Resumen
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 2–7y (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.
