title: [A Case of Anal Canal Carcinoma with Inguinal Lymph Node Metastasis Treated with Laparoscopic Abdominoperineal Resection].
abstract: We report a case of anal canal cancer with inguinal lymph node metastasis treated with laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. A 52-year-old woman was diagnosed with anal squamous carcinoma after excision of an anal canal tumor. Further examination revealed right inguinal lymph node metastasis. Chemoradiotherapy was administered but was discontinued because of serious adverse events. We therefore performed laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. The pathological findings revealed residual squamous cell carcinoma at the lymphatic vessels in the rectal wall and lymph nodes, including the right inguinal region. Therapeutic effect of Grade 1a was achieved in spite of interruption of the chemoradiotherapy. She was discharged 17 days after the operation, and no recurrence was observed for 11 months. Radical resection was performed for the anal canal squamous cell carcinoma with the metastasis to the right inguinal lymph node, even after interruption of the chemoradiotherapy.
