RESUMO
African pygmy hedgehogs (Atelerix albiventris) frequently develop oral neoplasms, and most of these neoplasms are malignant. We characterized oral masses detected in hedgehogs at clinical examination. During a 1-y period, we diagnosed oral cavity masses in 27 privately owned hedgehogs; 16 were female and 11 were male, with ages of 2-7 y (mean: 4.3 y). Eight masses were non-neoplastic and were diagnosed as gingival hyperplasia (GH). Nineteen masses were neoplastic, of which 17 were squamous cell carcinomas (SCCs) and 2 were mesenchymal tumors (1 spindle cell tumor of probable neural origin, and 1 hemangiosarcoma). The GHs were noninvasive, exophytic, and did not recur after surgical excision. The SCCs were highly invasive tumors that induced facial deformation and were located in the caudal portion of the oral cavity, with 12 of them arising from the right-caudal maxilla. Thus, clinical signs, growth pattern, and anatomic location can be used to suspect a diagnosis of SCC among the other possible diagnoses, such as GH, in this location. However, histopathology is necessary for confirmation. Also, hemangiosarcoma should be considered among the differential diagnoses.

La cavidad bucal está conformada por diversas estructuras anatómicas, donde las glándulas salivales desempeñan funciones de vital importancia como son la producción y excreción de saliva. Las mismas se dividen en glándulas salivales mayores y menores. Las glándulas salivales mayores son las glándulas parótidas, las submaxilares y las sublinguales. Las glándulas salivales menores están distribuidas en diferentes localizaciones anatómicas de la mucosa bucal. Ellas son: las glándulas labiales, palatinas, genianas y linguales. Éstas últimas a su vez están conformadas por las glándulas de Blandin y Nühn, Weber y Von Ebner. El objetivo de este trabajo es destacar la importancia de estas glándulas en cuanto a su ubicación anatómica, inervación é irrigación
The oral cavity is formed by different anatomic structures; in wich the salivary glands have important vital functions such as production and excretion of saliva. These glands are divided in two groups: mayor salivary glands and minor salivary glands. The mayor salivary glands are the parotid, submaxilar and sublingual glands. The minor salivary glands are distributed in different anatomic locations in the oral cavity. These glands are: the labial glands, the palatine glands, the genians glands and the lingual glands. These lingual glands are also formed by the Blandin and Nuhn glands, the Weber glands and the Von Ebner glands. The objective of this work is to determine the importance of these glands in matter of their anatomic location, inervation and irrigation
