Delayed Post-Traumatic Alopecia of the Dorso-Lumbar Area Following a Road Accident in a Cat Without Pelvic Fracture

An 11-month-old female domestic short-haired cat developed non-pruritic alopecia in the dorso-lumbar area one month after a road accident, despite initially showing no dermatological lesions in that area. The cat had a fracture in the left hind limb. Four months post-accident, clinical examination revealed alopecia with histopathological findings of absent adnexae, mild fibroplasia and fibrosis, pyogranulomas at the dermo-hypodermal junction, and a moderately stenotic hypodermal artery. These findings were consistent with post-traumatic dorso-lumbar alopecia, highlighting the unique fracture location and significant histopathological changes, including pyogranulomas and stenosing arteriopathy.
