Keratoacanthoma (KA) is a benign but often rapidly growing skin tumor that resembles squamous cell carcinoma (SCC). It is typically considered a low-grade, well-differentiated form of SCC. Although it generally has a good prognosis and may resolve on its own, keratoacanthomas can be challenging to distinguish from squamous cell carcinomas, which can be malignant.
Keratoacanthoma (KA) is a benign, rapidly growing skin tumor that resembles squamous cell carcinoma. It often regresses spontaneously but can cause significant cosmetic concern or lead to scarring. Treatment typically involves excision or curettage, and the lesion's potential to transform into SCC makes a biopsy critical. Sun protection and regular skin checks are key for preventing and monitoring skin tumors like KA.
