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.
在随机选取的400例基底细胞癌中，6%有既往自发消退的证据。另外14%显示有小灶性的活动性消退，通常面积小于1个高倍视野，其特征为肿瘤巢有淋巴细胞浸润，并伴有许多凋亡的肿瘤细胞。基底细胞癌的自发消退在过去很少受到关注。
