Lymphatic malformations: formerly known as lymphangiomas. A rare case of two breast masses in different locations mimicking breast carcinomas

Lymphatic malformations are benign disorders of the lymphatic system and represent a rare diagnosis in adulthood, particularly when involving the breast. This report describes the case of a 64-year-old patient referred to our service with two suspicious masses located in different areas of right breast. Imaging studies reinforced the suspicion of malignancy, and further investigation was conducted with an ultrasound-guided core needle biopsy, which confirmed the diagnosis of lymphatic malformation. As illustrated in this report, although lymphatic malformation may present with imaging findings, histopathological evaluation is often required to exclude malignancy before complete surgical excision. Therefore, lymphatic malformation should be considered as a potential differential diagnosis in the investigation of breast masses suspicious for breast cancer.
