  • Warthintumor (WT), also known as adenolymphoma or papillary cystadenoma lymphomatosum, was described in 1895 for the first time. It is a common benign tumor of the parotid glands and the second most common neoplasm of the salivary gland, accounting for 5% to 14% of all parotid neoplasm. A 63-year-old man visited our clinic with the complaint of swelling on the right parotid gland. Physical examination showed a 3 cm, firm, well-circumscribed, painless mass on the right mandibular angle. Computed tomography imaging showed a $3.5{\times}2.0{\times}1.6$ cm well-defined cystic mass. WT is histologically characterized by bilayered, oncocystic cell, lymphoid stroma, and cystic space. With these typical cytomorphologic characteristics, the fine-needle aspiration cytology was performed as diagnostic tool before the surgery. The lymphocytes and oncocystic cell were not observed. The lesion was completely excised under general anesthesia. We diagnosed the case as WT, from the surgically excised specimen. We report on the case with a review of the literatures.

  • Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/nonneoplastic lesions in fifty-three cases and fatted in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.

  • Fine needle aspiration cytology has become a frequently used technique for the diagnosis of lesions in the head and neck. Fine needle aspiration cytology of the salivary glands were performed on 66 patients. In 59 patients with satisfactory samples, cytologic diagnoses were as follows; there were 47 benign lesions, including pleomorphic adenoma(20), Warthin's tumor(3), benign cystic lesion(4), Inflammatory lesion(4), lymphoid lesion(3), myoepithelioma(1), unspecified benign neoplasm (5), and unclassified benign lesion(7). There were 6 cases of undetermined malignancy and 6 malignant lesions including mucoepidermoid carcinoma(3), adenoid cystic carcinoma(1), carcinoma ex pleomorphic adenoma(1), and metastatic carcinoma(1) in cytologic diagnosis. In 25 patients, the cytologic diagnosis was correlated with histologic findings. The sensitivity of the benign lesion was 96% and the specificity was 82%. There was no false-positive diagnosis. The sensitivity and the specificity of pleomorphic adenoma were 75% and 95%, respectively. Some of Warthin's tumors were confused with benign cystic lesion due to frequent cystic change of the tumor. The sensitivity and specificity of the malignant lesions were 56% and 88%, respectively. There were three false negative diagnoses. Two mucoepidermoid carcinomas were correctly diagnosed by cytology. Two of three adenoid cystic carcinomas were misdiagnosed as benign tumors.

  • The authors present the fine needle aspiration cytology (FNAC) cytologic findings of a case of extranodal marginal zone B cell lymphoma (MZBCL), which featured abundant plasma cells and eosinophilic histiocytes arising in both parotid glands. A 49-year-old female presented with palpable masses in both parotid glands. She had been suffering from systemic lupus erythematosus and rheumatoid arthritis. The lesions were evaluated by FNAC and smears showed a small number of clusters of oncocytic cells with abundant eosinophilic granular cytoplasm and small nuclei, intermixed with small to medium-sized lymphoid cells containing round to lobulated nuclei, which suggested Warthin's tumor. Some of lymphoid cells had a plasmacytoid appearance, and some scattered large cells contained a large amount of eosinophilic cytoplasm. Bilateral superficial parotidectomy was performed and a histopathologic study indicated MZBCL with abundant plasma cells, intermixed with eosinophilic histiocytes. The presence of oncocytic cells and a mixture of lymphoid and plasma cells indicates Warthin's tumor, but the cytologic features of a relatively monotonous small to medium-sized lymphoid infiltrate suggest the possibility of MZBCL in the clinical setting of an FNAC study performed on a patient suffering from a connective tissue disease.

  • Lymphoid infiltration can be seen in some lesions such as Hashimoto's thyroiditis, subacute thyroiditis and several neoplasm of the thyroid. In case of malignancy, there are a few reports of lymphoid infiltration in the diffuse sclerosing variant of papillary carcinoma. But heavy lymphoid infiltraton without evidence of sclerosis is uncommon. We experienced a case of papillary oxyphilic carcinoma with massive lymphoid infiltration, which looks like Warihin tumor of salivary gland. However cytological feature of epithelial cells exhibit that of papillary carcinoma.

  • Objectives: Major salivary gland tumor mainly develops in the parotid gland and pleomorphic adenoma is a large percentage. The aim of this study is to get clinicopathologic characteristics of overall major salivary gland tumors and suggestions regarding surgical management through collective review of 315 cases. Materials and Methods: This is a clinicopathologic review of 315 cases of major salivary gland tumor who were treated surgically at Department of Surgery, Head and Neck Clinic, Pusan Paik Hospital, Inje University during the period of 18 years from 1980 to 1997. Analysis was performed regarding the incidence, classification, surgery and its complications, and survival rate of salivary gland cancer. Results : 1) Parotid gland was the most prevalent site of salivary gland tumor(78%) and submandibular gland(21%) was next in order. Benign tumors were 257cases(81%) and malignant tumors were 58 cases(19%). 2) Male to female sex ratio was 1:1.2, the most prevalent age group was 3rd decade and the second group was 4th decade. 3) Histopathologically, the most common benign salivary gland tumor was pleomorphic adenoma. Warthin's tumor was next common. Among the malignant tumors, mucoepidermoid carcinoma was most common, and the next were adenoid cystic carcinoma and acinic cell carcinoma. 4) In pleomorphic adenoma, superficial parotidectomy was performed in 129 cases, and extracapsular tumorectomy was performed in 3 cases. In non-pleomorphic benign tumor, tumorectomy was performed in 21 cases. In 40 cases of deep lobe tumor, total parotidectomy was performed in only 2 cases and deep parotidectomy was performed in 38 cases. 5) Surgical complications were facial nerve injury 19 cases, Frey syndrome 13 cases, and salivary fistula 3 cases. 6) Overall 5-year survival rate of salivary gland cancer was 63%. Conclusion: Postoperative recurrence rate is low in benign tumor, but high in cancer of salivary gland tumor. Surgical procedure should not be aggressive in benign tumor, especially in parotid tumor, but should be aggressive in malignant salivary gland tumors.

