Abstract

Acanthomatous epulis is a malignant form of gingival tumor. This is a case of epulis affecting a four-year old, intact, female Maltese dog raised as indoor pet in Iksan city. Clinical examination showed an enlarged palpable mass along the rostral maxillary gingiva. Section of the excised mass showed epithelial overgrowth and expansion from the basal portions through the tissue stroma. Post-surgical radio-graph showed displacement of the first and second maxillary incisors. Histochemical staining showed strongly positive reaction to epithelial marker cytokeratin and moderately positive reaction to connective tissue marker vimentin. This case was diagnosed as a form of maxillary gingival acanthomatous epulis. Routine clinical oral examination is suggested.
