Lipoleiomyomatous hamartoma of breast

We report a case of bilateral massive painful breast enlargement of recent onset in a post-menopausal woman secondary to marked generalized hyperplasia of erector pilorum muscles. The histology of the lesions does not fit into any of the benign tumors of breast and probably corresponds to the mammary hamartoma. The term Lipoleiomyomatous hamartoma is apt to describe the entity. The search into the literature for such an abnormal, sudden presentation in a postmenopausal woman was not fruitful and so we consider this to be a rare case presentation.
