Myoid Hamartoma of Breast - A Rare Mesenchymal Lesion

Abstract

Hamartoma is a local malformation resulting from faulty development in an organ. It was first described in breast in 1971 by Arrigoni et al and its occurrence in breast is very rare. This tumor is composed of breast lobules admixed with fibrous tissue and fibroadipose tissue.  Myoid hamartoma, also called as muscular hamartoma , is composed of smooth muscle cells in addition to ducts, lobules, and stroma. Here, we report a case of myoid hamartoma which occurred in a 53year old lady with a lump in the right breast.
