The case of a woman who had had a perianal sinus tract for nine years, in whom squamous-cell carcinoma arose in the sinus tract, is presented. We believe that long-standing perianal sinus tracts should be examined carefully for tumor development. In suspected cases, a biopsy specimen should be obtained from the central part of the lesion.
本文报告一例患有肛周窦道9年的女性病例，该患者的窦道内发生了鳞状细胞癌。我们认为，对于长期存在的肛周窦道，应仔细检查是否有肿瘤发生。在疑似病例中，应从病变的中央部位获取活检标本。
