title: Unusual Osteoblastic Secondary Lesion as Predominant Metastatic Disease Spread in Two Cases of Uterine Leiomyosarcoma.
abstract: Uterine smooth muscle tumors range from benign leiomyomata to low- and high-grade leiomyosarcomas. A leiomyosarcoma is a rare malignant smooth muscle tumor that infrequently metastasizes to the bone. In fact, initial presentation or recurrence as osseous metastases is extremely uncommon in patients with a history of leiomyosarcoma. On imaging, these bone lesions generally appear as lytic foci. The authors report here two cases of osteoblastic bone lesions in leiomyosarcoma of the uterus with predominant metastatic lesions localized in the bone.
