Sarcomatoid carcinoma is a high‑grade rare malignant tumor with both epithelial and mesenchymal components. Sarcomatoid carcinoma in the upper urinary tract is very rare. We reported here a case of sarcomatoid carcinoma of renal pelvis with osteosarcomatous differentiation, with involvement of the ureter and renal parenchyma in a 68-year-old female. Histologically, predominant pleomorphic spind...

Sarcomatoid transformation, wherein an epithelioid carcinomatous tumour component coexists with a sarcomatoid histology, is a predictor of poor prognosis in clear cell renal cell carcinoma. Our understanding of sarcomatoid change has been hindered by the lack of molecular examination. Thus, we sought to characterize molecularly the biphasic epithelioid and sarcomatoid components of sarcomatoid ...

Sarcomatoid squamous cell carcinomas are extremely rare, high grade, aggressive variant of penile cancers. Sarcomatoid carcinoma are biphasic neoplasms with a combination of both sarcomatoid components and carcinomatous elements. These neoplasms are very rare in the urogenital system. We report a 53-year-old male presented with an ulcerated lesion on the glans penis. The rarity of this case rei...

Sarcomatoid bladder carcinoma is a high-grade neoplasm and accounts for approximately 0,3% of all bladder malignancies. Sarcomatoid carcinoma originates from transitional cells of the bladder. Sarcomatoid carcinoma is charactericed by a epithelial component and a sarcomatoid component, consisting of spindle cells, that is only epithelial marker-positive. We report a 26-year-old woman diagnosed ...

Vulvar cancer is a rare tumor accounting for <5% of female genital tract tumors. The most common type vulvar malignancy squamous cell carcinoma. There are many histological variants carcinoma, keratinizing being the one. Sarcomatoid variant an extremely in vulva and comprises both epithelial mesenchymal features. Due to rarity this limited cases reported literature, no proper management guid...

Sarcomatoid carcinoma is a type of spindle cell neoplasm. These varieties neoplasms comprise diverse collection benign and malignant neoplasms. carcinoma, also known by various other names such as Spindle Lane’s tumor, to name few, an exceedingly rare aggressive variant squamous 3, 7, 8 The variation in its nomenclature reflects the divergent interpretation sarcomatoid component reactive or neo...

Sarcomatoid carcinoma is an extremely rare biphasic tumor characterized by a combination of malignant epithelial and mesenchymal cells. Limited data on sarcomatoid carcinoma showed that most cases occurred with advanced local disease and metastasis, and paraneoplastic syndromes were rare. We present the case of a 63-year-old man with lung sarcomatoid carcinoma associated with jejunum metastasis...

Sarcomatoid carcinomas exhibit features that are common to epithelial and mesenchymal tumors. These carcinomas are rare, particularly in the small intestine. In the current case report, we describe a case of an intestinal sarcomatoid carcinoma in a 70-year-old Chinese female. Sarcomatoid carcinoma was confirmed based on light microscopy and immunohistochemical observations. The patient presente...

BACKGROUND Sarcomatoid carcinoma is a rare, aggressive, malignant cancer composed of sarcoma and sarcoma-like components, and can occur in different organs such as the thyroid gland, bone, skin, breast, pancreas, liver, urinary tract, and lung. Pulmonary sarcomatoid carcinoma accounts for only a small percentage of lung cancers and has histological variants that include pleomorphic carcinoma, g...

The author reports a very rare and very unique urinary bladder carcinoma. This carcinoma occurred in a 68-year-old Japanese patient who underwent cystectomy for bladder tumor. The tumor was large polypoid and ulcerated one. Histologically, the tumor consisted of the following three elements: giant cell sarcomatoid carcinoma (70% in area), squamous cell carcinoma (20% in area), and papillary uro...
