Sarcomatoid Carcinoma of Renal Pelvis Involving Ureter and Renal Parenchyma with Heterologous Osteosarcomatous Differentiation: A Case Report and Review of Literature

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 Carcinoma of the Penis: An Uncommon Penile Neoplasm

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 Chromophobe Renal Cell Carcinoma with Heterologous Component

Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

A giant sarcomatoid renal cell carcinoma.

A 42-year-old male patient was hospitalized for lower leg oedema, shortness of breath and body-weight loss of 5 kg over a 2-month period. Physical examination identified a pale appearance, cachexia, and a palpable abdominal mass of about 20 18 cm in the right abdomen. Ultrasound study verified the existence of a massive right-side abdominal heterogenous tumour. Due to renal failure with severe ...
