figure 10) The resected specimen of the mass was subjected to thorough histopathological examination by special stains like periodic acid-Schiff (PAS), silver impregnation for reticulin, Bodian's stain for nerve fibres and toluidine blue to rule out other differential diagnoses & to reach to a final conclusion.
Eight micrometer sections were made using a Reichert-Jung Leica model 2040 Autocut, and the following techniques were used: Toluidine Blue (routine), Periodic Acid of Schiff (PAS, carbohydrates), Bromophenol Blue (proteins) (Pearse, 1985) and Nile Blue (lipids) (Hawes and Satiat-Jeunemaitre, 2001).
The sections were stained with toluidine blue/basic fuchsin stain (1% toluidine blue O [C.
