Leiomyosarcoma of the left kidney seen in a 58-year-old man is reported. On April 10, 1982, he complained of left flank pain. He visited our hospital and left solitary renal cyst was suspected. He had been treated as an outpatient, but left flank pain became exacervated. On May 18, he was admitted to our hospital. On June 7, radical nephrectomy was done under the diagnosis of left renal cell carcinoma. At operation, the tumor invased directory to the psoas muscle and abdominal wall, and could not be completely resected. Pathological diagnosis was renal cell carcinoma with sarcomatoid change. On July 1, he was discharged from the hospital. In December, left flank distention appeared and back pain became exacervated. On February 8, 1983, he was readmitted to our hospital. Low density area was found in left psoas muscle by CT scanning and recurrence of renal cell carcinoma was suspected. alpha-Interferon therapy had been done, but tumor increased remarkably and caused ileus. He died on June 14, 1983. The autopsy revealed a child head-sized cystic tumor in the upper retroperitoneal space, a 5 X 5 X 5 cm metastasis of the left lobe of the liver, a 3 X 3 X 4 cm tumor to the left upper lobe with cavity formation and direct invasion into the spleen, diaphragma and gastric serosa. These metastatic lesions were leiomyosarcoma. Retrospectively, the primary tumor of kidney revealed primary leiomyosarcoma of kidney.

Leiomyosarcoma of the kidney is a rare entity with poor prognosis. Among renal sarcomas, it is the most common histologic subtype amounting to 50-60% of all cases. The tumors usually arise from either the renal capsule or smooth muscle tissue in the renal pelvic wall. We describe a case of renal leiomyosarcoma that presented with history of left flank pain. Physical examination was normal. Abdominal ultrasound showed a solid lesion of 38 x 36 mm arising from the left kidney. Intravenous urography showed cut off of both major and minor calyces of the left kidney from its pelvis with a normal right kidney. Exploratory laparotomy revealed a well-encapsulated mass confined to the renal parenchyma for which radical nephrectomy was performed. Histopathology showed a Grade I leiomyosarcoma arising from the renal capsule. Adjuvant chemotherapy and sandwich radiotherapy was given and he is disease free after six and half years of follow up. The rarity of this disease, its severity and poor prognosis, uncommon form of presentation, resulting delay in diagnosis and difficulty in management is highlighted and reported.

Leiomyosarcoma of the kidney is a rare entity, and our understanding of this type of renal sarcomas is limited. A 46-year-old Caucasian male presented with a chief complaint of right flank pain for one month. He came to our facility for an additional opinion regarding the management of his renal mass. Computed tomography (CT) of the abdomen showed an enhancing, heterogeneous right renal mass, consistent with the features of renal cell carcinoma (RCC). Robotic-assisted total nephrectomy of the right kidney revealed a tan mass with central necrosis that involved the upper pole of the kidney. Based on gross specimen observation and immunochemical analysis, the patient was diagnosed with high-grade leiomyosarcoma. While the prognosis is poor, radical nephrectomy remains the treatment of choice. The potential benefits of adjuvant therapy should be discussed with selected patients.

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 of the renal vein is a rare tumor of complex diagnosis. We present a case of renal vein leiomyosarcoma in a patient presented with left flank pain. The patient underwent radical nephrectomy with tumour excision.
