Question:

Reportability: Is AIN III reportable if it arises in the perianal skin? See Discussion.

Discussion:

Physical exam states patient has a suspicious area of anal skin. Operative findings show a raised, suspicious lesion in the right perianal region. Our interpretation of the primary site would be skin and therefore not reportable. However, the final diagnosis on the pathology report indicates "AIN III/squamous cell carcinoma with focal areas suspicious for microinvasion. "SINQ #20041056 states that AIN III is reportable.

Answer:

AIN III of the anus or anal canal (C210-C211) is reportable. AIN III (8077) arising in perianal skin (C445) is not reportable.
