title: Comparative dermatology--canine endocrine dermatoses.
abstract: Endocrine diseases in the dog commonly manifest with dermatological lesions. Hypothyroidism is the most common endocrinopathy and usually presents with alopecia in areas of wear, seborrhea, and recurrent infections. Common clinical signs associated with hyperadrenocorticism include polyuria, polydipsia, and polyphagia. The most common dermatological manifestation of hyperadrenocorticism is bilaterally symmetrical alopecia sparing the head and distal extremities. Pyoderma is a common finding associated with immunosuppression. Less commonly, calcinosus cutis may occur. Sex hormone excess, primarily hyperestrogenism and hyperandrogenism, may also be associated with dermatological signs. Usually, dogs are intact, and the excess production is due to testicular or ovarian neoplasia.
