In this report, we present a case of extremely rare cavernous hemangioma (venous malformation) in the inguinal canal. An 11-year-old boy was brought to our hospital, because of a painless palpable mass in the left inguinal region since infancy. He was diagnosed as having left inguinal hernia. The exploration using an inguinal approach showed a blue hyaline-like mass in the inguinal canal, so we suspected varicocele testis. During the operation, the mass was totally resected, and histopathological analytical results led to the discovery of a cavernous hemangioma. To the best of our knowledge, this is the second reported pediatric case of hemangioma in the inguinal canal. In the case of untypical inguinal hernia, we should consider the differential diagnosis of lesions in the inguinal region, and we must perform ultrasonography tests, medical history investigation, and physical examination. Retrospectively, ultrasonography revealed an enhanced posterior shadow, which is a characteristic finding of hemangioma, and it was considered to be an important finding in untypical inguinal hernia.
