OBJECTIVE:
To investigate the imaging manifestations of 16-slice enhanced CT of parotid adenolymphoma in the parotid gland and the corresponding pathology,in order to improve the understanding of the CT imaging manifestations of parotid adenolymphoma in the parotid gland.
METHOD:
The enhanced CT characteristics of 34 cases of parotid adenolymphoma in the parotid gland confirmed by histological pathology were retrospectively analyzed.
RESULT:
There were totally 86 lesions in 34 cases, of which 12 cases with lesions in bilateral sides and 22 cases with lesions in unilateral side. Sixty-six lesions located behind and below the superficial lobe of the parotid gland. The lesions showed moderate to obvious enhancement at arterial phase, and the cystic region within the lesions showed no enhancement.
CONCLUSION
The relatively specific enhanced MSCT manifestations of parotid adenolymphoma in parotid gland include lesions located behind and below the superficial lobe of parotid gland unilaterally or bilaterally, sometimes exhibited as multiple masses, with clear edge, obvious enhancement and cystic degeneration inside.

Warthin's tumor is the second most common benign tumor of the parotid gland. Malignancy arising from Warthin's tumor is extremely rare, and only 29 cases have been reported. Diagnosis can be made prior to the surgery, but in many cases, the disease is detected through postoperative pathology report or by recurrence of the mass lesion. We report a case of polymorphous low grade adenocarcinoma arising from Warthin's tumor diagnosed by the excision of a parotid mass and treated by an additional surgery of superficial parotidectomy. The postoperative pathology report revealed no residual cancer cells and the patient is free of disease for 8 months since the operation.

Neurilemmomas are benign tumors that arise from the nerve sheath. Facial nerve neurilemmomas are uncommon, slow-growing neoplasms that occur anywhere along the course of the facial nerve. The majority of facial nerve neurilemmomas are intratemporal, with a few cases arising from the intraparotid portion. The clinical presentations are generally insidious and the nature of the disease depends on the location and extent of the tumor. They are difficult to diagnose preoperatively and are frequently misdiagnosed because of the variety of their clinical manifestations. Therefore, early and correct diagnosis and evaluation are necessary. Recently, we experienced two cases of facial nerve neurilemmoma with relatively good surgical result, involving the mastoid segment of the facial nerve and the main trunk of the facial nerve in the parotid gland. We reviewed the diagnosis, pathology, and treatement of this case, and report the cases with reviews of literature.

OBJECTIVETo study the pathological characteristics of salivary malignant myoepithelioma with characteristic multinodular architecture.
METHODSTo observe the histologic and cytologic characteristics of 19 cases of de novo salivary malignant myoepithelioma with multinodular growth pattern. Immunohistochemistry of calponin, SMA, S-100, GFAP, cytokeratin, PCNA was done on 11 cases and ultrastructure was observed on 3 cases.
RESULTS19 tumors presented characteristic multinodular growth pattern, mostly accompanied by central necrosis. Neoplastic nests invaded the surrounding normal tissue and tumor cells displayed a variety of pleomorphism. Epitheliod cell was the most predominant cell type. Tumor-related extracellular matrix formation was revealed among tumor cells. Immunohistochemical staining demonstrated that the tumor cells were positive for calponin, SMA, S-100, GFAP, AE1/AE3, CKH and PCNA. Myofilaments were found in neoplastic cell cytoplasm under the electron microscope.
CONCLUSIONHistologic and cytologic observation, immunostaining and ultrastructural study all supported the myoepithelial and malignant nature of the tumor.

A dermoid cyst of the head and neck region is a relatively infrequent occurrence and accounts for only 6.9% of all dermoid cysts. Its anatomical distribution is the orbit, floor of the mouth, other midline and nose in the order of frequency. A dermoid cyst of the parotid gland is extremely rare, and due to this and the absence of pathognomonic findings, it is often difficult to diagnose preoperatively. Thus thorough and careful examination including ultrasonic study is needed to evaluate this lesion. It must be differentiated from malignant tumors and other cystic lesions. Dermoid cysts usually recur after simple excision, so it is mandatory to excise it completely with a parotidectomy. This paper presents two cases of parotid gland dermoid cyst with a brief review of the literature.
