Abstract
Synchronous anal squamous cell carcinoma with colorectal adenocarcinoma is a very rare and interesting disease entity because these neoplasms are essentially different from each other in terms of their anatomical locations, clinical behaviors, histopathological characteristics and treatment. To date, there have been very few case reports regarding the concurrent occurrence of these two distinct neoplasms. Nonetheless, it is recommended that patients with squamous cell carcinoma of the anus and who are older than 50 years should undergo colonoscopy in order to rule out a synchronous colorectal neoplasm. We recently encountered a 72-year-old woman who presented with synchronous squamous cell carcinoma of the anal canal and adenocarcinoma of the rectosigmoid junction. The patient underwent curative surgical resection for the colorectal adenocarcinoma and chemoradiotherapy for the concurrent anal squamous cell carcinoma. We describe here our clinical experience with this unusual case and we also conduct a short review of relevant literature. (Korean J Gastrointest Endosc 2011;42:28-32)
