A captive, adult female Brent goose (Branta bernicla) with a history of severe feather picking by its mate, was presented with 0.5-2.5 cm skin nodules on the head and neck. Histologic examination revealed a well-delineated dermal mass that surrounded an intact feather follicle and was composed of lakes of proteinaceous fluid and fibrin with scattered foamy macrophages and multinucleate giant cells. No bacteria or fungi were identified with histology, microbial culture, or PCR. Sterile panniculitis is an infrequent finding in animals and traumatic panniculitis is rarely sterile.

圈养布伦特鹅中的无菌外伤性脂膜炎。

一只圈养的成年雌性布伦特鹅（Branta bernicla）的伴侣有严重的羽毛采摘史，头部和颈部出现0.5-2.5 cm的皮肤结节。组织学检查显示，皮肤周围有完整的毛囊，由完整的羽毛滤泡组成，由蛋白质液和血纤蛋白的湖泊组成，散布着泡沫状巨噬细胞和多核巨细胞。通过组织学，微生物培养或PCR未鉴定出细菌或真菌。无菌性脂膜炎在动物中很少见，创伤性脂膜炎很少是无菌的。
