Summary
This case report details an extremely rare intrarectal ovarian teratoma presenting as a hairy tumor. Surgical removal was successful, highlighting the importance of considering this rare diagnosis for rectal tumors.
Area of Science:
- Gynecologic Oncology
- Gastroenterology
- Surgical Pathology
Background:
- Primary rectal teratomas are exceptionally rare, potentially arising from aberrant germ cells.
- Ovarian tumors can rarely cause rectal fistulas, complicating rectal pathology.
Observation:
- A 54-year-old woman presented with transanal bleeding.
- Endoscopy revealed a hairy-surfaced tumor 15 cm from the anal margin.
- Imaging identified bony tissue within the tumor, and laparotomy showed ovarian fusion to the rectum.
Findings:
- A 5x4 cm ovarian teratoma protruded into the rectal lumen.
- Histology confirmed a teratoma with derivatives from all three germ layers.
- Surgical resection involved left oophorectomy and tumor extraction via the rectal lumen.
Implications:
- Intrarectal ovarian teratoma should be considered in the differential diagnosis of rectal tumors.
- Endoscopic evaluation of hairy rectal tumors can aid diagnosis.
- A straightforward surgical approach yielded satisfactory outcomes.
