FIBRO EPITHELIAL POLYPOF ORAL CAVITY IN MASSON TRI CHROME STAIN Fibroepithelial polyp is characterized by a pink, red or white knob-like growth. This is caused by minor trauma or irritation, usually following accidental biting. They are small and generally painless. They are usually single, but occasionally multiple.Masson’s trichrome stain is the three color staining used in histology.Masson’s trichrome stains were performed on the tissue sections of the reactive lesions of oral cavity .All the reactive lesions show different growth and differentiation.masson’s trichrome stains is used in fibro epithelial polyp to find out the fibrous nature of the lesions. In this study we are going to use masson’s trichrome stain to find the the importance of the histopathological diagnosis of fibroepithelial polyp lesion having rare, unusual and abiding features but which is one of the most common lesions of the oral cavity.
