A fine needle aspirate of a neck mass in a 79-year-old man with a previous laryngectomy for squamous cell carcinoma was submitted for examination. In addition to cytologic findings of squamous cell carcinoma, there were numerous birefringent crystals of varying shapes and sizes. Energy dispersive x-ray analysis confirmed that these crystals were barium sulfate. Recognition of barium sulfate crystals in a fine needle aspiration or other cytologic specimens is important since barium granulomas may mimic neoplasms clinically. Barium sulfate may also indicate rupture of an organ or the presence of a fistula.
一位79岁男性因鳞状细胞癌行喉切除术，其颈部肿物的细针穿刺样本被送检。除了鳞状细胞癌的细胞学表现外，还发现了许多形状和大小各异的双折射晶体。能量色散X射线分析证实这些晶体为硫酸钡。在细针穿刺或其他细胞学标本中识别硫酸钡晶体很重要，因为钡肉芽肿在临床上可能会与肿瘤相似。硫酸钡也可能提示器官破裂或瘘管的存在。
