唾腺肿瘤针吸细胞学诊断组织类型可行性探讨

Viability Study on the Cytologic Diagnosis of Histologic Typings Seenin Tumours of the Salivary Gland with Needle Aspiration

对56例大唾腺肿瘤的病理切片和术前肿瘤针吸细胞涂片进行回顾性研究,多数多形性腺瘤、腺淋巴瘤、腺样囊性癌和粘液表皮样癌可以通过细胞形态确定组织学类型。个别不能诊断的是由于针吸细胞成份不足,如果多方向针吸和复穿可能提高诊断率。值得注意的是腺泡细胞癌误诊最多。

A retrospective investigation was made by the authors into the post-operative pathollogic sections and pre-operative cytosmears obtained from 56 cases of tumour of the major salivary gland gland to study the viability of the diagnosis of histologic types through needle-aspirated cytospecimens. The histologic typings of pleomorphic adenoma adenolymphoma and adenoid cystic carcinoma as well as mucoepidermoid carcinoma could be ascertained through the smears. The cause of individual smears of which diagnosis could not be made was due to the insufficiency in quantity aspirated by the needle. Thus, the rate of diagnosis could be expected to raise if centesis was made repeatedly and on a multi-direction basis. It was relatively easy to diagnose squamous cell carcinoma and adenocarcinoma, but the opposite was true in dealing with acinic cell carcinoma because it was well differentiated. As for the fusiform-cell carcinoma which had a coarse chromatin, careful observation on the nuclear morphology would help to differentiate it from sarcoma.
