apocrine cystic calcinosis
see calcinosis circumscripta.
apocrine cystic dilatation
a relatively common finding in dog skin; may be associated with hyperplasia of glandular epithelium or secondary to duct obstruction.
apocrine cystomatosis
see apocrine gland cyst (below).
apocrine gland cyst
cystic hyperplasia of apocrine sweat glands; common in dogs. Often multiple and called apocrine cystomatosis.
apocrine sweat gland
the most abundant type of sweat gland in domestic animals and part of the hair follicle complex; found in haired skin and specialized regions such as the anal sacs. Under sympathetic nervous control and produce sweat by a merocrine mechanism (despite the name) which, in normal quantities, contributes to a protective film on the skin. Specialized apocrine sweat glands are located in the external ear canal and eyelids. Inflammation is called hidradenitis.
apocrine tumors
cystic or papillary adenomas and papillary or tubular carcinomas occur, particularly in dogs and cats. See also anal sacs tumor.
