Definition : Verrucous hyperplasia (VH) is a rare exophytic oral mucosal lesion which can transform into verrucous carcinoma (VC), its malignant but clinically similar counterpart.
Verrucous hyperplasia is a premalignant exophytic oral mucosal lesion with a predominantly verrucous or papillary surface; this lesion can subsequently transform into verrucous carcinoma (VC), a well-established warty variant of squamous cell carcinoma (SCC).

oral plasma cell granuloma
14 November 2018Definition : An oral plasma cell granuloma (OPCG) is a rare reactive tumor such as proliferation composed chiefly of plasmacytic infiltrate. Both clinically and histopathologically, it may be misinterpreted as various pathological entities thus necessitating the complete evaluation of patient and proper histopathological and immunohistochemical analysis of the tissue.
