Pathologists call this condition '''''apocrine''' metaplasia'', meaning a transformation of the normal epithelial cells into sweat-gland-like cells similar to those found in the ' apocrine glands of the vulva, eyelid, and external auditory canal. Il se compose de diverses structures comme les glandes sudoripares, les follicules pileux, les vaisseaux sanguins, les terminaisons nerveuses et les trois couches: l'épiderme, le derme et l'hypoderme.

Description– Apocrine glands are the major type of sweat glands in dogs. Although the presence of the classic apocrine feature, picturesquely described as epithelial snouts or decapitation secretion, or other manifestation of apocrine differentiation, such as the presence of plasmacytoid epithelial cells or mucin, allows the pathologist to designate a glandular or ductal proliferation as apocrine, the lack of such features does not exclude an apocrine derivation. Br Vet J … Perineal and perianal involvement is more common in men, as well as more unusual sites of involvement (eg, retroauricular region and chest).
