Abstract

A 78-year-old woman was referred to Chonbuk National University Dental Hospital complaining of facial palsy and palpable mass on the right parotid gland area. Clinical examination showed non-specific findings of the intraoral region, but showed asymmetrical facial appearance. Panoramic view showed a large amorphous calcified mass on the posterior to the mandibular ramus and thin cortical plate of the posterior ramus. Sialogram showed constriction of the main duct and no further filling of striated, intercalated ducts and parenchymal areas. CT scans demonstrated an irregular, infiltrating mass with slight enhancement in the right parotid gland. The mass showed necrotic areas and calcifications. Bone scan showed marked accumulation of (99m)Tc-MDP on the right posterior maxilla. Microscopic findings demonstrated the minimal morphologic alterations and rare mitotic figures within tumor cells, and diagnosed as adenocarcinoma (NOS, Grade II). This report could be aid in the diagnosis of calcified lesions of the salivary gland.
