Plain-English summary
A 6-year-old male black Labrador retriever was brought in because he had been losing patches of hair for 12 weeks. A skin biopsy revealed that he had a condition called sebaceous adenitis, which affects the glands that produce oil in the skin, along with another issue called panniculitis, which is inflammation of the fat layer under the skin. Over the course of a year, some hair grew back in certain areas, but the hair loss in the center of the larger patches remained permanent.

Abstract
A 6-year-old entire male black Labrador retriever was presented with nonpruritic multicentric, well-demarcated alopecia of 12-weeks duration. Skin biopsies from the margins of alopecic regions showed sebaceous adenitis and sub-follicular panniculitis. Biopsies from alopecic areas showed severe follicular atrophy with residual fibrous tracts, loss of sebaceous glands and lymphohistiocytic panniculitis beneath individual atrophic hair follicle groups. These features differed from previous reports of pilosebaceous diseases of dogs and appeared to extend the spectrum of inflammatory patterns in presumed immune-mediated adnexal diseases of this species. During the 12-month follow-up, there was partial hair regrowth without treatment but alopecia was permanent in the centre of larger lesions.
