Leiomyoma shows various diagnostic images, often making it difficult to differentiate from leiomyosarcoma. Recently, the utility of elastography has been reported for the differentiation of superficial tumors. We attempted to diagnose two cases of uterine smooth muscle tumors by elastography. One case was strongly suspected of leiomyosarcoma, and the other case had been diagnosed with leiomyoma...

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. ...

Leiomyosarcoma of inferior vena cava is a rare malignant mesenchymal tumor of the venous system that typically occurs in adulthood. Correct and early recognition of leiomyosarcoma is very important, because a complete resection of the tumor (with occasionally chemioor radiotherapy) can lead to prolonged survival. We report a case of a 54-year-old man suffering from the leiomyosarcoma of inferio...

Primary sarcomas of the pancreas are extremely rare, accounting for 0.1% of malignant pancreatic (non-islet) neoplasms. Pancreatic leiomyosarcoma is a highly aggressive malignancy that spreads in a similar manner to gastric leiomyosarcoma, i.e., by adjacent organ invasion, hematogenous spread, and lymph node metastasis. These tumors are large at the time of diagnosis and are usually found at an...

Leiomyosarcoma is a malignant mesenchymal tumor originating from smooth muscle cells, which most frequently develops in the myometrium and in the gastro-intestinal tract. Reviewing the international literature, radiation-induced sarcoma arise in 0.035 to 0.2% of all irradiated patients. Especially in the head and neck region, radiation-induced leiomyosarcoma is an extremely rare lesion. The aut...

Introduction: Leiomyosarcoma of the inferior vena cava is a rare tumor that is hard to diagnose because there are no definitive symptoms. Case Report: A 72-year-old Japanese female presented with edema in both legs. Enhanced computed tomography scan of the abdomen revealed a heterogeneous tumor measuring 10×11×15 cm, which exerted pressure on the inferior vena cava. We preoperatively diagnosed ...

[email protected] Introduction Leiomyosarcoma is a rare sarcoma that usually originates in the retroperitoneum, thus often occurring in the uterus. It more rarely originates intramuscularly in the peripheral somatic soft tissue. Myxoid leiomyosarcoma, in which the myxoid stroma occupies more than 50% of the tissues, is also rarely reported as the myxoid variant of leiomyosarcoma. The pre...

UNLABELLED We report a 43-year-old female with the underlying disease of retroperitoneal leiomyosarcoma and initial presentation of ST elevation myocardial infarction. Coronary angiography showed an absence of coronary artery stenosis and a huge, ill-defined cardiac mass which was fed by both the left anterior descending artery and the right coronary artery. Coronary blood flow was obviously sh...

Gynecologic leiomyosarcoma are uncommon malignancies. Although pulmonary metastases are frequent complications, endobronchial metastases are rare. We report 1 case of gynecologic leiomyosarcoma with endobronchial metastases, along with a review of the topic and bronchoscopic image of this uncommon phenomenon.

Leiomyosarcoma involving the larynx is extremely rare and may be difficult to diagnose. Likewise, because of the rarity of this lesion, little information exists with regard to long-term follow-up or optimal management. Reported here is a review of the literature and a case report of a patient with leiomyosarcoma of the larynx treated by surgery alone with 5 years of follow-up.
