga and coworkers about two cases of clear cell acanthomas located in the nipple area, with histological and immunohistochemical studies. They claim in the discussion, that only five cases had been previously described in the English literature and all affecting Korean women. Four of these cases mimicked chronic eczema. Two new cases w...

Clear cell acanthoma, also known as Degos is a rare benign epithelial skin tumor. Generally, it appears solitary lesion on the lower legs, but in this case, appeared right mammary area near areola, which an exceedingly and exciting finding. This lesion's clinical features revealed elevated dome-shaped plaque with surface lobulations shiny pink color size of 9 mm. Dermoscopy was characteristic b...

Epidermolytic acanthoma (EA) is a benign cutaneous condition. It is characterized by warty or flat-topped, keratotic papules that show epidermolytic hyperkeratosis in histology. EA has been described to occur in various locations, namely the trunk, face, and genitoscrotal area. However, it has not been previously reported to involve the palmar area. To the best of our knowledge, we present the ...

A cutaneous melanocytoma-acanthoma was diagnosed in a 7-year-old intact female mixed breed dog. Grossly, this tumor was a solitary and darkly pigmented nodule located in the face. Histologically, the lesions consisted of melanocytic and epithelial tumor cells. The melanocytic component consisted predominantly of large round-to-polygonal and heavily pigmented melanocytic cells arranged in nests ...

Hodgson, G. A., and Whiteley, H. J. (1970). Brit. J. industr. Med., 27, 160-166. Personal susceptibility to pitch. During the years 1957 to 1963, 59 cases of hyperplastic squamous lesions were referred to us from a local patent fuel works where ovoids were made by fusing coal dust and pitch together by steam heat. We carried out a survey of all the personnel exposed to the pitch hazard and at t...
