説明
Anal margin is an unusual location for squamous cell carcinoma (SCC). On rare occasions, anal margin carcinoma is the cause of pruritus ani.To describe a case of SCC of the anal margin with pruritus ani of long duration.A 52-year-old man had been aware of perianal itching for over 10 years. Examination of the perianal area revealed a reddish, eroded, hard nodule that was 2.0 x 1.5 x 0.3 cm in size located in the 3 o'clock position. The histopathologic diagnosis was well-differentiated SCC. The nodule was totally excised with a 1-cm margin. No recurrence or metastases were observed for 7 months.When pruritus ani does not respond to conservative therapy and when symptoms have existed for a long time, we should suspect the presence of malignancy.
