chromophobe renal cell carcinoma

a low-grade renal cell carcinoma composed of large polygonal cells with well-defined borders and amphophilic or pale cytoplasm. These cells grow in solid sheets, but focally they may form tubules, trabeculae, or cysts.

chromophobe renal cell carcinoma

An uncommon (4–5% of all renal tumours) renal cell carcinoma with relatively indolent growth and histologic changes of renal oncocytoma. It is thought to arise in the intercalated cells of the collecting ducts.

The second commonest one was papillary carcinoma followed by chromophobe carcinoma, just as the pattern in previous studies.
There were 3 cases of clear cell carcinoma and 1 case each of papillary carcinoma and chromophobe carcinoma. Thus, 10.87% of RCC in this study group were found incidentally.

Mostly sarcomatoid carcinomas are found in association with conventional (clear cell) renal carcinoma, but there are occasional descriptions of sarcomatoid transformation of chromophobe carcinoma,[8,9] collecting duct carcinoma,[10] and papillary carcinoma.[11]

The current study had a larger proportion of chromophobe tumours as compared to other regional and international studies.162224 A larger morphological study needs to be carried out to clearly assess the prevelance of chromophobe carcinomas.In conclusion the lack of availability of advan-ced radiological techniques and the small proportion of Pakistani population which gets routine abdominal scans results in late detection of renal tumours.

The samples, selected based on pathologic diagnosis, included 62 clear cell carcinomas, 56 papillary carcinomas, 34 chromophobe carcinomas and 36 oncocytomas.

Tickoo et al[3] used the term oncocytosis because their tumors were oncocytomas, chromophobe carcinomas, or hybrid tumors.

Additional histochemical stains of periodic acid-Schiff and Hale's colloidal iron were available for chromophobe carcinomas. The total number of tumor slides for each case was recorded.
