Ischioanal fossa epidermoid cysts are rare epithelial masses. Surgical excision is recommended to prevent recurrence, infection, or malignant transformation, as demonstrated in a recent case report.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Ischioanal fossa epidermoid cysts are uncommon epithelial-origin masses, potentially congenital or trauma-induced.
- These cysts pose risks of enlargement, recurrence, infection, and malignant transformation.
Observation:
- A 62-year-old woman presented with vaginal and perineal discomfort.
- A 7.1-cm cystic mass was identified in the left ischioanal space via physical examination and CT scan.
Findings:
- Pathology confirmed the cystic mass as an epidermoid cyst.
- Transgluteal surgical excision resulted in symptomatic improvement.
Implications:
- Epidermoid cysts should be considered in cases of rectal masses.
- Comprehensive evaluation and surgical management are crucial for optimal patient outcomes.
- Early intervention can prevent complications and malignant changes.
