Myoid Hamartoma of the Breast with Synchronous Contralateral Breast Cancer: Report of a Case

Myoid hamartomas of the breast parenchyma are extremely rare, benign breast neoplasms. Only 15 cases of the parenchymal myoid hamartoma of the breast have currently been described in the medical literature written in English. A 46year-old woman presented with a huge right breast myoid hamartoma and synchronous contralateral left periareolar cancer. We discuss the clinical features, the radiologic findings, the pathologic findings and the management of this type of lesion. Surgeons should be aware that myoid hamartoma is a rare benign tumor, but it can be the cause of a palpable mass in the breast.
