Axillary Cystic Lymphangioma in an Adult: A Case Report

Lymphangioma is a congenital malformation of the lymphatic system most often reported in children. Its occurrence in adults is rare. It usually develops in the head, neck, and axillary region. It mimics other conditions, such as cold abscess, simple cyst, hydatid cyst, and hemangioma, on clinical examination. Here, we report a case of cystic lymphangioma in the axillary region of a 32-year-old male. The patient underwent surgical excision and histopathology confirmed cystic lymphangioma. Although it is very rare in adults, cystic lymphangioma should be considered in the differential diagnosis of an axillary mass.
