摘要:

This report aims at directing the attention to the rare entity of amelanotic melanoma in situ, as exemplified in a patient who had an amelanotic lentigo maligna 10 years ago and a recurrent lesion of identical clinical and histological (except for pagetoid tumor cells in the epidermis) appearance 4 years ago. Amelanotic melanomas in situ appear as inconspicuous reddish macules, which can hardly be diagnosed or even suspected on clinical grounds.

摘要:

A clinical and histological study was made of a congenital lesion on the knee of a 3-year-old boy showing a peculiar combination of eccrine, pilar and angiomatous structures with the characteristics of organoid nevus. A discussion is made of different questions related to eccrine hemartomas with respect to the clinical picture, the association of other hamartomatous components, the alterations that these induce in other cutaneous structures and their histogenesis.

摘要:

A 42-year-old man with extensive white spongy lesions of the oral mucosa from childhood is reported. Histologic examination of two punch biopsies revealed many foci of epidermolytic hyperkeratosis. Similar lesions were present in one of his two brothers but he refused the biopsy. The problems of differential diagnosis are discussed.
