Summary
Smooth muscle tumors in the rectum, such as leiomyosarcoma, are rare. This case study highlights a successful transsacral resection of a rectal leiomyosarcoma with no recurrence after nearly six years.
Area of Science:
- Gastroenterology and Surgical Oncology
Background:
- Rectal smooth muscle tumors, including leiomyosarcoma, represent a rare clinical challenge.
- Early diagnosis and surgical intervention are crucial for managing these uncommon rectal neoplasms.
Observation:
- A 59-year-old male presented with symptoms of defecation difficulty and melena.
- Physical examination identified a walnut-sized, elastic, hard, smooth-surfaced tumor on the left antero-lateral rectal wall.
Findings:
- Needle biopsy and subsequent transsacral resection confirmed the tumor as leiomyosarcoma.
- The patient experienced no recurrence of the rectal leiomyosarcoma at 5 years and 6 months post-surgery, despite foregoing adjuvant therapy.
Implications:
- This case suggests that transsacral resection can be an effective primary treatment for rectal leiomyosarcoma.
- Complete surgical removal may offer a favorable long-term prognosis for rectal leiomyosarcoma, potentially obviating the need for chemotherapy or radiation.
