Central granular cell odontogenic tumor of mandible in a child.

Central granular cell odontogenic tumor (CGCOT) is sporadic benign odontogenic tumor and it especially occurs in women older than 50 years of age. Radiologically it manifests as unilocular to the multilocular radiolucency with sometimes mixed densities. Histopathology displays sheets and islands of large eosinophilic cells with abundant granular cytoplasm, however few cases exhibit inadequate epithelium, thus creating a diagnostic confusion. Though, resection is advocated by some surgeons, however because of the non-aggressive biological behaviour, enucleation or curettage is the treatment of choice for this lesion. Till now only 39 cases have been reported in the past six decades. We are reporting the first case of CGCOT occurring in the youngest age of eleven-year-old patient with massive size of 11 × 7 × 6 cm. This would add CGCOT as a differential diagnosis in the bony lesions of younger individuals. In addition, the importance of immunohistochemistry studies in cases with scarce odontogenic epithelium and the potential role of Carnoy's solution in the management of this rare tumor in this age group was emphasized.
