Wombat case report links alopecia to suspected hypothyroidism

A new case report in Veterinary Dermatology describes an 18-month-old southern hairy-nosed wombat with progressive generalized alopecia that was ultimately suspected to have congenital hypothyroidism. The authors, Amelia S.Y. Ho and Meng K. Siak, reported decreased thyroid hormone concentrations compared with age-matched controls, histopathology showing atrophic hair follicles in telogen, and clinical improvement after thyroxine treatment. The report appears to be one of the few published descriptions linking a congenital endocrinopathy to noninflammatory alopecia in a wombat, broadening the differential list for hair loss in this species.

Why it matters: For veterinary professionals working in zoological, wildlife, or exotic animal practice, the case is a reminder that not all alopecia in wombats should be attributed to parasitic, infectious, or environmental causes. Sarcoptic mange is a well-known cause of hair loss in wombats, and toxic or systemic disease has also been reported in southern hairy-nosed wombats, so endocrine disease may be easy to overlook without hormone testing and skin histopathology. More broadly, veterinary guidance in other species recognizes congenital hypothyroidism as a cause of poor coat quality and alopecia, which makes this report clinically useful even as a single-case observation in an uncommon patient.

What to watch: Watch for whether this case prompts additional reporting on thyroid reference intervals, diagnostic workups, and treatment protocols for alopecic wombats in managed care. (eurekamag.com)
