Keratoacanthoma on the thigh of a 69 year old white female patient. A keratoacanthoma lesion consists of a localised proliferation of squamous cells that forms a cratered nodule. The nodule grows over several weeks before gradually disappearing. However, the unsightly nodule is often surgically removed as it is clinically indistinguishable from a squamous cell carcinoma (SCC). The cause of keratoacanthoma is unknown, although exposure to sunlight appears to be a factor. For an image of this lesion showing its size see C056/2542. | |
