Synovial sarcoma (SS) in young adult mainly involves periarticular region of the extremities. Synovial sarcomas are exceedingly rare neoplasms of the digestive tract. In this report, we describe a very rare occurrence of primary SS of the esophagus in a 30-year-old female. Patient presented with dysphagia. Endoscopy showed submucosal esophageal polyp. Piecemeal polypectomy was done. Histologically, the tumor demonstrated biphasic morphology with epithelial and mesnchymal component. Tumor cells expressed pancytokeratin, bcl-2 and CD99 antigens.

Abstract First characterized by Stroebe, the gliosarcomas are highly malignant and rare primary tumor of the brain composed of neoplastic glial cells in association with spindle cell sarcomatous elements (biphasic tissue patterns). In spite of being recognized as two different pathologies studies have not shown any significant differences between gliosarcoma and glioblastoma with regard to age, sex, size, clinical presentation, and median survival. In summary, gliosarcoma is an aggressive tumor with a propensity to recur and re-grow with poor outcome. Future studies are needed to understand th

Renal cell carcinoma (RCC) represents a heterogeneous disease, encompassing an increasing number of tumor subtypes. Post-2016, the World Health Organization (WHO) classification recognized that the spectrum of papillary renal cell carcinoma is evolving and has long surpassed the dichotomic simplistic “type 1 versus type 2” classification. The differential diagnosis of pRCC includes several new provisional/emerging entities with papillary growth. Type 2 tumors have been cleared out of several confounding entities, now regarded as independent tumors with specific clinical and molecular backgroun

Synovial sarcomas are rare soft tissue tumors which histopathologically can be divided into monophasic, biphasic and mixed variants. As part of a protocol for intra-arterial chemotherapy 12 patients with biopsy proven synovial sarcoma underwent angiography. The angiograms on these patients were reviewed to determine whether synovial sarcomas and their variants demonstrated a characteristic angiographic appearance. Synovial sarcomas appeared angiographically as soft tissue masses which showed a fine network of tumor vessels with an inhomogeneous capillary blush. Their degree of vascularity vari

Abstract Pleural mesothelioma (PM) comprises three major histologic types: epithelioid, sarcomatoid, and a mixture of the two types termed biphasic. We and others have investigated whole transcriptome profiles of bulk PM samples, identifying a molecular gradient with features of epithelial-mesenchymal transition, which is related to, but not redundant with, histology. To date bulk studies of heterogeneity across PM tumors have not explained how biphasic tumors contain sarcomatoid (mesenchymal) and epithelioid (epithelial) components.

Integrins participate in the pathogenesis and progression of tumors at many stages during the metastatic cascade. However, current evidence for the role of integrins in breast cancer progression is contradictory and seems to be dependent on tumor stage, differentiation status, and microenvironmental influences. While some studies suggest that loss of α2β1 enhances cancer metastasis, other studies suggest that this integrin is pro-tumorigenic. However, few studies have looked at α2β1 in the context of bone metastasis. In this study, we aimed to understand the role of α2β1 integrin in breast can

Cancer is an extremely complex disease, both in terms of its causes and consequences to the body. Cancer cells acquire the ability to proliferate without control, invade the surrounding tissues and eventually form metastases. It is becoming increasingly clear that a description of tumors that is uniquely based on molecular biology is not enough to understand thoroughly this illness. Quantitative sciences, such as physics, mathematics and engineering, can provide a valuable contribution to this field, suggesting new ways to examine the growth of the tumor and to investigate its interaction with

The PT is a rare fibroepithelial tumor that is histologically divided into three grades: benign, malignant, or borderline. Although only about 10% of these tumors are malignant, even benign tumors are prone to local recurrence and can become very large in size.

Introduction: Initially described in the literature by Hamperl in 1970, breast adenomyoepithelioma (AME) is a rare tumor that can mimic other epithelial, myoepithelial, or biphasic lesions of the breast. It is characterized by a dual proliferation of myoepithelial and luminal cells, with variable biological behavior, most of which are benign. In the classification published by the World Health Organization in 2019, AME was defined as an epithelial-myoepithelial lesion of the breast.

As a great deal of tissue function and structure is related to the control and transport of fluids and fluid-borne agents, there is clearly a need for this insight in all tissues.
