A Case of Acral Type Acanthosis Nigricans Associated with Lymphoma / 대한피부과학회지

ABSTRACT

Acanthosis nigricans is a symmetric eruption characterized by a hyperpigmented, velvety cutaneous thickening that can develop on any part of the body, but characteristically affects the flexural area of the body. But many dark-skinned people have velvety hyperkeratosis of the dorsum of the hands and feet, a variant of acanthosis nigricans called acral acanthotic anomaly or acral type acanthosis nigricans. Malignant acanthosis nigricans is associated with a malignant tumor-most commonly an abdominal, and particularly a gastric carcinoma. To our knowledge, this is the first report of acral type acanthosis nigricans associated with non-Hodgkin"s lymphoma.
