We report the case of a 29-year-old male who presented to us with hematuria, dysuria and bilateral flank pain. On evaluation, the patient was found to have primary pleomorphic undifferentiated sarcoma of bladder with calcified pulmonary metastasis, confirmed with computerized tomography scan and immunohistochemistry.

Liposarcoma is the second most common type of soft tissue sarcoma, but pleomorphic liposarcoma is the least common subtype. We present the case of a 42-year-old man who had experienced intermittent left flank pain for a month. A large soft-tissue mass was detected by ultrasonography in a local clinic, and he was referred for further evaluation. Positron emission tomography/computed tomography (PET/CT) with F-18 fluoro-2-deoxy-D-glucose (F-18 FDG) showed intense uptake in the retroperitoneal mass, which mimicked an adrenal cancer. The patient underwent left radical nephroadrenalectomy, and the tumor was revealed to be a pleomorphic liposarcoma upon pathological examination. When there is a large retroperitoneal mass with intense F-18 FDG activity, the possibility of a pleomorphic liposarcoma should be considered.

A 37-year-old woman was referred to our institution for further management of a mass lesion located in the thoracic cavity. The mass had grown by more than 10 cm over the course of a year and was initially considered to be a scar from previous pulmonary tuberculosis at another hospital. The patient had complained of left-sided flank pain for a year and experienced dyspnea for one month. Chest radiography and chest computed tomography revealed an irregular-shaped mass in the left mid to lower pleural cavity. The mass was widely excised through left thoracotomy. Pathologic examination of the biopsy specimen revealed a malignant spindle cell tumor, which consisted of components of osteosarcoma, pleomorphic sarcoma, and leiomyosarcoma. The patient underwent adjuvant chemotherapy and has been doing well without any evidence of recurrence for 14 months.

The prognostic factors of retroperitoneal liposarcoma have yet to be clearly determined due to its rarity, whereas the prognostic value of symptoms at diagnosis has never been evaluated to date. In this context, we reviewed 24 consecutive patients with primary retroperitoneal liposarcoma who underwent surgical resection with curative intent at our institution. The Kaplan-Meier analysis and the log-rank test were used to estimate progression-free survival (PFS; primary endpoint) and sarcoma-specific survival (SSS; secondary endpoint). The effect of various clinicopathological factors, including symptoms at diagnosis, on these two endpoints was assessed with a Cox proportional hazards model. During the study period, 11 patients (45.8%) developed recurrence after the initial surgery and 8 (33.3%) succumbed to retroperitoneal liposarcoma, with a median follow-up of 64 months. A total of 16 patients (66.7%) had symptoms at diagnosis, while the remaining 8 (33.3%) were diagnosed incidentally. The symptoms were palpability of the tumor (n=8); abdominal pain/fullness (n=3); flank pain/fullness (n=2); lower extremity pain (n=1); testicular pain due to varicocele (n=1); and discomfort on urination (n=1). Patients with symptoms at diagnosis were significantly more likely to develop recurrence (log-rank test, P=0.0196) and were also more likely to succumb to sarcoma (P=0.0778) compared with asymptomatic patients. On the multivariate analysis, symptoms at diagnosis and dedifferentiated components were independent predictors of poor PFS, while positive surgical margins were predictors of poor SSS. Given that symptoms at diagnosis are easily accessible for physicians, they may prove to be useful additional prognostic factors for primary retroperitoneal liposarcoma.

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.

Renal LGFMS is an extremely rare tumor. So far, only four cases have been reported in literature. LGFMS are indolent tumor with distinctive histopathological features with potential for late recurrences and metastasis. The diagnosis is made on histopathological examination and supported by immunohistochemical analysis. A 35-year-old young male was presented with flank pain and lump and diagnosed as low-grade fibromyxoid sarcoma after surgery on immunohistochemical analysis. This is the fifth case of renal LGFMS and we presented the review of literature. Radical surgery remains the primary treatment modality. Long follow-up is mandatory.
