Abstract

Epulis refers to any tumor or similar growth on the gingival tissue and is considered the most frequent of benign oral masses in dogs. Epulis is classified into four types based on histological characteristics: fibromatous, ossifying, acanthomatous and giant cell. The aim of the present study was to present knowledge on benign oral tumors and epulides as well as report a clinical case of ossifying epulis in a male dog (Labrador) aged 25 months. The integrated treatment plan initiated with a diagnostic investigations through hematological, biochemical and serological exams for the study of antibodies for ehrlichiosis, anaplasmosis, dirofilariasis and Lyme disease as well as electrocardiogram and intraoral and thoracic x-rays, followed by the removal of the suspected tumor mass through excisional biopsy. The sample was sent for histopathological analysis for the definitive diagnosis, which confirmed ossifying epulis. In conclusion, surgery was the treatment of choice and only a histopathological analysis can confirm the type of oral neoplasm and prognosis.

Highlights

The oral cavity is a complex structure formed by different types of tissues, each of which can give rise to a variety of growth classified as either benign or malignant depending on the biochemical, morphological and functional characteristics (De Nardi et al, 2002) as well as the origin of the embryonic tissues (Verstraete, 2005)
Neoplasms are common in canines and oral tumors account for 6% of all neoplasms in this species 4, making the oral cavity the fourth most frequent site for such tumors (White, 2003)
The oral cavity of dogs is formed by different types of tissue that can give rise to a variety of malignant or benign neoplasms, which account for 6% of all neoplasms in this species (Gomes et al, 2009)

Summary

Introduction

The oral cavity is a complex structure formed by different types of tissues, each of which can give rise to a variety of growth classified as either benign or malignant depending on the biochemical, morphological and functional characteristics (De Nardi et al, 2002) as well as the origin of the embryonic tissues (Verstraete, 2005). Among oral masses in dogs, epulis is the most commonly encountered benign tumor in veterinary dentistry This is a growth that presents as firm, solid, with a peduncled appearance growing around the gingival tissue (Oakes et al, 1993), originating from the stroma of the periodontal ligament (White, 2003) and histologically classified as acanthomatous, ossifying or fibromatous, the latter of which is the most frequent form and generally not very invasive. Acanthomatous epulis is the most invasive form of the three and often demonstrates areas of osteolysis during a radiographic examination, but does not metastasize Due to this aggressive characteristic, bone resection is sometimes necessary to achieve satisfactory treatment results (Oakes et al, 1993)
