Leiomyosarcoma of primary vascular origin is a rare primary soft tissue tumour, which arises mainly from the inferior vena cava (IVC). Clinical symptoms depend upon the size and location of the tumour and presents usually with abdominal pain, palpable mass and weight loss. Complete surgical resection with clear surgical margin plays a central therapeutic role. The effect of chemotherapy and radiation therapy remains to be evaluated. We report a 64 year old Chinese female who presented with abdominal mass and pain associated with weight loss and was subsequently diagnosed with inferior vena cava leiomyosarcoma. She underwent successful surgical resection but unfortunately developed recurrence of tumour 12 month post-operative. She was also found to have a duplicated inferior vena cave which allowed reconstitution of venous return from the lower limbs after surgical resection of the IVC tumour. We discuss the surgical treatment and results of leiomyosarcoma of the IVC.

Leiomyosarcoma of the iliac vein is a very uncommon tumor. We report the case of a 55-year-old man with leiomyosarcoma of the left iliac vein. The patient had abdominal pain and hematuria. Abdominal ultrasound and computed tomography scanning demonstrated a well-defined mass in the left inguinal region, probably arising from the left iliac vein. Ultrasound-guided needle-core biopsy was consistent with a malignant growth. The patient was operated on, and a neoplastic multinodular mass attached to the posterolateral wall of the iliac vein was found. The tumor was resected en bloc, and venous reconstruction was undertaken using a saphenous vein segment. The postoperative course was uneventful, and the histologic study of the resected specimen was confirmed microscopically to be a leiomyosarcoma. No signs of recurrence or metastasis were present 29 months after complete surgical resection.

Vascular leiomyosarcomas are rare tumors, arising most frequently from inferior vena cava (IVC). They are mostly seen in sixth decade, with a female predominance. Their diagnosis is often challenging, as patients may present with non-specific complaints such as dyspnea, malaise, weight loss, abdominal pain, or back pain, preceding the diagnosis by several years. Leiomyosarcoma of the IVC most frequently occurs in the middle segment. The final diagnosis can be made by an ultrasound or computed tomography guided biopsy. Because of limited experience with this disease, optimal management of IVC leiomyosarcoma is unknown. Curative surgical resection remains the current treatment of choice for primary leiomyosarcoma of IVC. Neoadjuvant therapy may be given to downsize the tumor and increase resectability rates. Nonetheless, when complete resection is not possible, debulking combined with radiation therapy still provides good palliation. We, hereby, report four cases of this rare entity with emphasis on management.

Leiomyosarcoma of the inferior vena cava is a rare tumor that is usually fatal. The tumor may grow very slowly or occasionally very rapidly, shows extensive local invasion, and metastasizes more frequently than previously believed. Complete surgical resection remains the only potential curative therapeutic option. The aim of this study was to report the clinical experience in the management of a patient with leiomyosarcoma. A 65-year-old woman with a history of vague abdominal pain and leg swelling underwent computed tomography which demonstrated an occlusion of the inferior vena cava. The patient received a complete excision of the tumor without reconstruction and histological analysis confirmed the diagnosis of leiomyosarcoma type 1. At 3 years, the patient is still doing well with minimal leg edema and a contrast-enhanced CT demonstrates no evidence of recurrence locally or in distant sites. Leiomyosarcoma is a rare and aggressive tumor that presents with non-specific symptoms. Computerized tomography with 3-D reconstruction is a useful tool to define the presence and entity of the collateral circulation and therefore to decide on the surgical strategy. Resection probably offers the best opportunity for long-term survival.

Leiomyosarcoma of the inferior vena cava (IVCL) is a rare malignant tumour originating from the smooth muscle cells of the media with intra- or extra-luminal growth. The type of the lesion is further divided into three levels in relation to hepatic and renal veins respectively. The aim of this review was to evaluate the results of surgical treatment of IVCL with special reference to the extent of its histological spread and to analyse the recent literature in order to provide an update on the current concepts of diagnostic and therapeutic management of this entity. IVCL's patients may present with non-specific complaints such as dyspnoea, malaise, weight loss, nausea, vomiting, fever and abdominal pain. Haematogenous metastasis is frequent. At a later stage, IVCL may also spread through lymphatic. Multiple diagnostic imaging techniques have been proposed for accurate preoperative diagnosis, including Doppler ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI), individually or in combination with cavography echocardiography or CT-guided biopsy. Despite recent research on the therapeutic strategies against IVCL, surgical resection appears the only potentially curative approach. Unfortunately, a mere minority of patients is eligible to undergo surgical intervention. In addition, surgical removal of IVCL does not necessarily guarantee patient's long-term survival. Alternative therapies, such as radio- and chemo-therapy often proved insufficient. Debate continues regarding the optimal management of the IVC after tumour resection, with primary repair, ligation and IVC reconstruction all have been utilized with varying success.

