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