Adult-onset cystic hygroma in the axilla in a 44-year old female: A case report

@#This is a case of a 44- year old female presenting with an 18cm x 17cm soft, movable, non-tender mass at the right axilla extending to the lateral aspect of the right breast. Computerized tomographic scan of the chest revealed a lobulated, multi-septated hypodense mass. The patient underwent excision of the right axillary mass and final histopathology revealed cystic lymphangioma. Adult-onset cystic hygroma of the axilla is a rare case, with less than 10 studies documented in PubMed. Total surgical excision remains to be its primary treatment.
