| Abstract: | The Grey Mouse Lemur (Microcebus murinus) is a nocturnal lemur species that lives only in Madagascar. It is one of the most abundant lemur species and its native populations are not endangered, but animals belonging to this species are rarely exhibited in zoos. While tumours are quite frequently described in other primates, there are very few publications about neoplasia in lemurs. In this case report we describe a mandibular osteoblastic osteosarcoma in a Grey Mouse Lemur (Microcebus murinus). To the best of the authors' knowledge, this is the first scientific article describing osteosarcoma in a prosimian and also reporting a tumour in the mandible in this taxon. |