Leiomyosarcoma of the vena cava is a rare malignant tumor. A 61-year-old woman was admitted with right upper quadrant abdominal pain. Computed tomography revealed a retrohepatic vena cava tumor originating 2 cm below the confluence of the hepaic veins and ending 2 cm above the renal veins. The tumor was resected with 1 cm clear surgical margins, without requiring liver resection. Polytetrafluoroethylene vascular graft was used for reconstruction of the vena cava. Now 32 months postoperatively, there has been no recurrence or metastasis. Radical resection with negative surgical margins is the best curative therapy for leiomyosarcoma. Polytetrafluoroethylene vascular graft can be used in extensive tumors located at the vena cava.

Leiomyosarcoma (LMS) is a malignant tumor of smooth muscle cells and comprises 5-24% of all soft tissue sarcomas. Although the most frequent symptoms are vaginal bleeding and abdominal pain, the symptoms are generally associated with dimensions and localization of the tumor. The current study presents a case of uterine leiomyosarcoma that metastasized to the rectus abdominis muscle, which has only been previously reported in two cases in the literature. A 57-year-old multigravid patient presented with a palpable mass in her abdomen. The patient's past medical history revealed a hysterectomy performed in another center seven years ago with a postoperative histopathological report of leiomyosarcoma. A myomatous mass was detected, which was localized at the distal part of the right rectus muscle during operation. The mass was completely excised. The case was diagnosed as leiomyosarcoma according to the histopathological findings. Any mass in a skeletal muscle should be suspected to be metastasis in patients with a prior history of aggressive gynecologic malignancy such as LMS.

Leiomyosarcomas (LMSs) originating from the wall of blood vessels are aggressive and rare neoplasms. The current study describes a case of a 52-year-old man who presented with intermittent abdominal pain without weight loss or diarrhea. Computed tomography of the abdomen identified a 4-cm, solid, heterogeneous tumor in the tail of the pancreas, while a hypodense lesion was also noted in the right hepatic lobe. The patient subsequently underwent splenic pedicle tumor resection, splenectomy and liver tumor resection. Notably, immunohistochemical and histological analyses identified LMS, which had originated from the smooth muscle of the splenic vein. Currently available information regarding LMSs of the splenic vein and their management is also discussed, with the aim of improving diagnostic accuracy.

BACKGROUND Leiomyosarcoma is the most common primary malignancy of the inferior vena cava (IVC), and represents approximately 10% of primary retroperitoneal sarcomas. Leiomyosarcoma presents with non-specific symptoms, including abdominal pain or back pain. There is an increased incidence in immunosuppressed individuals. CASE REPORT An unusual presentation of IVC leiomyosarcoma is reported in a 46-year-old female patient infected with human immunodeficiency virus (HIV) who was on highly active antiretroviral therapy (HAART) and who had a normal CD4 count of 934, who presented with back pain. Magnetic resonance imaging (MRI) of the lumbar spine showed a mass of the IVC. Initial computed tomography (CT)-guided biopsy of the IVC mass was non-diagnostic. An IVC filter was inserted, and the patient was discharged home, but 20 days later, she returned to the hospital with worsening right flank pain. Laboratory tests showed acute renal failure, and a repeat CT scan showed IVC thrombus extending 5 cm superiorly. When compared with the previous CT, there was an extension of thrombus into both renal veins. Histopathology of a transjugular needle core biopsy showed a moderately differentiated leiomyosarcoma. The patient was transferred to a multidisciplinary sarcoma center for surgical resection, chemotherapy, and radiation therapy. CONCLUSIONS This report is of a rare case of IVC leiomyosarcoma in a middle-aged HIV-positive woman with a normal CD4 count. Leiomyosarcoma of the IVC is extremely rare, is often detected when advanced, and has a poor prognosis. This case report describes the clinical, imaging, surgical and histopathological findings of leiomyosarcoma of the IVC.

Leiomyosarcoma (LMS) of primary vascular origin is a rare entity with only potentially curative option being complete surgical resection; despite which the prognosis remains dismal. Tumour recurrence is very common, and the benefits of adjuvant therapy are undefined. A 39-year-old woman presented with 6 months' history of abdominal pain, abdominal distension and pedal oedema. On evaluation, she was diagnosed to have chronic Budd-Chiari syndrome (BCS) secondary to a tumour arising from the inferior vena cava (IVC) on evaluation. Her liver decompensation included jaundice, gastrointestinal bleed and ascites. Following a detailed multidisciplinary team discussion, she underwent complete excision of the tumour along with a segment of the IVC with living donor liver transplantation. She remains disease-free 24 months following surgery. This is the first reported case of liver transplantation for IVC LMS causing chronic BCS.
