Sebaceous adenitis is an uncommon skin disease in the dog and rare in cats, rabbits, horses, and humans. The disease was first described in 3 dogs by Scott in 1986. It is an inflammatory disease focusing on the sebaceous glands, eventually leading to their destruction.
Affected dogs are generally young to middle-aged adults. No definitive sex predilection has been documented, although a male predisposition has been suggested in some studies.
Clinical signs include varying degrees of alopecia, hyperkeratosis, and seborrhea, with follicular casts as a distinctive feature of this inflammatory skin disease. When a hair follicle is surrounded by a sheath of keratinaceous debris, this is known as a follicular cast. The cast remains attached to the hair shaft as the hair grows. Pruritus can be variable but is worsened by secondary infection. Early lesions can include both scaling and erythema.
