Focally extensive alopecia affecting the distal limbs is a common clinical finding in rhesus macaque (Macaca mulatta) colonies and is both a regulatory and colony-health concern. We performed diagnostic examinations including physical exams, bloodwork, skin scrapes, surface cytology, and surface bacterial-fungal cultures on 17 rhesus macaques with this presentation of alopecia. Skin biopsies from alopecic skin obtained from each macaque were compared with those of normal skin from the same animal.
