Abstract
Adult onset progressive alopecia and leukotrichia developed in 2 registered black Angus cows, aged 6 and 7 years. Histopathologic findings in skin were prominent melanin clumping and degeneration of matrix cells with formation of giant multinucleate cells within hair bulbs, accompanied by peribulbar melanin incontinence and fibrosis and dystrophic hair shafts. Intrabulbar and peribulbar lymphocytes were cluster of differentiation (CD)3-positive T cells. Findings were characteristic of alopecia areata.
