Keratoacanthoma is an epithelial proliferative lesion that develops on sun-exposed skin. It is characterized for having three phases, initial rapid growth is followed by a period of stability and finally, a spontaneous regression. The last phase is rarely seen because the gold standard therapy is surgical removal due to the impossibility to differentiate it from squamous cell carcinoma. The “watch and wait policy” should be agreed with the patient and we must inform the possibility of its aggressive behavior. We present two cases that chose to defer therapy and had a spontaneous resolution with regular close follow-ups.
