A 38-year-old man, with no history of malignancy, was found to have a 2 cm jugular lymph node, for which a lymph node tuberculosis was suspected. The specimen revealed a cystic structure lined by mature keratinizing squamous epithelium with a prominent granular cell layer consistent with a squamous inclusion cyst in a lymph node, but a metastatic squamous cell carcinoma could not be excluded. This is the first case report of a rapidly enlarging squamous inclusion cyst in a jugular lymph node. Our case demonstrates the diagnostic challenges related to a squamous inclusion cyst in cervical lymph node and serves to inform the readers to consider this lesion in the differential diagnosis for similar situations.

一名38岁男性，无恶性肿瘤病史，发现有一个2厘米的颈静脉淋巴结，怀疑为淋巴结结核。标本显示为一个囊性结构，内衬成熟的角化鳞状上皮，有明显的颗粒细胞层，符合淋巴结中的鳞状上皮包涵囊肿，但不能排除转移性鳞状细胞癌。这是颈静脉淋巴结中快速增大的鳞状上皮包涵囊肿的首例病例报告。我们的病例展示了与颈部淋巴结鳞状上皮包涵囊肿相关的诊断挑战，并提醒读者在类似情况的鉴别诊断中考虑这种病变。
