Clinicopathological and immunohistochemical analysis of plasma cell gingivitis- A retrospective study.

Background: This study aims to describe the demographics and clinicopathological characteristics of the cases of plasma cell gingivitis (PCG) reported in our institute, supported by a review of pertinent literature. Further, we investigated the role of the cluster of differentiation CD138, Ki67, CD56, and CD117 immunoexpression in the differential diagnosis of PCG from plasma cell dyscrasias.

Materials And Methods: All histopathologically confirmed cases of PCG, whose relevant details could be obtained, were included in this study.

Distribution of biopsied gingival lesions according to the proceedings from the 2017 World Workshop classification: A three-year retrospective study.

Background: The gingiva is a common site for neoplastic or non-neoplastic lesions. Neoplasms refer to progressive autonomous growth that can have either a benign or a malignant course. On the other hand, non-neoplastic lesions are mainly inflammatory, or occur as a reaction to some kind of irritation or lowgrade injury.

Role of MDM2, CDK4, BCL2, Parafibromin and Galectin 1 in Differentiating Osteosarcoma from its Benign Fibro-osseous Lesions.

Benign fibro-osseous lesions (BFOLs) are a diverse group of lesions showing considerable degree of overlap with low grade osteosarcoma (LGOS). Further, de-differentiated osteosarcoma (DOS) is usually indistinguishable from conventional high-grade OS (COS) if LGOS foci are not identified. Thus, there is a need for adjunctive immunohistochemical markers to differentiate OS from benign FOLs as well as DOS from COS.
