Summary
This study reports three new cases of large rectal leiomyomas exceeding 5 cm. Complete surgical removal is the treatment goal, with advanced techniques considered for larger tumors.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Rectal leiomyomas are rare submucosal tumors.
- Historically, reported cases rarely exceeded 5 cm in diameter.
Observation:
- Three new cases of rectal leiomyomas larger than 5 cm are presented.
- Diagnosis can be challenging, with physical examination and rectoscopy suggesting submucosal rectal tumors.
- Endoendoscopy aids in defining spatial relationships with the urogenital tract and sphincters.
Findings:
- Distinguishing leiomyoma from leiomyosarcoma based on pathology is difficult.
- Prognosis is uncertain due to potential for relapse and limited follow-up data.
- A slow, spontaneous clinical course is possible.
Implications:
- Complete surgical removal is the primary treatment objective for rectal leiomyomas.
- Local excision is suitable for smaller tumors (<5 cm).
- For larger tumors, echo-guided endorectal protectomy, potentially involving sphincter amputation, should be considered.
