Lymphomatoid papulosis and other pseudomalignancies of the skin.
Lymphomatoid papulosis, keratoacanthoma, juvenile melanoma, and atypical fibroxanthoma are clinically benign yet histologically malignant cutaneous disorders which have been designated as pseudomalignancies of the skin. Other disorders which may be classified as pseudomalignant include angiolymphoid hyperplasia with eosinophilia, nodular fasciitis, lymphocytoma cutis, actinic reticuloid and, occasionally, insect bites. A patient with lymphomatoid papulosis is reported and the pseudomalignancies of the skin are briefly reviewed.
