Abstract
Keratoacanthoma (KA) is a low-grade keratinocytic tumor, usually involving sun-exposed areas. The pathogenesis of KA is not completely understood, although it has been assumed that the lesion derived from the hair follicle and that several chemical and non-chemical factors, including trauma and immunosuppression, could play a pivotal role.A wait-and-see strategy for a single KA is questionable, unless signs of involution are already present.1 Indeed, it is difficult to predict the final size of a KA, because KA can reach several centimeters before involution, sometimes producing disfiguring scar. Surgical excision is still the first choice. However, several other options are available for patients in whom surgical procedure is not possibleFile | Dimensione | Formato | |
