ABSTRACT
Plasma cell granulomas (pseudotumors) are rare benign, tumor-like proliferations composed chiefly of plasma cells that manifest primarily in the lungs, but may occur in various anatomic locations. We report this case of a 54-year-old male who presented with an unusual maxillary anterior gingival overgrowth treated by excisional biopsy. Histological examination revealed a dense inflammatory cell infiltrate containing mainly plasma cells. Immunohistochemistry for kappa and lambda light chains showed a polyclonal staining pattern confirming a diagnosis of plasma cell granuloma. Intraoral plasma cell granuloma is exceedingly rare, although case reports documenting such lesions have been reported. This case highlights the need to biopsy unusual lesions to rule out potential neoplasms.

The CT scan aided diagnosis here of two odontogenic keratocysts in the maxillary sinus. The CT scan defines borders and provides insight into the contents of lesions and a three-dimensional view of an area of specific interest. In terms of diagnostic value, the CT scan has a definite advantage over other radiographic techniques. The treatment of maxillary odontogenic keratocysts was discussed, and the importance of postoperative observation was emphasized.
