Summary
Anal gland/duct cyst (AGC) is a rare condition, often asymptomatic. This case highlights the importance of considering AGC in anal canal mass diagnoses and recommends transanal excision for confirmation and treatment.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Pathology
Background:
- Anal gland/duct cyst (AGC) is a rare retention cyst, affecting 0.05% of patients undergoing anal surgery.
- It results from anal duct obstruction leading to fluid accumulation within the anal gland.
Observation:
- A case of AGC was identified in a 66-year-old woman during a routine colonoscopy.
- The patient presented with no specific anal symptoms prior to the discovery.
Findings:
- The anal gland/duct cyst was successfully excised via a transanal approach.
- Histopathological examination of the excised specimen confirmed the diagnosis of AGC.
Implications:
- Colonoscopists should consider AGC in the differential diagnosis of any anal canal mass.
- Prompt recognition and transanal excision are recommended for definitive diagnosis and treatment of AGC, differentiating it from malignancy.
