RATIONALE: Lymphoepithelial carcinoma (LEC) is a rare malignancy with the histopathological feature of undifferentiated carcinoma and an intermixed reactive lymphoplasmacytic infiltration. Although clinically significant because of its malignant nature, it is difficult to make a differential diagnosis by preoperative imaging. Here, we report 3 cases of primary LEC arising in the major salivary glands, which showed unusual imaging features unlike other malignant tumors. PATIENT CONCERNS: Our first case is a 44-year-old man with LEC in the right parotid gland, the second case is a 71-year-old woman with LEC in the right submandibular gland, and the third case is a 35-year-old woman with LEC in the right parotid gland...

A49 -year-old woman presented with a 3.5 cm mass in her right breast. Mammography revealed a lobular mass with poorly defined margins and no microcalcification. Ultrasonography showed a hypoechoic mass with an irregular margin. The tumor was diagnosed as breast carcinoma using a core needle biopsy. The patient underwent a modified radical mastectomy with sentinel lymph node biopsy, and received adjuvant chemotherapy. The tumor consisted of 2 types of carcinoma. The center of the tumor was solid-tubular carcinoma, and the periphery was acinic cell carcinoma(ACC)...

Myoepithelial cells (MECs) exist on the basal surface of acini in major exocrine glands, include myofilaments and various constructive proteins, and share characteristics with smooth muscle and epithelial cells. MECs project several ramified processes to invest acini, and possibly contract to compress acini to support the secretion by the glandular cells. However, the functional roles of MECs in salivary secretion are still unclear. We investigated morphological changes in immunostained MECs using the anti-α-smooth muscle actin (αSMA) antibody in operated or non-operated contralateral (NC) submandibular glands after partial or total resection...

OBJECTIVE: Marginal mandibular nerve paralysis is the most frequent complication of benign parotid tumor surgery and results in cosmetic deformity. The purpose of this study was to develop a new electroneurography method for marginal mandibular nerve paralysis using electroneurography (ENoG) and judge its usefulness for clinical practice. METHODS: Twenty-seven patients who underwent surgery for benign parotid tumor were enrolled. We proposed and use the mandibular angle method, in which the recording electrode was placed on the skin above the depressor anguli oris muscle while the reference electrode was placed on the skin of the parietal region, and percutaneous electrical stimulation was applied to enclose the mandibular angle that could measure the function of the marginal mandibular nerve solely...

First bite syndrome is a potential complication of surgery involving the infratemporal fossa, deep lobe of the parotid gland and parapharyngeal space. It is described as an acute and intense pain in the parotid region caused with the first bite of each meal. It is related to damage to sympathetic innervation of the parotid gland. Parasympathetic hyperactivation is believed to stimulate an exaggerated myoepithelial cell contraction causing pain. Usual analgesic treatments have poor results. Botulinum toxin type A causes parasympathetic nerve paralysis of the parotid gland and this fact would minimize salivation and decrease first bite syndrome...

Sialadenitis is an inflammation or infection of the salivary glands that may affect the parotid, submandibular and small salivary glands. Imaging findings vary among unilateral or bilateral salivary gland enlargement, atrophy, abscess, ductal dilation, cysts, stones and calcification. Imaging can detect abscess in acute bacterial suppurative sialadenitis, ductal changes with cysts in chronic adult and juvenile recurrent parotitis. Imaging is sensitive for detection of salivary stones and stricture in obstructive sialadenitis...

BACKGROUND: Salivary gland tumors are an uncommon entity and its histopathology is highly varied due to heterogeneous cellular composition. The role of the preoperative fine-needle aspiration cytology (FNAC) remains controversial. The purpose of this study is to compare the cytologic findings of salivary gland lesions with the histologic diagnoses, in order to assess the usefulness and accuracy of fine-needle aspiration cytology in the diagnosis of parotid gland tumors. METHODS: A retrospective study was performed, regarding patients (n = 65) submitted to surgery for the treatment of parotid gland disease, who had performed preoperative FNAC, in our department between 2002 and 2012...

Axillary lymph node evaluation remains essential in breast cancer surgery, first as a prognostic factor, because it indicates the degree of dissemination of the disease to the main lymphatic drainage basin of the breast, and, on the other hand, as an element of preventing the local relapse. In the era of the sentinel lymph node, complete axillary lymphadenectomy, considered valuable until recently, but as therapeutic and diagnostic, has become an intervention performed increasingly rare in selected cases. Axillary lymphatic tissue resections are accompanied by morbidity (lymphedema, paresthesia, limitations of arm movement) and symptom magnitude is proportional to the extension of the intervention...

The vast majority of benign tumors of the cerebellopontine angle, temporal bone, and parotid gland can be successfully resected without permanent injury to the facial nerve. Malignant tumors or recurrent disease may require facial nerve sacrifice, especially if preoperative facial paresis is present. This article will present case examples of the various methods to reconstruct facial animation after lateral skull base resections that require sacrifice of cranial nerve VII, and the associated mimetic facial musculature...
