Two cases of unusual benign tumors of the neck are described, both of which were initially misdiagnosed on cytology as carcinomas. Fine-needle aspiration findings in each case demonstrated a pleomorphic population of cells including bizarre multinucleated giant cells, the latter raising the false impression of malignancy. However, on review the cytological appearances of the tumors, a pleomorphic lipoma and a carotid body tumor, were characteristic. The correct diagnosis in each case would have been made or suggested if the pathologist had been familiar with the cytologic features characteristic of the lesion and the differential diagnosis of the head and neck tumors. In addition, the point is made that adequate clinical information is essential for the pathologist if all relevant conditions are not to be missed in the differential diagnosis.
本文描述了两例颈部罕见的良性肿瘤，这两例最初在细胞学检查中均被误诊为癌。每例细针穿刺结果均显示细胞形态多样，包括奇异的多核巨细胞，后者给人造成恶性肿瘤的错误印象。然而，回顾肿瘤的细胞学表现，一例为多形性脂肪瘤，另一例为颈动脉体瘤，均具有特征性。如果病理学家熟悉病变的细胞学特征以及头颈部肿瘤的鉴别诊断，那么在每例中都能做出或提示正确的诊断。此外，还指出如果在鉴别诊断中不漏诊所有相关情况，那么足够的临床信息对病理学家来说至关重要。
