Comments

A rapidly growing tumor developed on the right forearm of this 54-year-old man over the preceding 2 months. Note the surrounding chronic actinic changes. Keratoacanthoma is rapidly growing benign epithelial neoplasm that simulates squamous cell carcinoma. It is impossible to make a definitive clinical distinction between keratoacanthoma and squamous cell carcinoma.
