BACKGROUND
Extraskeletal osteosarcoma, unlike skeletal osteosarcoma, is a rare malignant mesenchymal tumor with a soft tissue primary that has been reported to occur in a variety of soft tissues.
CASE DESCRIPTION
The case is a 14-year-old, unneutered male Miniature Pinscher, weighing 6.7 kg, who had been treated medically for more than 5 years with a management strategy of puncture extirpation of a salivary gland cyst in the mandible; 1 month earlier, the fluid retention could not be removed, and after a computerized tomography scan showed no lesion in the mandible adjacent to the mass lesion, surgical resection was performed.
CONCLUSION
Previous reports of extraskeletal osteosarcoma from the salivary glands in dogs have been rare. However, treatment of a salivary gland cyst in the mandible by long-term puncture extirpation may be a potential predisposing factor for the development of extraskeletal osteosarcoma around the mandible.
背景
不同于骨骼骨肉瘤，发生于各种软组织的骨外骨肉瘤是一种罕见的软组织恶性间叶组织肿瘤。
病例描述
该病例为一只 14 岁、未去势的雄性迷你品犬，体重 6.7 千克。曾因下颌唾液腺囊肿接受过长达 5 年的医学治疗，治疗方案为经皮切除术；1 个月前，囊液无法清除，计算机断层扫描显示肿块邻近的下颌无病变，随后进行了手术切除。
结论
先前有关于犬唾液腺骨外骨肉瘤的报道较为罕见。然而，下颌唾液腺囊肿的长期经皮切除术可能是下颌周围发生骨外骨肉瘤的潜在诱发因素。
