This paper presents a patient successfully treated for leiomyosarcoma of the vena cava, with no recurrence or symptoms on an 8-year follow-up. A 56-year-old woman presented with chronic and progressive periumbilical and right upper abdominal pain. Physical examination and laboratory tests revealed no abnormalities. Computed tomography showed a high-density image inside the vena cava. Cavography showed a filling defect with complete occlusion of the vena cava involving the renal veins and greatly developed collateral circulation through lumbar veins. Laparotomy was performed and a large caval mass involving the renal veins was dissected and resected. Venous reconstruction was undertaken using a 19-mm bovine pericardium prosthesis (Labcor, MG-Brazil) interposed as a substitute to the vena cava, and the renal veins were anastomosed to the side of the graft. Pathologic examination confirmed a leiomyosarcoma with free surgical margins. The postoperative course was uneventful and the patient was discharged on postoperative day 8. The venous flow through the inferior vena became normal, as confirmed by later cavography. This paper presents a case of successfully managed leiomyosarcoma of the vena cava with a thorough review of the literature. The treatment of such patients and the use of bovine pericardium are also discussed.

Leiomyosarcoma of the inferior vena cava is a rare mesenchymal tumor which originates from the smooth muscle cells of the vascular wall. Its radiographic presentation varies from that of intraluminal lesions resulting in obstruction of the inferior vena cava to those of giant retroperitoneal masses extending to the surrounding perivascular tissues although still with minimal intraluminal protrusion. In this report, we present one such case in which a 31-year-old woman had complaints of severe abdominal pain, abdominal distension and vomiting. Computed tomography demonstrated a giant well-defined right-sided retroperitoneal mass extending from the subhepatic region down to the pelvis. She was operated on and the tumor was discovered to be attached to the wall of the inferior vena cava with a peduncle, a leiomyosarcoma being proven histologically. CT features of this rare tumor are presented in this report.

The Authors report a rare case of retroperitoneal leiomyosarcoma in a 80 years woman with respiratory symptoms and right abdominal pain. A large neoplasm occupied the right abdomen, looking asymmetric. Upper abdominal CT showed a retroperitoneal neoplasm close to right kidney, liver, aponeurosis of right oblique muscles, producing a left-side dislocation of the intraabdominal organs. A surgical "en bloc" resection of the neoplasm was performed; neoplasm was plurilobed and capsulated. The histologic examination confirmed the diagnosis of leiomyosarcoma. The best treatment of these neoplasms is surgery, that in the last years has drawn advantage from more sensible and specific diagnostic procedures, which show a more radical surgical option. Though metastases are occasional, local recurrences can be taken into consideration and, after a careful tumoral re-staging, they can be resected once more. Therefore, a careful follow-up is necessary on the basis of neoplastic grading, extension and involvement of the closer structures.

Inflammatory leiomyosarcoma, a rare entity first described in 1995, has been characterized by smooth muscle differentiation, a near-haploid karyotype, and a surprisingly good prognosis. The morphology is similar to that of conventional leiomyosarcoma admixed with a chronic inflammatory infiltrate. Thus far, only 15 cases have been reported in the English language literature. We report the clinical and pathological features of 3 additional cases of inflammatory leiomyosarcoma. Two women (ages 64 and 25, respectively) and 1 man (age 32) presented with a thigh, ovary, and lung mass, respectively. Inflammatory symptoms, such as anorexia, fever, night sweats, abdominal pain, and diarrhea, coincided with the thigh and ovarian primaries. Immunohistochemical studies revealed diffuse positivity for desmin and poor expression for other smooth muscle and skeletal muscle markers (muscle-specific actin [0/3], alpha-smooth muscle actin 1/3 [focal], calponin [1/3], caldesmon [0/3], and myogenin [0/3]). CD68 was diffusely positive in both the histiocytes and spindle cell component in all cases. Ultrastructural evaluation of 1 case (lung primary) lacked definitive smooth muscle differentiation. Cytogenetic analysis in 1 of 2 cases that were karyotyped, identified a near-haploid karyotype, which has been reported in other cases of inflammatory leiomyosarcoma. The other case showed 2 clonal populations of cells with interstitial deletions of the short arm of chromosome 8 and the long arm of chromosome 9, respectively. The case without cytogenetic data was intimately associated with an ovarian mature teratoma. These data also suggest that inflammatory leiomyosarcoma may lack smooth muscle differentiation, characterized by diffuse immunoreactivity for desmin but lack of immunoreactivity for alpha-smooth muscle actin, calponin, and caldesmon. In addition, 2 of the 3 cases developed distant metastases to the lungs, which suggests that these lesions may have a worse prognosis than previously believed.

