Breast Giant Cystic Lymphangioma with An Axillary Origin. A Case Report

Background: Cystic lymphangioma is a rare congenital anomaly that affects children under two years of age. In adults, it´s even more rare, especially in an axillary location. It is related to trauma, infection and has an iatrogenic cause. Case: We report the case of a 26-year-old woman with a history of a left hemithorax hemangioma at age 12, with multiple previous interventions, that at 25 years old, presents sudden growth of the lesion associated with pregnancy. The CT scan ruled out a deep tissue and contralateral breast compromise, so we performed resection with mammoplasty and nipple-areola replantation altogether with the Plastic Surgery department. She was discharged with a closed suction drain. The histopathology conclusion was of cystic lymphangioma and lymph fluid without malignancy data. Conclusions: The diagnosis and treatment of these lesions must be done early, take a multidisciplinary approach and surgical resection is recommended. The MRI imaging is the preferred study of choice.
