Odontogenic ghost cell tumor is a rare, neoplastic form of calcifying odontogenic cyst (Gorlin cyst) whose cytologic features have not been previously reported. We present a case of odontogenic ghost cell tumor diagnosed by fine‐needle aspiration biopsy (FNAB). The aspirate was characterized by (1) tissue fragments with basaloid epithelial cells, (2) “ghost” cells, (3) scattered multinucleated giant cells, (4) rare, eosinophilic, densely hyalinized “dentinoid” material in close association with the basaloid cells, and (5) calcific debris. The aspirate was diagnosed as “consistent with odontogenic ghost cell tumor.” The cytologic features of odontogenic ghost cell tumor, as described, closely parallel the major histologic findings in this rare tumor. The differential diagnoses include other odontogenic tumors, squamous cell carcinoma, basaloid cell tumors of the salivary gland, and pilomatrixoma. Diagn.
