A 4-year-old Labrador Retriever was examined because of progressive left hind limb lameness involving the stifle. A villous synovial mass was evacuated by synovectomy. Initially, the macroscopic and histopathologic features suggested a malignant fibrosarcomatous process; however, further histologic studies revealed lesions consistent with pigmented villonodular synovitis. Nine months later, the dog developed a large retroperitoneal tumor, with metastasis to the lungs and liver. The dog was then euthanatized. By histologic and electron microscopic examinations, the tumor was found to be a primitive plasmacytoid lymphoma.
一只4岁的拉布拉多猎犬因涉及 stifle 的左后肢渐进性跛行而接受检查。通过滑膜切除术切除了一个绒毛状滑膜肿块。最初，宏观和组织病理学特征提示为恶性纤维肉瘤过程；然而，进一步的组织学研究显示病变与色素沉着绒毛结节性滑膜炎一致。九个月后，这只狗出现了一个巨大的腹膜后肿瘤，并转移至肺和肝脏。随后对这只狗实施了安乐死。通过组织学和电子显微镜检查，发现该肿瘤为原始浆细胞样淋巴瘤。
