A case of rectal carcinoid with extensive sacral breakage
The Japanese Journal of Surgery
|July 1, 1990
Summary
A rare carcinoid tumor invading the sacrum was surgically removed. Despite extensive lymph node metastasis, the patient shows no recurrence after two years, suggesting potential for successful treatment of this retrorectal malignancy.
Area of Science:
- Surgical Oncology
- Gastroenterology
- Pathology
Background:
- Retrorectal tumors are rare and can present diagnostic and therapeutic challenges.
- Carcinoid tumors, typically of neuroendocrine origin, exhibit variable behavior.
- Sacral invasion by rectal tumors necessitates complex surgical approaches.
Observation:
- A 48-year-old female presented with a massive retrorectal tumor infiltrating the sacrum.
- The tumor was identified as a submucosal lesion on the posterior rectal wall.
- Abdominosacral resection with partial sacrectomy was performed.
Findings:
- Postoperative examination confirmed the tumor as a carcinoid.
- Extensive lymph node metastasis was present.
- No distant metastasis was detected.
Implications:
- This case highlights the possibility of successful surgical management for extensive retrorectal carcinoid tumors invading the sacrum.
- Aggressive surgical resection and thorough staging are crucial despite the tumor's histological classification.
- Long-term surveillance is warranted due to the potential for lymph node metastasis.