  • Mammary analogue secretory carcinoma (MASC) is a rare malignant tumor of the salivary gland, which was first described in 2010. In this case report, we describe a 62-year-old woman with a MASC of the parotid gland, who initially presented with an asymptomatic preauricular mass. At first, computed tomography (CT) and fine needle aspiration cytology were performed; these suggested a possible Warthin's tumor but also some suspicious malignant findings. For the main treatment, adequate parotidectomy was conducted via modified Blair incision to remove the tumor. Postoperative pathology report revealed a MASC of the parotid gland. Specific MASC findings were observed upon immunohistochemical examination.

  • Purpose: Basal cell adenoma of the salivary gland is an uncommon type of monomorphic adenoma. The most frequent location is parotid gland. It usually appears as a firm, mobile and slow-growing mass. Originally the term "basal cell adenoma" is described as a benign salivary gland tumor comprised of uniform appearing basaloid cells which are arranged in solid, trabecular, tubular, and membranous patterns. But the myxoid and chondroid mesenchymal like component as seen in pleomorphic adenoma is lacking in basal cell adenoma. We report a case of basal cell adenoma of parotid gland with review of the literatures. Methods: The 59-year-old female patient was referred to our department with a painless palpable mass in the left preauricular region for about 1 year. Movable and nontender subcutaneous mass was palpable. There was no evidence of cervical metastasis in computed tomography and ultrasonography. On fine needle aspiration cytology, pleomorphic adenoma was suspected. Under general anesthesia, superficial parotidectomy including tumor was performed. The biopsy result was basal cell adenoma. Results: Long-term follow-up for 54 months showed favorable result without evidence of recurrence except for temporary facial nerve weakness right after the surgery. Conclusion: Basal cell adenoma is the third most frequent benign tumor of the salivary gland, following pleomorphic adenoma and Warthin's tumor, although the incidence is low. The typical clinical feature of the basal cell adenoma is slowly growing, asymptomatic, and freely movable parotid mass. Basal cell adenoma should be also considered as a differential diagnosis of the parotid gland benign tumor.

  • Objectives: Angiogenesis is the process of new blood vessel development from preexisting vessel. The growth of tumor is dependent on angiogenesis. This study was aimed to determine the role of the VEGF expression and MVD(microvessel density) in salivary gland tumors and to analyze the correlation between the expression of VEGF/MVD, and clinical manifestation. Material and Methods: We analyzed the expression of VEGF and average MVD and neo-MVD in the 57 cases of salivary gland tumors by immunohistochemistry. Results: VEGF expression was higher in malignant tumors than in benign tumors. Average and neo-MVD were not different in benign tumor and malignant tumor. There was a tendency of positive correlation between VEGF expression and MVD but it was not statistically significant. Stage, T stage and recurrance rate were not correlated with VEGF expression, average-MVD and neo-MVD. Expression of VEGF, average-MVD and neo-MVD were significantly increased in Warthin's tumor compared with pleomorphic adenoma. Conclusion: Overexpression of VEGF has an important role in malignant salivary gland tumors.

  • Tumors of the parotid gland are the most frequently encountered salivary gland tumors. Knowledge of the histology and anatomy of the salivary gland is important when considering the histiogenesis of salivary gland tumors, requiring close cooperation between the pathologist and the surgeon. Most tumors are benign epithelial formations. Pleomorphic adenomas predominate. Superficial lobectomy is adequate treatment. When the tumor involves a deep lobe, total parotidectomy is indicated. Treatment of malignant tumors depends on the histology, its TNM stage and other factors. Total parotidectomy with lymph adectomy and radiotherapy are needed in case of high grade malignancy. In children, vascular neoplasias are the most frequent, followed by malignant tumors. Their histological features and treatment are the same as for adults. We reviewed 64 cases of the parotid tumors at Department of surgery, Dong-A University Hospital from July. 1990 to Jan. 1999 for the purpose of apprehension of parotid gland tumor by the clinical study and review. Over all sex ratio was 1:1.13(M:F), mean age was 38.9 years, mean size was 3.53cm. According to histologic findings of 64 cases, pleomorphic adenoma was 55(85.9%), Warthin's tumor was 3(4.7%), mucoepidermoid carcinoma was 3(4.7%), squamous cell carcinoma was 2(3.1%), acinic cell carcinoma was 1(1,6%). Post op. facial nerve palsy 16(25%), Frey's syndrome 11(17.2%) cases were happened. Hence, the clinical manifestation of pain, tenderness, facial N. palsy suggest malignant tumors.
