RESUMO
The knowledge of anatomical structures found in wild animals is important for the practice of medical and surgical clinic. Thus, the aim of this study was to describe the osteology and radiographic anatomy of the femur, patella, tibia, fibula, tarsal, metatarsal and phalanges of the Marshdeer Blastocerus dichotomus as a reference for clinical use and species identification. Most structures were similar to those found in domestic animals, with special features of this species. Noteworthy is, for example, the absence of the third trochanter of the femur. Although a ruminant, the Marshdeer has a fibuyla similar to the one described for the horse. B. dichotomus has four fingers on each limb, formed through three phalanges, only the third and fourth finger touch the ground, and the second and fifth finger is rudimentary. It has four proximal and two distal sesamoid bones, and sesamoid bones near the gastrocnemius muscle do not exist...
O conhecimento das estruturas anatômicas encontradas nos animais silvestres é importante para a prática da clínica médica e cirúrgica. O objetivo deste trabalho foi descrever a osteologia e anatomia radiográfica do fêmur, patela, tíbia, fíbula, tarsais, metatarsais e falanges do cervo-do-pantanal, para contribuir com o cotidiano clínico e, a identificação da espécie. A maioria das estruturas foi semelhante às encontradas nos animais domésticos, com particularidades próprias da espécie. Destaca-se, por exemplo, a ausência do terceiro trocanter do fêmur. Embora seja um ruminante, o cervo-do-pantanal apresentou a fíbula semelhante à descrita para os equinos. Este animal possui quatro dedos em cada membro, formados por três falanges, sendo que apenas o terceiro e o quarto dedos tocam o solo e, o segundo e o quinto dedos são rudimentares. Apresentou ainda quatro ossos sesamóides proximais e dois distais. Não se observou ossos sesamóides junto ao músculo gastrocnêmio...

BACKGROUND: Reports of neoplasms in Panthera species are increasing, but they are still an uncommon cause of disease and death in captive wild felids. The presence of two or more primary tumor in large felids is rarely reported, and there are no documented cases of ocular melanoma and mammary mucinous carcinoma in African lions. CASE PRESENTATION: An ocular melanoma and a mammary mucinous carcinoma are described in an African lion (Panthera leo). The first tumour was histologically characterized by the presence of epithelioid and fusiform melanocytes, while the latter was composed of mucus-producing cells with an epithelial phenotype that contained periodic acid-Schiff (PAS) and Alcian blue staining mucins. Metastases of both tumor were identified in various organs and indirect immunohistochemistry was used to characterize them. Peribiliary cysts were observed in the liver. CONCLUSIONS: This is the first description of these tumor in African lions.
