What is it?
Fast-growing tumor that resembles squamouscell carcinoma, from which should be differentiated. In general, it evolves spontaneously to regression and tends to affect more men after 40-50 years of age.
Characteristics and symptoms
Most lesions appear on the face or upper limbs. The lesion is elevated, pink, with smooth edges and with the center occupied by a crusty and hardened mass. The appearance resembles a volcano. The growth is rapid and big lesions can be formed in short time.
Although uncommon, there is a form of multiple keratoacanthoma, when multiple lesions appear simultaneously.
Despite the possibility of spontaneous regression in some months, because of its similarity with squamous cell carcinoma and the possibility of reaching large dimensions, it is recommended that the keratoacanthoma should be treated. If you notice a lesion of rapid and progressive growth, look for a dermatologist as soon as possible for an evaluation.
Treatment of keratoacanthoma is mostly surgical. In patients who can not undergo surgery, other treatments may be used, in order to achieve tumor regression.
