Cystic Lymphangioma of the Breast in a 4 Year Old: Case Report

Abstract

Cystic lymphangioma, also known as cystic hygroma, is a rare congenital malformation of the lymphatic system characterized by congenital blockage of lymphatic channels or sequestered lymphatic sacs. They are frequently observed in childhood, yet their occurrence in the breast is exceedingly uncommon and is more frequently seen in adults, with only a small number of cases documented in children. We report a case of a 4-year-old female who presented with a large right breast lump which has progressively developed since birth and was diagnosed as mammary cystic lymphangioma after local excision. There was no recurrence of the lesion at the 1 year follow-up.
