Inguinal Dermoid Cyst in a Young Boy with un-descended Testis;

Abstract

 Groin lumps have various differential diagnoses, including hernias and lymphadenopathies. Dermoid cysts, occasionally found on the face or scalp, rarely can occur in the inguinal canal. Dermoid cysts are rare benign lesions in the inguinal canal, though inguinal hernias are more common. Despite their rarity, dermoids should be considered in the differential diagnosis of groin lumps. Ultrasound is the preferred diagnostic tool for dermoid cysts, with 58% sensitivity and 99% specificity. However, misdiagnoses (e.g., intramuscular hematoma) or inconclusive results can occasionally occur. Diagnosing these cysts requireshigh suspiciondue to their rarity in the inguinal region. Clinically, they can mimic common conditions like hernias or lipomas, making diagnosis challenging. Inguinal dermoid cysts are extremely rare, with only 12 documented cases. These congenital cysts contain tissues from at least two germ layers. Timely investigations and preoperative suspicion can prevent intraoperative surprises and help avoid potential complications.
