A case of reticulum cell sarcoma of the rectum encountered in our department was reported. Only a very few cases have been reported in the world literature.
Patient was a 63-year-old male, complaining of anal bleeding. An elastic firm ulcerated tumor was found at the anal canal, part of which was bulging through the anus. Digital and anoscopic examination revealed the upper border of the tumor was approximately 7 cm from the dentate line. Biopsy revealed that the tumor was reticulum cell sarcoma. Fluoroscopical examination was carried out, to rule out the multi-centric lesions. Radical operation, synchronous combined abdominoperineal excision of rectum was performed including the dissection of inguinal and para-ortic lymphnodes. Resected specimen was also probed to be a primary reticulum cell sarcoma of the rectum.
Chemotherapy (1400 mg of Cytoxan and 7 mg of Vincristine) was given postoperatively. The patient is in good health as of 6 months after the surgery.
