Background: tumor disease is a deadly in the world. It estimated that around 1,300 people die each year from bone tumors. Bone tumors occur due to abnormal growth of mesenchymal cells bones, which can be malignant/cancerous. Malignant soft tissue affect anyone, especially elderly. In developing malignancy, it necessary have nutritional service assistance support adequacy sufferers.Purpose: dete...

Background: Gastrointestinal stromal tumors (GISTs) constitute the majority of gastrointestinal mesenchymal tumors. They usually express a proto-oncogen protein called CD117 detected by immunohistochemistry. This study investigated the differentiation of GISTs as well as the risk of aggressive behaviors in GISTs from surgically-treated patients in university affiliated hospitals. Methods: The c...

Background:   Although the majority of soft tissue masses are benign, it is important to consider malignancy in differential diagnoses. Because most soft tissue sarcomas present as a painless mass, clinicians must watch for signs suggestive of malignancy, including large size, rapid growth, and site deep into the deep fascia.The purpose of this study was to determine the relative prevalence acc...

Phyllodes tumors of the breast are rare neoplasms that account for <1% of all mammary tumors and 2-3% of fibro-epithelial neoplasms of the breast. We evaluated the clinicopathological characteristics of a cohort of 246 Chinese patients in relation to the expression of epithelial-to-mesenchymal (EMT) markers in benign, borderline and malignant tumors and the prognostic value of different surgica...

Tumors of the reproductive system in bitches can affect any its anatomical structures. The predominant lesions are those appearing vagina and vulva, accounting for about 2.4-3% all tumors bitches, followed by ovarian – 0.5-1.2%, while uterine rare it is difficult to even estimate their incidence. most common type tumor granulosa cell (GCT), which originates from cells Graff follicle. In uterus,...

purpose : choroidal melanoma is the most common primary ocular malignancy among the adult population. authors investigated the clinical findings, histopathologic features, types of retinal detachment and the precise anatomic origin of enucleated eyes for primary ocular malignant melanoma in shiraz university of medical sciences (sums) hospitals between 1990 and 2005. methods : this was a cross ...

Tumors of peripheral nerve are largely neuroectodermal in nature and derived from 2 elements of nerve, Schwann or perineurial cells. In contrast, mesenchymal tumors affecting peripheral nerve are rare and are derived mainly from epineurial connective tissue. The spectrum of the latter is broad and includes lipoma, vascular neoplasms, hematopoietic tumors, and even meningioma. Of malignant perip...

GREM1 is a secreted protein that antagonizes bone morphogenetic proteins (BMPs) and participates in critical biological processes, including embryonic development, organogenesis tissue differentiation. Gremlin 1 (GREM1) also an inhibitor of TGF‑β ligand for vascular endothelial growth factor receptor 2. In addition, can induce cells, participate the process epithelial‑mesenchymal transition, th...

Perivascular epithelioid cell neoplasms (PEComa) are rare mesenchymal tumors that can occur in any part of the body and have unpredictable pathological behavior. They are usually benign, but may be malignant. We present a case of malignant PEComa of the pelvic retroperitoneum treated with radical surgery.

In total, 95% of primary tumors in the pancreas are epithelial tumors; primary mesenchymal tumors at this site are extremely rare. At present, only one comprehensive study about these rare tumors has been performed. Another retrospective analysis of these rare tumors is performed in the present study, which, to the best of our knowledge, is the first to be performed in China. In the present stu...
