Hypertrichosis in a gibbon (Hylobates muelleri)

Key words: Hypertrichosis; gibbon; Hylobates muelleri; dermatology; pathology.

Abstract: A case of facial hypertrichosis in a museum specimen of a Bornean gibbon (Hylobates muelleri) is described. Apparently, hypertrichosis has not previously been reported to occur in non-human primates. Similar pathological conditions are known to occur in humans, but it is unknown whether any of the numerous forms of human hypertrichosis is equivalent to this case in gibbons.
