BACKGROUND: Liposarcomas are the second most common type of soft tissue sarcomas, 30-50% of these are of myxoid subtype. The aim of this retrospective study was to analyze the local control rate, the metastatic pattern and survival of patients in a consecutive single-institution series. METHODS: From 1983 to 2015, 43 patients with myxoid liposarcoma of the extremities and trunk wall underwent resections. The margin was defined as R0 (wide) or R1 (marginal). Patients were followed for evidence of local recurrence or distant metastasis...

Paratesticular liposarcoma is an infrequent tumor characterized by a growing, painless, inguinal or scrotal mass. Only about 200 cases have been reported as of yet in literature, however there are a few cases regarding giant paratesticular liposarcoma measuring over 10 cm. The disease may be commonly misdiagnosed prior to operation. Improper treatment tends to lead to local recurrence and distant metastasis. The current report presents a case of a 51-year-old patient with a large, painless right scrotum. Magnetic resonance imaging revealed a 7...

Retroperitoneal pleomorphic liposarcoma (RPLS) is the least common but the most aggressive subtype of liposarcoma. We herein report a case of tumor embolism (TE) to the inferior vena cava (IVC) and pulmonary arteries in a 54 years old woman with RPLS. The case suggests that fusion fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) can accurately detect occult TE. It also illustrates the usefulness of computed tomography (CT) and high18 F-FDG uptake by PET/CT imaging for diagnosing such findings as filling defect in the veins and beaded pulmonary arteries as TE...

BACKGROUND: Retroperitoneal or mesenteric primary liposarcoma is a malignant neoplasia whose prognosis depends on the biological variants, the radical resection surgery and the histological subtypes, as well as on local and remote recurrences. Liposarcoma is the most common variant of this tumour among tumours of soft retroperitoneal tissue. The purpose of this study is to evaluate whether the treatment of this disease, carried out at the Ivrea Hospital for urgent reasons, may be considered in line with the experience of high-volume Centres...

Liposarcoma of the spermatic cord is a rare disease and often mistakenly diagnosed as inguinal hernia, hydrocele, and lipoma. We report the case of a 58-year-old man who presented with persistent discomfort and swelling on the left inguinal region. He was diagnosed with left scrotum lipoma when he was 12 years old. He underwent high orchiectomy and wide resection of the inguinal tumor. Histopathological examination revealed a well-differentiated liposarcoma of the spermatic cord with negative resection margin and scrotum lipoma...

We report a first case of paraneoplastic human chorionic gonadotropin (HCG) production in a dedifferentiated liposarcoma with rhabdosarcomatous differentiation in an 83-year-old man with a retroperitoneal mass, unilateral scrotal enlargement, and a serum HCG level of 843 IU/L. Core biopsy of the retroperitoneal mass revealed rhabdomyosarcoma. Orchiectomy revealed a paratesticular dedifferentiated liposarcoma with rhabdosarcomatous differentiation. Fluorescence in situ hybridization analysis performed on both the retroperitoneal and paratesticular masses revealed amplification of MDM2...

First, patients may always develop a second severe illness, even a second cancer. Second, things are not always as they are expected to be. So, careful diagnosis is mandatory. Third, morphology is very important, but sometimes misleading. Always be aware of morphological variants!

BACKGROUND: Reported rates of the incidence of lymph node metastasis in soft tissue sarcoma vary considerably. Many are based on single-institution series and small patient populations. Certain sarcoma subtypes, including synovial sarcoma, have been associated with a higher risk of lymph node involvement. Most single centers have insufficient numbers of patients to assess lymph node metastasis accurately, but larger national databases may allow a more accurate estimation. QUESTIONS/PURPOSES: We queried a large national database and asked the following questions: (1) What proportion of patients with soft tissue sarcoma have lymph node metastasis and distant metastasis? (2) What histologic subtypes are associated with increased risk of nodal metastasis? (3) What is the impact of lymph node metastases and histologic subtype on survival? (4) Does lymph node excision improve survival of patients with soft tissue sarcoma? METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program is a national database that covers a geographic cross-section representing approximately 28% of the US population across demographic groups...

