Suspected congenital hypothyroidism tied to alopecia in wombat

A suspected case of congenital hypothyroidism in an 18-month-old southern hairy-nosed wombat with progressive generalized alopecia is adding a rare endocrine diagnosis to the differential list for exotic and wildlife clinicians. According to the case summary in Veterinary Dermatology, the wombat had decreased thyroid hormone levels, and its coat improved after thyroxine treatment, leading the authors to describe suspected congenital hypothyroidism as the likely cause of the noninflammatory alopecia. The report appears to be a single-animal case from Amelia S.Y. Ho and Meng K. Siak, and it centers on the species Lasiorhinus latifrons, the southern hairy-nosed wombat. (pubmed.ncbi.nlm.nih.gov)

Why it matters: For veterinary professionals, the case is a reminder that alopecia in wombats shouldn’t automatically be treated as parasitic, infectious, or husbandry-related. Sarcoptic mange is a well-known cause of alopecia and dermatitis in wombats, and prior field research in southern hairy-nosed wombats has also linked poor coat quality and alopecia with broader health and environmental pressures, so an endocrine workup may be easy to overlook. This case suggests congenital endocrinopathies deserve consideration when a young wombat presents with generalized, noninflammatory hair loss, especially if the pattern or response to initial treatment doesn’t fit more common causes.

What to watch: Whether the full case report prompts more published reference data for thyroid testing in wombats, or additional case recognition in zoo, wildlife, and exotic practice. (pubmed.ncbi.nlm.nih.gov)
