We describe a case of mixed liposarcoma of the axilla presenting as a high grade undifferentiated sarcoma with areas of well-differentiated and myxoid liposarcoma. MRI demonstrated a lobulated, septated intermuscular mass with marked heterogeneous gadolinium enhancement. A small focus of the tumor demonstrated fat suppressed signal more characteristic of well-differentiated liposarcoma. Patholo...

Myxoid liposarcoma is a rare form of soft-tissue sarcoma. Although most patients initially respond well to treatment, approximately 21% relapse, highlighting the need for alternative treatments. To identify novel treatment regimens and gain a better understanding of myxoid liposarcoma tumor biology, we screened various candidate and approved targeted therapeutics and chemotherapeutics against m...

Liposarcoma is one of the most common soft-tissue sarcomas in adults, but head and neck are rarely involved, especially regions of the larynx and hypopharynx. According to Enzinger and Weiss, liposarcoma can be divided into 5 subtypes: well-differentiated, myxoid, round cell, pleomorphic and dedifferentiated. We present an unusual case of well-differentiated liposarcoma of the hypopharynx in a ...

Liposarcoma is one of the most common soft-tissue sarcomas. Calcification and ossification can occur in liposarcoma; however, the presence of both ossification and calcification is a very rare entity. We present a case of a partially calcified and ossified dedifferentiated liposarcoma of the thigh in a 76-year-old woman, which contained heterologous elements of chondrosarcoma and rhabdomyosarcoma.

This report is of a 54 year old female with omental liposarcoma. Diagnosis was made by ultrasonography, computed tomography, angiography and operation. The patient was treated by surgical excision. The histological examination revealed that the tumour was round cell liposarcoma. This is the first report to our knowledge of round cell liposarcoma of the omentum.

Primary mesenteric liposarcoma is a rare malignant tumour of mesenchymal origin. Under the MeSH classification, mesenteric liposarcoma appears to be classified with retroperitoneal neoplasms. Two synchronous mesenteric liposarcomas must be very unusual. We report a rare case of double mesenteric liposarcoma in a 66-year-old female patient. She was treated with wide surgical resection alone with...

Liposarcoma is a rare mesenchymal malignant tumor, which usually originates in the retroperitoneum and the extremities. Seven cases of primary liposarcoma of the liver have been previously reported. We present the eighth case, which occurred in an adult female patient. Primary liposarcoma of the liver, although extremely rare, must be considered in the differential diagnosis of a hepatic mass t...

Liposarcoma is the most common soft tissue sarcoma. With its various subtypes, the natural history of this disease can vary significantly from a locally recurrent tumor to a highly malignant one carrying a poor prognosis. Progress in the understanding of the specific molecular abnormalities in liposarcoma provides greater opportunity for new treatment modalities. Although surgical resection and...

Liposarcoma originating in the heart is extraordinarily rare. Herein, we report a dedifferentiated liposarcoma arising from the left atrium in a 59-year-old Chinese man. Histologically, the neoplasm predominantly consisted of undifferentiated pleomorphic sarcoma. In addition, the neoplasm exhibited lipoblastic differentiation and osteo-/chondrosarcomatous components. Immunohistochemically, the ...

Background. Liposarcoma is the second most common soft tissue sarcoma affecting predominantly the retroperitoneal space and extremities. Mesenteric liposarcoma is uncommon and occurs in the small bowel mesentery. In this paper we report the case of a recurrent mesocolon myxoid liposarcoma manifesting 6 years from the initial right hemicolectomy for the primary tumour. Case Report. A 41-year-old...
