Sebaceous adenitis in four domestic rabbits (Oryctatagus cuniculus)

Four domestic rabbits were presented with a history of nonpruritic scale. Multiple skin biopsies revealed findings compatible with sebaceous adenitis as reported in other species: inflammation directed at the sebaceous gland, and/or an absence of sebaceous glands, a perifollicular lymphocytic infiltrate at the level of the absent sebaceous glands, hyperkeratosis, follicular keratosis, follicular dystrophy, perifollicular fibrosis, and a mural infiltrative lymphocytic folliculitis. Histological changes not consistent with sebaceous adenitis in other species were interface dermatitis and interface folliculitis with single cell necrosis and basal cell hydropic degeneration.
