Breast hematoma simulate as carcinoma: A case report and a review of the literature

Breast hematoma is common after trauma, surgery, or biopsy. Sometimes there is no history of trauma and hematoma can occur in patients with hematologic diseases or coagulation disorders. Breast hematoma may present mamographically as an ill-defined density or spiculated mass mimicking a carcinoma. In this report, a 48-year old woman who underwent mammography because of a painless palpable node in the right breast is introduced. Mammography revealed an irregular spiculated lesion, 25 mm in diameter, without microcalcifications in the upper inner quadrant of the right breast which seemed to be a malignant tumor. Ultrasonography of the right breast showed a non homogeneous hypoechoic nodule with irregular margins. Surgery and local excision revealed breast hematoma. ‌Breast hematoma must be thought of as a differential diagnosis for a breast mass, regardless of previous trauma, surgery or hematologic disorders. Occasionally, the late squeal of a breast hematoma may resemble a carcinoma with spiculated lesion
