Tumor to tumor metastasis is a unusual phenomenon. Metastasis of lobular breast carcinoma to the rare benign tumor lipoleiomyoma is an uncommon occurrence. Only one case has been documented in the reviewed literature. Here we present a 40 years old female patient with past history of invasive lobular carcinoma of right breast. The patient came 3 years after mastectomy with abnormal uterine bleeding and abdominal discomfort. Hysterectomy was done and three fibroids were identified of which the smaller two showed features of leiomyoma. The largest fibroid showed histological features of lipoleiomyoma infiltrated by metastatic lobular carcinoma of breast. In patients with advanced lobular carcinoma of breast and suspicious gynecological symptoms, the possibility of uterine metastasis should be included in the postoperative planning. This case is being reported because of its rarity involving two very unusual pathologies.
