SUPPURATIVE INFLAMMATION OF APOCRINE SWEAT GLANDS (SUPPURATIVE HIDRADENITIS) IN THE DOG - A RETROSPECTIVE CLINICOPATHOLOGICAL ANALYSIS OF 100 CASES

A retrospective clinicopathological study was conducted on 100 dogs wi th suppurative hidradenitis as determined by skin biopsy. No apparent age, breed, or sex predilections were recognized. All dogs had been gi ven a clinical diagnosis of bacterial folliculitis, furunculosis, or b oth of these, whether primary or secondary to other dermatoses. There were no clinical lesions that uniquely suggested the presence of suppu rative hidradenitis. In 73 dogs, suppurative hidradenitis occurred in conjunction with varying degrees of hair follicle inflammation microsc opically. In 27 dogs, suppurative hidradenitis was the only histologic al evidence of adnexal inflammation. The histopathologic finding of su ppurative hidradenitis suggests the existence of clinical bacterial fo lliculitis, furunculosis, or both of these.
