Fibrolipoma is a well-recognized benign neoplasm composed of adipocytes transected by fibrous connective tissue, but large population studies on these neoplasms are lacking in veterinary medicine. We retrospectively searched for canine cutaneous and subcutaneous fibrolipomas submitted to the surgical diagnostic pathology service of the Athens Veterinary Diagnostic Laboratory (Athens, GA, USA) between 2017 and 2024. We retrieved 236 neoplasms from 64,560 biopsies. The median age of affected patients was 8 y (±2.8 y), with an average tumor size of 2.9 cm (±2.3 cm). The head was the location affected most commonly (31.9% of cases), followed by the carpal area (10.3%), elbow (9.9%), thorax (6.9%), and abdominal wall (5.6%). Most cases were classified as cutaneous (90%). Compared with the total number of biopsy submissions, castrated male (46.2%; = 0.013) and Labrador Retriever (23%; = 0.047) dogs were affected most often.
纤维脂肪瘤是一种公认的良性肿瘤，由被纤维结缔组织横断的脂肪细胞组成，但兽医学中缺乏对这些肿瘤的大规模群体研究。我们回顾性检索了2017年至2024年间提交给美国佐治亚州雅典市兽医诊断实验室外科诊断病理服务部门的犬皮肤和皮下纤维脂肪瘤。我们从64560份活检样本中检索到236个肿瘤。受影响犬只的中位年龄为8岁（±2.8岁），肿瘤平均大小为2.9厘米（±2.3厘米）。头部是最常受影响的部位（31.9%的病例），其次是腕部区域（10.3%）、肘部（9.9%）、胸部（6.9%）和腹壁（5.6%）。大多数病例被归类为皮肤型（90%）。与活检样本总数相比，去势雄性犬（46.2%；P = 0.013）和拉布拉多寻回犬（23%；P = 0.047）最常受影响。
