Abstract

Fibroids, also known as leiomyomas, are the most common benign uterine neoplasms. Although benign, they can undergo malignant transformation. Metastatic breast cancer is rarely identified in a uterine leiomyoma. Herein we are reporting a case of a 52-year postmenopausal patient who presented with rapidly increasing huge abdominal mass with a size that was almost reaching xipisternum. She underwent modified radicalmastectomy for infiltracting intraductalcarrcinoma two years ago and was tamoxifen since then. After investigation like abdominal and Pelvic USG,C.T abdomen suggested Leiomyosarcoma and subtotal hysterectomy was done due to technical difficulty. Pathological analysis revealed metasatic lobular breast carcinoma involving the uterine fundus and leiomyoma. This case is reported for its rarity, as Metastasis of extragenital neoplasms to the uterus is extremely rare and lobular breast cancer metastasizing to a leiomyoma in a patient using tamoxifen.
