he·mo·sid·er·in

(hē'mō-sid'ĕr-in),
A golden yellow or yellow-brown insoluble protein produced by phagocytic digestion of hematin; found in most tissues, especially in the liver, spleen, and bone marrow, in the form of granules much larger than ferritin molecules (of which they are believed to be aggregates), but with a higher content, as much as 37%, of iron; stains blue with Perls Prussian blue stain.

A correct diagnosis of ChRCC may be possible on cytomorphology along with a Hale's colloidal iron stain and confirmed by immunohistochemical and FISH analysis in difficult cases.
A colloidal iron stain highlighted increased interstitial mucin.
Histologic analysis revealed vascular ectasia and superficial interstitial and perifollicular and perineurovascular granulomatous reaction with increased mucin (colloidal iron stain examined), with occasional lymphocytes and eosinophils, consistent with postherpetic granuloma or an interstitial granuloma annulare-like tissue reaction.
Chromophobe renal cell carcinoma is diffusely positive for Hale colloidal iron stain and usually expresses E-cadherin or kidney-specific cadherin, pancytokeratin (AE1/ AE3), and CK7, but is negative for vimentin, c-kit, and SMA.
Iron stains are most often created by ungalvanized nails, wire brushes and steel wool.
A semiquantitative method for assessing iron stains was adapted from Scheuer et al[21] as follows: 1+, staining present in less than 25% of hepatocytes; 2+, staining present in 25% to 75% of the hepatocytes; 3+, staining present in more than 75% of hepatocytes; and 4+, heavy staining present in almost all hepatocytes and also in the biliary duct epithelium.
