We herein present a case of annular basal cell carcinoma (BCC) with spontaneous regression on the right temporal region of a 56-year-old Japanese male. Histopathological examination revealed that the central section had no tumor cells. The sweat glands, follicles, and other cutaneous appendages were also absent. This pattern of spontaneous regression is quite uncommon, and understanding the histopathology may be important for future approaches to BCC.
我们在此报告一例56岁日本男性右侧颞部环状基底细胞癌(BCC)自发消退的病例。组织病理学检查显示,中央部分没有肿瘤细胞。汗腺、毛囊和其他皮肤附属器也不存在。这种自发消退模式相当罕见,了解其组织病理学对于未来BCC的治疗方法可能很重要。
