Fine needle aspiration cytology (FNAC) is generally characterized by a high diagnostic accuracy in differentiating non‐neoplastic/inflammatory lesions from neoplastic lesions of the salivary glands. Lymphoepithelial sialadenitis/myoepithelial sialadenitis is exceedingly rare in paediatric patients and is characterized by a diffuse, often bilateral, salivary gland enlargement and the differential diagnosis may sometimes be difficult. We report the case of a 10‐year‐old boy who presented with a swelling of the left parotid gland investigated by ultrasound salivary gland FNAC.

具有异染性基质的肌上皮唾液腺炎：诊断陷阱。细针抽吸细胞学评估小儿唾液腺肿胀一例

细针穿刺细胞学 (FNAC) 通常的特点是在区分非肿瘤性/炎症性病变与唾液腺肿瘤性病变方面具有较高的诊断准确性。淋巴上皮性唾液腺炎/肌上皮性唾液腺炎在儿科患者中极为罕见，其特征是弥漫性、通常为双侧唾液腺肿大，鉴别诊断有时可能很困难。我们报告了一个 10 岁男孩的病例，他通过超声唾液腺 FNAC 研究了左侧腮腺肿胀。
