Multiple squamous cell carcinomas complicating linear porokeratosis.

Linear porokeratosis is a distinctive variant of porokeratosis with malignant transformation, a known but infrequently reported complication. We report a case of linear porokeratosis on the right leg of a 57-year-old man present since infancy that, over a 2-year period, developed tow squamous cell carcinomas within the lesion. concurrent right inguinal lymphadenopathy was demonstrated on biopsy to be reactive in nature.
