Granular Cell Ameloblastoma

Ameloblastoma is an epithelial odontogenictumour of the jaw and exhibits diverse histopathologic subtypes likefollicular, plexiform, acanthomatous and desmoplastic variantswhich occurs either singly or in combination. Granularcell ameloblastoma is a rare histological subtype of ameloblastoma accounting for less than 5% of the total. The raregranular cell variant is seen in combination usually with follicular or plexiform subtypes. The aim of this paper is todescribe clinical and microscopic features of Ameloblastoma of a pure granular cell histopathological subtype occurringin a seventeen year old adolescent female patient in the lower right region of the mandible.
