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.
Plasma cell granuloma (PCG) is a rare, nonneoplastic lesion consisting of a proliferation of inflammatory cells (...) -

Intraoperative Margin Assessment
The surgical method of margin sampling affects local control, pathologists’ approach to margin sampling, and clarity of pathology reports.
Studies have shown that exclusive reliance on tumor bed margins is associated with worse local control and should be avoided.
En bloc resections and margins obtained from the resection specimen remain the “gold standard.”
Successful surgical treatment of early carcinomas of the oral cavity relies on close (...)
