Summary
Menstrual rectal bleeding, a rare symptom of sigmoid endometriosis, can be challenging to diagnose. Surgical histological examination confirmed the diagnosis in this case, highlighting diagnostic difficulties and therapeutic options.
Area of Science:
- Gastroenterology
- Gynecology
- Pathology
Background:
- Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus.
- Sigmoid endometriosis, though rare, can present with gastrointestinal symptoms.
- Rectal bleeding during menstruation is an uncommon but significant symptom.
Observation:
- A patient presented with recurrent rectal bleeding synchronized with her menstrual cycle.
- Initial diagnostic attempts including biopsy and scanning were inconclusive.
- Surgical excision of the sigmoid lesion allowed for definitive histological diagnosis.
Findings:
- Histological examination confirmed endometriosis of the sigmoid colon.
- The case highlights the diagnostic challenges associated with extragenital endometriosis.
- Incidence, diagnostic difficulties, and current therapeutic strategies were evaluated.
Implications:
- This case underscores the importance of considering endometriosis in patients with cyclical rectal bleeding.
- Improved diagnostic methods are needed for early detection of sigmoid endometriosis.
- Understanding the incidence and therapeutic outcomes can guide clinical management.
