Warthin's tumor (WT) is second most common neoplasm in the parotid gland and it can be accompanied by inflammation and necrosis. The chest wall inflammation may present a rapid and fatal clinical course and secondary to parotid abscess is extremely rare. An 81-year-old man came to emergency room complained of rapidly enlarged left parotid mass and inflammatory symptoms and signs around the upper lateral neck. We performed incision and drainage with adequate infection control. He was pathologically diagnosed as abscess. We report the unique and instructive clinical case with a literature review.

Fine needle aspiration biopsy cytology is a widely recognized and useful technique which can provide diagnosis in lesions of the head and neck, enabling appropriate management plans for individual patient to be made. Fifty one fine needle aspirates from salivary gland masses were examined. Four aspirates (8%) were inadequate for examination. Of the remaning 47 samples, 42 cases (82%) were benign lesions which consist of 30 pleomorphic adenoma(58%), 7 inflammatory lesion (14%), 4 Warthin's tumor(8%) and 1 benign lesion(2%). Two cases(4%) were atypical lesions. Three cases(6%) were malignant lesions consisting of 2 adenoid cystic carcinomas(4%) and 1 mucoepidermoid carcinoma (2%). The cytologic diagnoses were compared with the subsequent histologic diagnosis of surgical resected specimen in 24 cases. 19 cases of 21 aspirates from benign tumors were correctly diagnosed by fine needle aspiration cytology, with a specificity of 90%. All 3 aspirates from the 3 patients with malignant tumor were correctly diagnosed by fine needle aspiration cytology, with a sensitivity at 100%. Overall acurracy was 88%. Diagnostic error was encountered in adenoid cystic carcinoma, mucoepidermoid carcinoma and Warthin's tumor Correct histologic diagnosis was made in 86% of benign tumors(84% for pleomorphic adenoma and 100% for Warthin's tumor) and in 100% of malignant tumors.

We systematically reviewed the literature on the co-occurrence of squamous cell carcinoma (SCC) and Warthin's tumor (WT), thought to be quite rare, to help reduce misdiagnosis and improve treatment planning. For this systematic review, we searched for articles in the Web of Science and PubMed databases, analyzed relevant studies for forward and backward citations, and identified only articles reporting on the "co-occurrence" of WT and SCC. Of the 237 studies identified, 12 comprising 18 patients met the inclusion criteria, to which we added one study from our institution. Most WTs were associated with SCC in the parotid gland or cervical lymph nodes. Most patients (89.5%) underwent selective or radical neck dissection due to identification of lesions separate from the primary SCC. Despite its frequent co-occurrence with other neoplasms, WT in the parotid or cervical lymph nodes tends to be misdiagnosed as a metastatic node when SCC is observed as the primary tumor. Factors to consider in diagnosis and neck management include identification of an association other than growth or development by lymphangiogenesis and whether the patient is a smoker, a strong risk factor.

Benign salivary gland tumors have relatively lower incidence, but it have various histopathologic diagnosis and biological behavior. Authors analyzed retrospectively 77 patients with benign salivary gland tumor who were treated surgically and had the following results. The most frequent age group was 5th decade, and sex distribution was not specific. The most common location was parotid gland(75.3%) and submandibular gland(20.8%) was next. Histopathologically, the most common salivary gland tumor was pleomorphic adenoma(82.7%) and Warthin's tumor(8.6%) was next. An asymptomatic mass was the most common presentation. Duration of symptoms and signs were mostly under the 5years(90.9%). Diameter of tumors was mostly under 4cm(76.7%). Parotid gland tumors were treated mostly with superficial parotidectomy and submandibular gland tumors were treated mostly with submandibular gland resection. The most common complication was facial nerve palsy(9 cases).

We analyzed retrospectively the 74 patients with salivary tumors who were treated surgically at Chonbuk National University Hospital. The following results were obtained: 1) The most prevalent site was parotid gland and minor salivary gland is second in order. The most prevalent site of minor salivary gland tumor was palate. 2) Slow-growing painless mass was the most common chief complaints. 3) The most frequnet age incidence was 4th and 6th decades. 4) Sex ratio of male to female was 1:1.1, but in minor salivary gland tumor, female was more prevalent and sex ratio of male to female was 1:1.5. 5) Histopathologically, the most common salivary gland tumor was pleomorphic adenoma. Among the benign tumors, the pleomorphic adenoma was most common and Warthin's tumor was next. Among the malignant tumors, the mucoepidermoid carcinoma was most common and adenoid cystic carcinoma, adenocarcinoma were the next. 6) 59 patients with benign tumor and 15 patients with malignant tumor were treated with operative therapy. Among patients with malignant tumor, 12 patients were treated with postoperative radiation therapy. 7) Overall incidence of postoperative complication was 14.9% and the most common complication was transient facial nerve weakness and hematoma.

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.
