title: Bilateral myoid hamartoma of breast: an exceptionally rare lesion.
abstract: Breast hamartomas (BH) or Fibroadenolipoma are extremely rare breast lesions. They are benign, focal malformations that resemble a neoplasm in the tissue of its origin. We describe a case of a 48 year old woman with bilateral breast lumps for the past 18 months and 6 months which were gradually increasing in size. FNAC smears revealed only clusters of benign ductal epithelial cells. Lumps were excised and histopathology revealed predominantly stromal smooth muscle bundles (proved by immunohistochemistry) along with scattered intact terminal duct-lobular units, dilated ducts and entrapped islands of mature fibroadipose tissue. A diagnosis of Bilateral Myoid hamartoma of breast was given. To the best of our knowledge till date no case of bilateral MH of breast has been reported in the literature. We report the first case of bilateral MBH highlighting its morpho-immunophenotypic features.
