Abstract
A 6 year old
female Spitz dog was admitted to Teaching Veterinary Hospital at Chittagong
Veterinary and Animal Sciences University with the history of inappetance and
asymmetric lower jaw. Oral inspection revealed a pair of pale enlarged lobulated
mass around the third molar tooth of the left mandible. The dog was clinically
diagnosed with epulis and successfully cured by surgical excision.
Histopathological section of the excised masses revealed characteristic features
of acanthomatous ameloblastoma with some atypical lesions. Multifocal areas of
ameloblastic islands were found in the dense sheet of proliferating epithelial
layer protruding towards the sub epithelial connective tissue stroma. These
islands were characterized with irregular epithelial stratification at the basal
layer. Besides, presence of ghost cells was the unusual findings for such case.
Prominent intercellular bridging and nuclear polymorphism in odontogenic cells
were other decisive characters of the lesion. Based on the histomorphological
appearance, the gingival tumor was designated as canine acanthomatous
ameloblastoma (CAA) with atypical histomorphology.
