Cutaneous sclerosing perineurioma of the digits: an uncommon soft-tissue neoplasm. Report of two cases with immunohistochemical analysis

Background:  Cutaneous sclerosing perineurioma is a recently characterized, uncommon tumor composed of perineurial cells, which exhibits immunoreactivity for epithelial membrane antigen (EMA). These lesions occur preferentially in children and young adults and usually develop as dermal or subcutaneous nodules in the hands or palms.

Eruptive lesions in a patient with bone marrow transplantation

A 41‐year‐old man with a diagnosis of chronic myeloid leukemia presented with several elevated, small, soft, yellow papules, disseminated over the face and upper trunk. The cutaneous lesions had developed 5 years after transplantation ( Fig. 1 ).

Congenital atrophic dermatofibrosarcoma protuberans

A 16‐year‐old girl presented with a congenital atrophic plaque on the anterior aspect of her right leg. The lesion had slowly enlarged until she was 9 years of age; subsequently, several tumors appeared on the surface and later became reddish, hot, and mildly painful. Within a few months, all the tumors flattened and involuted. A previous biopsy showed a congenital fibroma. The patient was in good health; the physical examination, chest X‐ray films, and laboratory studies were normal. No history of personal or familial diseases was recorded.
