Squamous Cell Carcinoma of the Rectum: Report of Two Cases: Na Rae Kim, Dong Hae Chung, Jeong Heum Baek, Yeon Ho Park, Hee Eun Kyung, Mi Sook Roh, Seung-Yeon Ha; Intest Res 2010;8(2):172-176. Published online December 30, 2010; DOI: https://doi.org/10.5217/ir.2010.8.2.172

Squamous cell carcinoma of the rectum is extremely rare. Herein we report two cases of rectal squamous cell carcinoma. Case 1 was a 44-year-old Korean female presenting with abdominal pain and rectal bleeding for 3 months before her hospital visit. A colonoscopic examination revealed an ulcerated rectal mass 8 cm proximal to the anal verge. Chemoradiotherapy was administered following Hartmann's procedure in case 1. The patient remained alive during 19 months of follow up. Case 2 was a 43-year-old Korean female who had severe constipation for 2 months. A barium enema and computed tomography of the pelvis showed a rectal mass adherent to the sacrum. Based on the results of a colonoscopic biopsy, a diverting colostomy was performed in case 2, with no further treatment. The pathologic findings showed that both tumors were composed of oval-shaped cells with abundant eosinophilic cytoplasm and intercellular bridges with keratin pearls, and thus were diagnosed as well-differentiated squamous cell carcinoma. Neither of the cases showed evidence of HPV infection. The pathogenesis of rectal squamous cell carcinoma has not been clarified. Herein we report two cases of rectal squamous cell carcinoma and briefly discuss the possible histogenesis. (Intest Res 2010;8:172-176)
