Renal cell carcinoma is the most common type of renal malignancy and it originates from the renal tubular epithelium. Due to the diversity in the histopathological and molecular characteristics, it is typically subclassified into five different categories. Papillary renal cell carcinoma is one subclassification and it includes two variants: sporadic and hereditary. Although the hereditary form ...

We report a case of contralateral renal displacement due to a giant ipsilateral renal cyst. Drainage and partial excision of the cyst was followed by return of the kidney and liver to their normal positions. Incidentally, a small focus of renal cell carcinoma was found after pathologic examination of the cyst wall. The relevant literature is reviewed.

Sarcomatoid change in renal cell carcinoma is the result of the dedifferentiation of the "parent" tumor into a high-grade malignancy characterized by sarcoma-like features and associated with an accelerated clinical course and poorer prognosis. Any of the renal cell carcinoma subtypes can undergo sarcomatoid dedifferentiation, with the chromophobe variant being the most prone. The present repor...

Approximately 15% of renal cell carcinomas metastasize to the head and neck region. Here in, we report a rare case patient who underwent nephrectomy for carcinoma (RCC) ten years ago presented with metastatic on her lower lip. A 65-year-old woman rapidly growing mass Pathology resulted in metastasis. Although is uncommon, metastasis should be considered differential diagnosis vascular lesion ar...
