Benign metastasizing leiomyoma is a rare clinical entity that has been described in several previous reports. Although the exact pathophysiology of the disease is unknown, two predominant theories exist: (1) metastasis from an existing leiomyoma (commonly seen with uterine leiomyoma) or (2) multicentric leiomyomatous growths rather than actual metastases. We ...

Inferior vena cava filters are increasingly utilized to prevent pulmonary emboli originating from lower extremity, pelvis, or caval thromboses. Unique indications exist for filter placement in the suprarenal portion of the vena cava. The largest reported experience in suprarenal position has involved the use of the Greenfield filter. Although unique ...

Diffuse esophageal leiomyomatosis is a rare disorder which may be found in association with leiomyomas in other locations or with other disorders. We report two cases in men, one with associated tracheobronchial involvement, which illustrate the value of imaging in differentiating this entity from other causes of dysphagia and in ...

Leiomyoma is one of the rarest solid tumours of the ovary. We report a case of a degenerated ovarian leiomyoma associated with pregnancy. MR findings are identical to those of degenerated uterine leiomyoma and it is difficult to differentiate between them. Ovarian leiomyoma should therefore be included in the differential ...
Pins M R - - 1999
BACKGROUND: Primary cardiac leiomyosarcomas are rare. Isolated reported cases and small series generally describe spindle-celled, high-grade tumors with poor short-term survival; however, the pathologic features of many of these tumors are incompletely documented. The authors report in detail the clinicopathologic features of 2 relatively low-grade epithelioid and spindle-celled primary cardiac ...

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 ...
Gangadharan V P - - 1999
Primary choriocarcinoma of the ovary (PCO) is rare. This can be gestational (GCO) or nongestational (NGCO) in origin. It is difficult to differentiate between CGO and NGCO. NGCO carries a worse prognosis than GCO. We present two cases of metastatic GCO who were treated successfully with combination chemotherapy and are ...
