Abstract

A 58 years old male patient presented with a left cervical metastasis of a poorly differentiated squamous cell carcinoma, which was diagnosed by fine needle aspiration cytology. Clinical examination, MRT scans and panendoscopy did not detect the primary tumour site. The positron emission tomography localized an uptake of FDG in the left sided base of the tongue. The patient underwent an ipsilateral modified radical neck dissection and a lateral pharyngotomy. In the left tongue base an induration was palpable which was resected with security distance. The histopathological examination showed a poorly differentiated squamous cell carcinoma with a largest extension of 5 mm x 10 mm.

摘要

一名58岁男性患者出现低分化鳞状细胞癌左颈部转移，通过细针穿刺细胞学检查确诊。临床检查、磁共振成像扫描和全身内镜检查均未发现原发肿瘤部位。正电子发射断层扫描显示左侧舌根有氟代脱氧葡萄糖摄取。患者接受了同侧改良根治性颈清扫术和外侧咽切开术。在左侧舌根可触及硬结，将其连同安全切缘一并切除。组织病理学检查显示为低分化鳞状细胞癌，最大范围为5毫米×10毫米。
