Spontaneous regression in basal cell carcinomas.
Evidence of previous spontaneous regression was found in 6% of 400 randomly selected basal cell carcinomas. A further 14% showed small foci of active regression usually less than 1 high power field in area and characterized by a lymphocytic infiltrate of tumor nests associated with many apoptotic tumor cells. Spontaneous regression of basal cell carcinomas has been paid scant attention in the past.
