Perosomus Elumbis (PE) is a rare congenital disorder characterized by absence of caudal spine (lumbar, sacral, and coccygeal vertebrae). Here, we present the first reported case of PE in a rhesus macaque (Macaca mulatta) and relate our findings to those described in other species.
Keywords: Perosomus Elumbis; congenital; non-human primate; stillborn.
