Ichthyosis (fish scale disease) is a rare hereditary disease and characterized by excessive cutaneous scale formation. A male HanWoo calf born by natural service was found with fissures and thickened, scaly, cutaneous plates covering over 90% of its body. Histopathological feature was excess compact orthokeratotic hyperkeratosis involving surface of the epidermis and follicular epithelia. The calf had small malformed ears, ectropion, eclabium and an abnormal nose. Gross and histopathologic findings in calf were consistent with those of harlequin ichthyosis, and it was the first observed harlequin ichthyosis in HanWoo cattle.
