Four cases of actinomycosis were diagnosed by fine needle aspiration (FNA) cytology and eight more cases were detected during a review of FNA smears reported as inflammatory. The age of these 12 cases ranged from 20 to 61 years with a median of 35 years. The male to female ratio was 3:1. The common regions of involvement were cervicofacial in seven cases (58.3%), thoracic in three (25.0%) and abdominal in two (16.7%). Four of the seven cervicofacial cases presented with intra-oral masses; the thoracic lesions were pulmonary in location, and the abdominal lesions presented as bowel masses. The possibility of actinomycosis was not considered clinically in any case. The main reason for missed cytodiagnosis in two thirds of the cases appeared to be observer error. It is suggested that when the aspiration smear from a mass is found to be an inflammatory exudate rich in neutrophils, special efforts must be made to look for this microorganism.
通过细针穿刺（FNA）细胞学检查确诊了4例放线菌病病例，在对报告为炎症的FNA涂片进行复查时又发现了8例。这12例患者的年龄在20至61岁之间，中位数为35岁。男女比例为3:1。常见受累部位为颈部面部7例（58.3%）、胸部3例（25.0%）和腹部2例（16.7%）。7例颈部面部病例中有4例表现为口腔内肿物；胸部病变位于肺部，腹部病变表现为肠肿物。所有病例临床均未考虑放线菌病的可能性。三分之二病例细胞诊断漏诊的主要原因似乎是观察者误差。建议当发现肿物穿刺涂片为富含中性粒细胞的炎性渗出物时，必须特别留意查找这种微生物。
