【 摘 要 】

Squamous cell carcinoma (SCC) of the anal canal is a rare malignant neoplasm, and non-invasive squamous intraepithelial neoplastic lesion of the anal canal is referred to as anal squamous intraepithelial neoplasia (ASIN), which is considered as a precursor lesion of invasive SCC [1]. Most cases of ASIN and SCC of the anal canal are associated with human papilloma virus (HPV) infection, and acquired immunodeficiency syndrome (HIV)-positive individuals are at high risk of development of ASIN and SCC of the anal canal [1].
