Two cases of pulmonary nodules associated with Mycobacterium intracellulare infection were initially interpreted as carcinomas of the lung after brush cytology specimens were reported to contain malignant epithelial cells. In both instances, the cells observed in the cytology specimens exhibited marked cytologic atypia. These cells were identical to those present in tumorlets adjacent to the granulomatous lesion. Tumorlets may thus represent a source of false-positive cytologic findings or constitute a type of microscopic neoplasms of the lung.
两例与胞内分枝杆菌感染相关的肺结节，在刷检细胞学标本报告含有恶性上皮细胞后，最初被诊断为肺癌。在这两例中，细胞学标本中观察到的细胞均表现出明显的细胞异型性。这些细胞与肉芽肿病变附近的微小结节中的细胞相同。因此，微小结节可能是细胞学假阳性结果的来源，或者构成一种肺部微观肿瘤。
