A. Right, the lesion is formed of abundant benign plasma cells forming sheets inside cellular fibroblastic stroma. Variable lymphocytes and histiocytes, were detected. Many Russel bodies and Mott cells were also seen. Kappa and Lambda staining were diffusely positive indicating polyclonality and reactive nature of the lesion. Plasma cell granuloma is also called plasma cell type of inflammatory myofibroblastic tumor. It may be a reaction to a certain stimuli or a predisposition to autoimmune disease.
B. Wrong, there was no endothelial proliferation. the lesion is formed of abundant benign plasma cells forming sheets inside cellular fibroblastic stroma.
C. Wrong, Both Kappa and Lambda staining showed diffuse positivity with no significant difference indicating polyclonality of the lesion.
