Sebaceous adenitis with hyperkeratosis in the Standard Poodle: a discussion of 10 cases

Ten Standard Poodles were evaluated for progressive symmetrical scaling and alopecic dermatosis. The skin disease occurred in young adult Standard Poodles, either black or apricot, and was characterized by progressive symmetrical non-pruritic scaling with associated partial alopecia which began on the dorsal midline and ears and occasionally involved the ventral abdomen and chest. Histologically there was prominent hyperkeratosis and a nodular granulomatous-to-pyogranulomatous inflammatory reaction at the level of the sebaceous glands, with subsequent sebaceous gland destruction. The proposed name for this condition is sebaceous adenitis with hyperkeratosis. Currently, treatment is symptomatic and similar to the treatment of the idiopathic seborrhoeic disorders..
