腮腺分泌性癌1例并文献复习

Parotid Secretory Carcinoma: One Case Report and Literature Review

腮腺分泌性癌是一种少见的低度恶性唾液腺肿瘤,70%发生于腮腺。本文回顾性分析1例腮腺分泌性癌的临床资料,并结合国内外文献进行复习和讨论。该病例的临床表现为5年前无意间发现、渐进性生长的无痛性肿物。超声检查:左侧腮腺内探及到多个不均质低回声团,内部回声不均匀,形态规则,边界欠清晰,内可见血流信号。CT检查:病变呈浅分叶状,可见囊性低密度区及实性结节影,增强后不均匀强化,边界清晰。本文通过总结腮腺分泌性癌的临床表现及影像学特点,为临床诊断提供帮助。

Parotid secretory carcinoma is a rare,low-grade malignant salivary gland tumor,with 70%occurring in the parotid gland.Through the clinical data of a parotid gland secretory carcinoma were retrospectively analysis,combined with domestic and foreign literature reviewed and discussed.The patient's clinical presentation was an unintentional and painless mass 5 years ago.Ultrasound examination:the left parotid gland explored multiple heterogenous hypoechomasses,uneven internal echo,regular morphology,poorly clear boundary,and visible blood flow signal.CT examination:CT showed the lesion as shallow lobulated,with cystic low density area and solid nodular shadow,uneven enhancement and clear border after enhancement.Summarize the clinical manifestations and imaging features of parotid secretory carcinoma for clinical diagnosis.
