title: Malignant acanthosis nigricans associated with non-Hodgkin's lymphoma. Report of 2 cases.
abstract: Two cases of malignant acanthosis nigricans associated with non-Hodgkin's lymphoma are presented. A 61-year-old negro male with a diffuse large cell non-Hodgkin's lymphoma presented extensive acanthosis nigricans, pachydermatoglyphy and florid cutaneous papillomatosis. No viral particles were observed by electron microscopic studies of the wart-like lesions. Acanthosis nigricans disappeared under chemotherapy. The second case was a 21-year-old caucasian male with non T non B diffuse large cell non-Hodgkin's lymphoma. Very few cases of acanthosis nigricans associated with non-Hodgkin's lymphoma have been reported in the literature, since to our knowledge these two are only the fourth and fifth. Pachydermatoglyphy and florid cutaneous papillomatosis are markers of malignant acanthosis nigricans.
