Unusual findings in the inguinal canal: a report of four cases

Masses in the inguinal canal other than hernias are rare occurrences, and their preoperative diagnosis requires a high index of suspicion. A soft, partly reducible groin mass in a 3-month-old boy proved to be a cystic lymphangioma within the inguinal canal. A 15-month-old female who presented with an irreducible inguinal mass was found to have a neuroblastoma metastasis in the groin. An irreducible groin mass in a 6-year-old female proved to be an inguinal canal epidermal inclusion cyst. A 14-year-old female presented with a painful groin swelling that represented an incarcerated hemorrhagic ovarian cyst. An awareness of the wide spectrum of entities other than the standard bowel, testicle, and ovary in the inguinal canal can help to identify uncommon pathologies preoperatively.
