Ghost Cell Odontogenic Tumor Associated with Odontoma – Report of Two Rare Cases

The ghost cell odontogenic tumor (GCOT) is a neoplastic/cystic lesion with a diverse histopathological and clinical behavior. It was formerly known as calcified odontogenic cyst, but in 2005 the World Health Organization categorized this lesion as an odontogenic, benign tumor rather than a cyst; nominating this neoplasm as calcifying cystic odontogenic tumor. A later comprehensive classification named it ghost cell odontogenic tumor, because the most remarkable histopathologic characteristic is the presence of a mass of ghost cells embedded in the epithelium. We report two cases of a rare variant of a ghost cell odontogenic tumor associated with odontoma; to our knowledge, one is the youngest patient (four month old) reported in the English literature.
