To characterize the cytomorphologic features of pilomatrixoma.
Aspirate findings in nine cases of PMX were correlated with clinical data and subsequent histology. This relatively large volume of case material afforded an opportunity to test the cytologic criteria that have been proposed as diagnostic of pilomatrixoma in the case reports published previously.
Ghost cells, basaloid cells and calcium deposits were the features found to be most characteristic of PMX and were observed in all four cases in which a correct diagnosis was made originally.
The presence of ghost cells seems to be the key to recognizing PMX. These cells are visible in the majority of air-dried smears but seldom in alcohol-fixed smears. Adequate cytologic sampling and the routine use of both wet-fixed and air-dried smears should preclude an incorrect diagnosis.
描述毛母质瘤的细胞形态学特征。
对9例毛母质瘤的抽吸结果与临床数据及后续组织学进行相关性分析。这一相对大量的病例材料提供了一个机会，来检验先前发表的病例报告中提出的作为毛母质瘤诊断依据的细胞学标准。
鬼影细胞、基底样细胞和钙沉积是毛母质瘤最具特征性的表现，在最初作出正确诊断的所有4例病例中均有观察到。
鬼影细胞的存在似乎是识别毛母质瘤的关键。这些细胞在大多数空气干燥涂片中可见，但在酒精固定涂片中很少见。充分的细胞学采样以及常规使用湿固定和空气干燥涂片应可避免误诊。
