Abstract:BACKGROUND: Fine needle aspiration cytology (FNAC) of jaw tumors has not been studied extensively. Ameloblastomas are jaw tumors that show a wide morphologic spectrum and thus may pose some diagnostic difficulties. Of the many types, granular cell ameloblastoma (GCA) is an uncommon variant that possesses distinctive features. To the best of our knowledge, there have been no previous reports on the cytologic findings of GCA. We present two cases diagnosed by FNAC. CASES: Two cases of GCA were diagnosed on cytology and subsequently confirmed on histology. Both patients presented with a large, lytic jaw tumor. FNAC smears showed characteristic granular cells along with spindle and basaloid cells. CONCLUSION: Although GCAs are rare tumors, they possess distinctive features that permit an accurate diagnosis, provided that this entity is kept in mind. This tumor has to be differentiated from cystic odontogenic lesions, epulis and granular cell myoblastoma. An accurate preoperative diagnosis also helps the surgeon to plan more extensive surgery as these tumors show a great propensity for malignant change and metastases.
