Exophytic gingival growth of the maxillary canine region in a young individual: Extremely rare case report of peripheral dentinogenic ghost cell tumor

The present case report is a case of peripheral dentinogenic ghost cell tumor (PDGCT), an extremely rare solid benign neoplastic variant of calcifying cystic odontogenic tumor of the gingiva mimicking clinically as pyogenic granuloma, fibroma, peripheral ossifying fibroma, and peripheral giant-cell granuloma. A 24-year-old male reported with painless, firm, solitary, sessile, smooth-surfaced, nonulcerative, nonpulsatile, well-defined swelling measuring approximate to 12 mm x 9 mm in the interdental gingiva of the teeth #13 and #14 extending to the mucogingival junction. Intraoral periapical radiographic showed a normal trabecular pattern with mild radiolucency without bony expansion, periapical lesion, and resorption of the adjacent teeth. The diagnosis was established by histopathologic examination. Very few cases of this entity have been documented in the literature. The present case report aims to document this rare entity and emphasizes on the fact that histopathological examination of every localized gingival growth should be included in the treatment planning to differentiate with other commonly found lesions.
