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

An 11-month-old female, neutered domestic short-haired cat developed non-pruritic alopecia in the dorso-lumbar area 1 month after a road accident, despite initially showing no dermatological lesions in that area. Four months post-accident, clinical examination revealed significant hair loss, and histopathological analysis showed absence of 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 presentation of histopathological lesions and the absence of hair follicles in the affected area.
