Canal of Nuck cyst in adulthood: A rare differential for inguinal masses - A case report.

Abstract

<h4>Introduction</h4>Canal of Nuck defects are rare anomalies of the female genitalia, typically diagnosed in childhood, but may present in adulthood as inguinal masses. These defects result from the incomplete obliteration of the canal of Nuck, which is analogous to the male processus vaginalis, leading to cyst formation or herniation of intra-abdominal contents. The condition is often misdiagnosed due to its nonspecific presentation.<h4>Case presentation</h4>We present a case of a patient with a Nuck canal cyst, initially misdiagnosed as a lipoma. She presented with right groin pain and a palpable mass, which was confirmed to be a canal of Nuck cyst via ultrasound. Surgical excision was performed, followed by histopathological confirmation.<h4>Discussion</h4>This case highlights the importance of considering canal of Nuck defects in the differential diagnosis of inguinal masses in adult females, given the potential for misdiagnosis and delayed treatment. Imaging plays a key role in diagnosis, aiding in distinguishing this condition from other inguinal masses. Early surgical intervention offers favorable outcomes and prevents complications.<h4>Conclusion</h4>Canal of Nuck cysts, although rare, should be included in the differential diagnosis of inguinal masses in adult females. Accurate imaging and timely surgical excision are essential for effective management and positive patient outcomes.
