Downloa pose: Myxoid liposarcoma is a common subtype of liposarcoma. It is associated in more than 90% es with the chromosomal translocation t(12;16)(q13;p11) leading to the fusion FUS-CHOP gene responsible for the oncogenic transformation of preadipocytes. Recently the marine natural prodbectedin has shown highly selective activity for myxoid liposarcoma, even in the most aggressive -cell subt...
For prognostic analyses of p53 alterations (p53 gene mutations + p53 immunopositivity) and Mib-1 proliferation index, we investigated 42 primary malignant lipomatous tumors for which complete clinical data and a long follow-up were available. p53 gene mutations were investigated by PCR-single strand conformation polymorphism-sequencing analysis, and immunohistochemistry was used to determine p5...
ZC3H7B-BCOR high-grade endometrial stromal sarcomas: a report of 17 cases of a newly defined entity.
High-grade endometrial stromal sarcoma likely encompasses underrecognized tumors harboring genetic abnormalities besides YWHAE-NUTM2 fusion. Triggered by three initial endometrial stromal sarcomas with ZC3H7B-BCOR fusion characterized by high-grade morphology and aggressive clinical behavior, we herein investigate the clinicopathologic features of this genetic subset by expanding the analysis t...
Differential diagnosis of myoxid lesions in head and neck area with special staining of mucin Dr. M. Eslami* - Dr. M. Ashoori** *- Associate Professor of Oral pathology Dept. - Faculty of Dentistry - Tehran University of Medical Sciences. ** - Assistant Professor of Oral pathology Dept. - Faculty of Dentistry - Kerman University of Medical Sciences. Background and aim: Myxoid histological pa...
Liposarcoma is a common malignant soft tissue tumor, accounting for 10% to 16% of all sarcomas. Multicentric myxoid liposarcoma is an uncommon condition. Differentiation between several primary tumors and metastasis of a single liposarcoma represents the main difficulty in diagnosis. A 47-years old woman presented with right thigh myxoid liposarcoma and underwent wide margin tumor resection. Ot...
Myxoid and round cell liposarcoma is a variant of liposarcoma characterized by a morphologic continuum in which tumor progression from low-grade myxoid to high-grade hypercellular or round cell areas may be observed. A 28-year old man presented with a painful skin colored subcutaneous mass on his left flank. The skin lesion was discovered about two months ago. Computed tomography revealed a wel...

Note Sarcomas are relatively rare malignant tumours and comprise less than 10% of all cancers. Classical classifications of sarcomas are based on the site of tumour (bone or soft tissue). Soft tissue sarcoma (STS) is the collective term used for malignancies arising in muscles, fat, vessels, the peripheral nervous system and fibrous tissue. Histopathologic examination of such tumours has reveal...
Macroscopic findings: the tumour presents as lobulated or multinodular mass, generally well circumscribed by a distinct fibrous capsule.The size of the tumour at the time of diagnosis may vary from 1 to about 20 cm (mean size: about 7 cm). Histology: typically, tumour nodules are composed of round or slightly elongated cells, with minimal features of chondroblasts, separated by mucoid substance...
Primary liposarcomas of the mediastinum are extremely rare neoplasms, comprising less than 1% of all mediastinal tumors. These tumors occur most commonly in the lower extremities (75%) and less frequently in the retroperitoneum. We present a case involving a successful radical resection of a large myxoid liposarcoma and its recurrence, both located in the posterior mediastinum.