Leiomyosarcoma of the inferior vena cava (IVC) is a rare lesion with less than 300 cases reported. Optimal management and long-term outcomes are not well described. From August 1984 to June 2004, eight patients with leiomyosarcoma of the IVC were treated at our institution. Clinical and pathologic data, surgical management, and outcomes were assessed. Eight cases were identified (4 males) with a median age of 52 (range 29-66). Presenting symptoms included abdominal pain (n = 5, 63%), lower extremity edema (n = 2, 25%), and palpable mass (n = 2, 25%). Tumor location was between the renal and iliac veins (low) (n = 4, 50%), between the hepatic and renal veins (middle) (n = 3, 38%), and above the hepatic veins with right atrial extension (high) (n = 1, 12%). Two patients with preoperative IVC occlusion were managed with tumor excision and IVC ligation. Three patients had primary repair of the IVC after tumor excision. A polytetrafluorothylene (PTFE) tube graft was used for IVC reconstruction in three cases. There was no postoperative mortality. Postoperative morbidity included deep venous thrombosis (DVT) (n = 1), lower extremity edema (mild n = 1; moderate n = 1), GI bleed (n = 1), and chronic renal insufficiency (n = 1). One patient is currently receiving adjuvant chemotherapy. Four patients received chemotherapy after recurrence, and one received palliative radiation therapy as well. Median survival to this point was 60 months with a median follow-up of 39 months. The 5-year overall survival and disease-free survival was 31 per cent for both (CI 0.1-1.0). The type of IVC reconstruction had no effect on survival (P = 0.22). Recurrence was discovered in four patients (50%) at a median time of 14 months. Resection of leiomyosarcoma of the IVC should be attempted whenever feasible. The management of the IVC can be managed with primary repair, ligation, or prosthetic graft. Long-term survival is possible if complete resection can be achieved.

We describe 3 cases of leiomyosarcoma of the inferior vena cava (IVC) and review the literature describing clinicopathologic features of 211 cases and the outcome. Of these, 74% of the cases affected women with median age of 52 years. The most common symptoms were abdominal pain or mass (57%), Budd-Chiari syndrome (17%), and deep vein thrombosis (4%). The most frequent site of tumor origin is the middle segment of the IVC (33%). Tumor size ranged from 2 to 38 cm (mean, 12 cm). Of the tumors with an assigned grade, 46% were high grade, 17% were intermediate grade, and 36% were low grade. Of all patients, 47% underwent complete resection, 24% had complete resection with preoperative or postoperative chemotherapy and/or radiation, and 5% had palliative surgery. Tumor recurrence occurred in 40% of the patients (11% had local recurrence and 29% had metastasis). Perioperative mortality occurred in 4% of the cases. Of those patients who died, 42% died of the disease, 2% died of other causes, 26% were alive and free of the disease, 14% were alive with recurrent disease, and 11% were lost to follow-up. Tumors involving level 2 of the IVC have the best prognosis and tumors of level 1 have the worse prognosis. Although there is no standardized criteria for the grading of extrauterine leiomyosarcoma, we propose to grade based on mitotic activity as follows: high grade, 10 or more mitoses per 10 high-power field (HPF); intermediate grade, 5 to 9 mitoses per 10 HPF; and low grade, 1 to 4 mitoses per 10 HPF.

A 70-year-old woman with postmenopausal blood loss proved to have a stage-IV high-grade endometrial stromal sarcoma; 9 months after resection the patient was well. In a 53-year-old woman with symptoms of neurological deficit and weight loss accompanying an increase in abdominal girth and postmenopausal vaginal blood loss a high-grade leiomyosarcoma at stage IV was diagnosed. Despite treatment the neurological symptoms worsened and the patient died within 2 months of diagnosis. Another woman, aged 53, with abdominal pain but no blood loss proved to have a high-grade leiomyosarcoma at stage 1. Nine months after resection and radiotherapy the patient was well. The incidence of carcinomas of the uterus in The Netherlands is on average 113 women per year. They manifest themselves in different ways which can sometimes be misleading. The most common symptom is vaginal bleeding, in combination with abdominal pain or a pelvic mass. The only curative therapy is surgical excision. The 5-year survival rate is 50% in tumours confined to the uterus as opposed to 20% in those that spread further.

Leiomyosarcoma of the inferior vena cava (IVC) is an extremely rare entity. We present the case of a 62-year-old woman who was found to have a large right upper quadrant mass upon examination by her primary care physician in evaluation for diffuse abdominal pain accompanied by anorexia and weight loss. A computed tomographic scan and magnetic resonance imaging demonstrated a 13-cm retroperitoneal lesion that appeared to stem from the right kidney and yielded a tumor thrombus up to the level of the hepatic venous confluence. The patient underwent a right radical nephrectomy and IVC thrombectomy for treatment of a presumed renal cell carcinoma. Instead, pathology revealed the tumor to be a leiomyosarcoma of the IVC. We document this unusual presentation of an extremely rare tumor entity.
