Abstract
Lymphangioma circumscriptum is a rare vascular malformation that affects the skin and subcutaneous tissues. Surgical removal in treatment; injection of sclerosing agents, ablation with electrocautery, carbon dioxide laser, radiotherapy and cryotherapy can be applied medically. A 19-year-old female patient was admitted to the dermatology outpatient clinic because of bleeding lesions that started 3 years ago and spread gradually between the lower inner quadrant of the right breast and the sternum. Because of the biopsy taken from the lesion, the patient was diagnosed with lymphangioma circumscriptum. The lesion was surgically excised. Lymphangioma circumscriptum, which is generally localized in the oral mucosa, tongue, areas close to the trunk of the lower and upper extremities, inguinal, armpit and chest region, was detected between the right breast inner quadrant and sternum in this study. We believe that our case, which is rarely encountered in terms of location and age of onset, will contribute to the literature in these respects.
