Oral Mucosal Calcified Nodule: Report of a Case and Review of the Literature.

Abstract

The oral mucosal calcified nodule (OMCN) is a rare soft tissue lesion with only 7 cases reported in the English literature. It typically presents in the pediatric population as an asymptomatic submucosal nodule of less than 2 cm size affecting the maxillary ridge or palate, though other sites are reported. The histopathology displays stratified squamous epithelium overlying fibrous connective tissue with embedded calcified aggregates bordered by variable numbers of multinucleated giant cells. Surgical excision is curative. In this report, we present a new case of OMCN, outline the characteristic histopathologic features and review the cases reported in the English literature.
