FIRST PARAGRAPH: Seborrheic keratosis is a benign proliferation of the epidermis. Many names are applied to this lesion (senile wart, melanoacanthoma), but seborrheic keratosis is the most widely accepted. Considered one of the most common skin lesions, it usually occurs in older patients; there is no predilection for either sex. The lesions appear stuck on the skin, usually on sun-exposed skin. They can be tan, brown, or black. Frequent irritation or friction may cause a papule/nodule to become red and scaly and result in a clinical misdiagnosis. Many variants of seborrheic keratosis are recognized clinically and histologically, but they have no management implications.
