摘      要：BACKGROUND Intercalated duct lesions(IDLs)are considered relatively benign and rare tumors of salivary glands,that were only described *** histopathological appearance may range from ductal hyperplasia to encapsulated adenoma with hybrid patterns of both *** is thought that IDLs may be the precursor for malignant proliferations,therefore their correct diagnosis remains crucial for proper lesion *** is the first reported IDL case arising from the accessory parotid gland(APG),which stands for less frequent but higher malignancy rate tumor developmental *** SUMMARY A 24-years-old male with no accompanying diseases was referred to the hospital with a painless nodule on the right *** physical examination,the stiff,immobile,and painless mass was palpable in the anterior portion of the right parotideomasseteric region,just superior to the parotid *** examination demonstrated 1.5 cm×1.0 cm hypoechogenic mass on the anterior part of the right parotid ***-guided fine needle aspiration cytology,followed by liquid-based fine needle aspiration biopsy were ***,the results were uninformative.A contrast-enhanced magnetic res-onance imaging(MRI)of the parotid was obtained,demonstrating a 1.5 cm×1.0 cm×0.5 cm tumor with high intensity capsule together with low intensity core in the very anterior part of right superficial lobe,situated in the *** MRI features were uncharacteristic to common parotid tumors,therefore surgical resection followed *** histopathological examination,the final diagnosis of hybrid IDL was *** Fine needle aspiration biopsy might not always be diagnostic,and given the malignant potential,the surgical resection of such lesion remains the treatment of choice.
