Distinctive microscopic findings in enlarged axillary lymph nodes removed during modified radical mastectomy in a 76-year-old woman with a previous ipsilateral total shoulder joint replacement are described. The sinuses of the lymph nodes were distended by numerous large macrophages that had abundant granular eosinophilic cytoplasm. Periodic acid-Schiff staining was positive, and polarization microscopy revealed birefringent particles of polyethylene. These findings were diagnostic of the reactive lymphadenopathy that is seen uncommonly in lymph nodes draining large joint prostheses.
描述了一名76岁曾行同侧全肩关节置换术的女性在改良根治性乳房切除术中切除的肿大腋窝淋巴结的独特显微镜检查结果。淋巴结的窦被大量巨噬细胞扩张，这些巨噬细胞具有丰富的颗粒状嗜酸性细胞质。高碘酸-希夫染色呈阳性，偏振显微镜检查显示聚乙烯的双折射颗粒。这些发现诊断为反应性淋巴结病，这种情况在引流大型关节假体的淋巴结中罕见。
