Warthin's tumor is a benign neoplasm that most frequently occurs in the parotid gland. Warthin's tumor shows a tendency of bilateral occurrence, but most of bilateral tumors occur at different time. It usually affects older man and grows slowly. Surgical excision is appropriate treatment for patients with Warthin's tumor and rarely recurs after removal. We report a rare case of bilateral Warthin's tumor which detected at the same time. A 54-year-old man had painless, slowly growing masses on the both mandibular angles. The masses were detected ten years ago. CT scan, ultrasonographic evaluation and fine needle biopsy was performed for preoperative diagnostic study. Superficial parotidectomy was done one after the other at ten-day intervals. After excision, histological examination revealed a mixture of ductal epithelium and a lymphoid stroma. The overlying surface of lymphoid tissue was covered with epithelial cells that was abundant of eosinophilic cytoplasm. Both masses were diagnosed as Warthin's tumor. Postoperatively, the patient did well and had no evidence of recurrence of tumor for 2 years follow-up period. Authors experienced a rare case of bilateral Warthin's tumor which detected at the same time. We recommend stepwise superficial parotidectomy at one or two-week intervals as treatment of bilateral Warthin's tumor.

Warthin's tumor is the second most common tumor of the parotid gland after pleomorphic adenoma. It is well known to occur as bilateral and multiple patterns. The incidence of extraparotid Warthin's tumor (EPWT) is about 2.7% to 12%, peri-parotid and upper cervical area are the most common sites. Warthin's tumor with synchronous intraparotid and extraparotid area is extremely rare, only a few cases have been reported. We report a-71-year old man with unilateral swelling of the parotid area and upper neck, pathologically confirmed Warthin's tumor with literature review.

Warthin's tumor is a benign and slow growing tumor found exclusively in the parotid gland or the periparotid lymph nodes. It mostly affects males between the age of forty to seventy years and is closely related with smoking history. Between January 1981 and June 1996, 42 patients underwent surgical excision of Warthin's tumor of the parotid gland; which made up 10.6% of all parotid gland surgeries(398 cases) during the same period. Their ages ranged from 36 to 75 years with a mean age of 56 years. There were 33 male and 9 female patients with a 4.3 : 1 male to female ratio. The majority of the tumors were situated in the parotid tail whereas one was in the deep lobe. Bilateral simultaneous involvements of the parotid gland were found in 4 patients(9.5%) ; therefore total of 46 parotid glands were involved. Four(8.7%) of the 46 parotid glands had multifocal tumors ranginging from two to three lumps. Tumor sizes varied from 1.5 to 6.0cm with mean diameter of 3.lcm. Of the 42 patients, 26(61.9%) were diagnosed preoperatively or peroperatively by means of CT scans, ultrasound, 99m-Tc. scan, fine needle aspiration cytology or intraoperative frozen section biopsy. Of the 46 tumors, 30 underwent a superficial(n=29) or total(n=1) parotidectomy and for 16 cases with tumors suspected preoperatively or peroperatively of being single Warthin's tumor, only enucleation was performed. No cases of recurrence were identified during the follow up period regardless of type of operation performed, however the postoperative complication rate was much higher in the parotidectomy group(33.3%) than in the enucleation only group(12.5%). We feel that an enucleation procedure may be appropriate for the patients with single Warthin's tumor.

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.
