[Lymphangioma of the breast: about a case]. / Lymphangiome du sein: à propos d'un cas.

Lymphangioma is a benign lesion of the lymphatic vessels. It is a rare paediatric condition and it is exceptional among adults. It mainly occurs in the neck, armpit and abdomen. It rarely occurs in the breast. We report the case of a 18 year-old female patient seen in consultation for a mass in her left breast, which had evolved over the last 23 months. Management was based on surgery. The patient underwent complete tumor resection. Anatomopathological examination showed lymphangioma of the breast. Patient's evolution was favorable and the patient had a median 10 months follow-up with no recurrences identified.