CONTEXT: - Malignant mesothelioma (MM) is a component of the BAP1 tumor predisposition syndrome. Other than in BAP1 familial studies, nonmesothelial neoplasms in individuals with MM has not been comprehensively assessed. OBJECTIVE: - To assess the spectrum and prevalence of nonmesothelial neoplasms in individuals with MM. DESIGN: - Individuals with MM and second neoplasms were identified from a database of 3900 MM cases. The expected prevalence of each type of neoplasm was calculated and compared with the actual prevalence in the study population using available Surveillance, Epidemiology, and End Results data and other published data...

Renal replacement lipomatosis is a condition characterized by varying degrees of renal parenchymal atrophy and perirenal fibrofatty proliferation secondary to chronic inflammation such as xanthogranulomatous pyelonephritis. In severe cases, imaging findings can be misdiagnosed as retroperitoneal liposarcoma.

PURPOSE: Current evidence regarding salvage resection for recurrent retroperitoneal (RP) sarcomas generally lacks detailed histology-specific analyses, but the aggressiveness of these tumors varies widely by histology. We investigated associations between timing and extent of salvage surgery and survival outcomes in patients with recurrent RP well-differentiated liposarcoma (WDLPS). METHODS: The University of Texas MD Anderson Cancer Center Surgical Oncology sarcoma database was reviewed to identify patients with RP WDLPS who underwent surgical resection for first recurrent disease (salvage surgery) in 1995-2015...

Ectopic cardiac fatty images are not rarely detected incidentally by computed tomography and cardiac magnetic resonance, or by exams focused on the heart as in general thoracic imaging evaluations. A correct interpretation of these findings is essential in order to recognize their normal or pathological meaning, focusing on the eventually associated clinical implications. The development of techniques such as computed tomography and cardiac magnetic resonance allowed a detailed detection and evaluation of adipose tissue within the heart...

Lipomas and lipoblastomas are benign tumors of mesenchymal origin in contrast to liposarcoma that is a malignant tumor. Atypical lipomatous lesion arising from embryonal fat cells is termed as lipoblastoma. In the present case report 9-month-old male presented to us with painless, rapidly progressing mass over back, power was normal in all four limbs, fine needle aspiration cytology was suggestive of cellular tissue, magnetic resonance imaging suggestive of well-defined enhancing mass in paravertebral location, extending from D3 to D10 vertebrae with intraspinal extension, communicating through neural foramina at level of D7...

AIMS: Extraskeletal osteosarcoma (ESOS) is a sarcoma in the non-skeletal tissue that directly produces neoplastic osteoid or bone. Dedifferentiated liposarcoma (DDLPS) and malignant peripheral nerve sheath tumor (MPNST) are the two most common types of sarcoma that can harbor heterologous osteosarcomatous differentiation. We aimed to determine the potential relationship of ESOS to DDLPS and MPNST. METHODS AND RESULTS: We investigated MDM2 and H3K27me3 status in 19 cases of ESOS, 2 of which contained a low-grade component...

LESSONS LEARNED: Ablation therapy appears to be a reasonably safe and effective approach to obtain a significant treatment-free interval for a subset of patients with limited sites of metastatic disease for which systemic control can be obtained with six cycles of chemotherapy. BACKGROUND: Metastatic sarcoma often becomes resistant to treatment by chemotherapy. There is sometimes prolonged stable disease from active chemotherapy that provides a window of opportunity for an intervention to prolong disease-free survival...

Liposarcoma is the most common soft tissue sarcoma in adults. Predominant locations are the limbs and retroperitoneum. Intra-abdominal liposarcoma represents only 2% of all cases and visceral location is exceptional. Gastric liposarcoma is extremely rare, with fewer than 20 cases reported. The treatment of choice is wide en-bloc surgical resection. If the tumour arises in the area of the cardia, resection involves resection of the proximal stomach as well as the distal oesophagus. Traditional reconstruction with oesophagogastrostomy often leads to troublesome reflux...

Liposarcomas are classified into 4 different subtypes, with the myxoid-round cell variant demonstrating increased morbidity and metastatic potential dependent on cell composition. Unique to sarcomas, the myxoid-round cell liposarcoma is remarkably sensitive to radiation therapy in the pretreatment setting, owing to the tumor morphology and vascular distribution. Herein we report a case of myxoid-round cell liposarcoma within the deep soft tissues of the thigh of an 81-year-old male with excellent neoadjuvant response to radiation...
