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 a benign salivary gland tumor, occurring primarily in the parotid gland. It's incidence is 4% of all salivary gland tumors. The cytologic finding of Warthin's tumor is characteristic and it consists of sheets of oncocytes and scattered lymphocytes in the background of granular material. We reports three cases of Warthin's tumor showing characteristic cytologic findings. The patients consisted of two males and a female and their ages were 60, 73, and 69 years, respectively. All the lesions were in the parotid gland. The cytologic findings showed sheets of oncocytic epithelial cells and scattered lymphocytes in the back-ground of granular materials and many red blood cells. In one case, the back-ground was composed of many Inflammatory cells including lymphocytes, neutrophils and macrophages.

Initially described in 1929, Warthin's tumor is a benign neoplasm predominantly found in the parotid gland of the salivary glands. Warthin's tumor is synonymous for cystadenoma lymphomatosum, adenolymphoma, and cystadenolymphoma. This tumor usually causes minimal pain, but the patient may complain of tinnitus, pain in the ear, or deafness. The tumor is treated with surgical excision, which is easily performed due to the superficial location of the tumor. In our case, a 69-year-old man visited our clinic primarily complaining of swelling in the left parotid gland area. Computed tomography revealed well-defined margins of the tumor in the superficial lobe of the left parotid gland and heterogeneous contrast enhancement. We performed superficial parotidectomy, with the pathological examination confirming Warthin's tumor. We report a typical case of Warthin's tumor and a literature review.

Papillary carcinoma of thyroid is the most common thyroid carcinoma carrying better prognosis than the other thyroid carcinoma. Among the variants in the papillary thyroid carcinoma, the tall cell variant and diffuse sclerosing variants have more aggressive behavior than the classic papillary carcinoma. Recently, a new variant of papillary carcinoma has been reported which was named warthin-like tumor of the thyroid because of its close histologic resemblance to a tumor encountered in the salivary gland, carrying favorable prognosis. Since then, in English literature, a few cases have been reported, but in Korea have not been reported yet. We report a case of warthin-like tumor of the thyroid. A 38 year-old woman who had neck mass, was administered for thyroid surgery due to suspicious thyroid cytology. Right total thyroidectomy and left subtotal thyroidectomy with central compartment node dissection was performed. Histologic diagnosis was made as a Warthin-like tumor of the thyroid.

Extraparotid Warthin's tumor(EPWT) is a rare disease entity; its incidence is about 8% of Warthin's tumor(WT). The periparotid and upper cervical lymph nodes are the most predilection sites. The lymphoid tissue of WT can act like a regional lymph node, and the necrosis and inflammation within the tumor are well known. In our cases, both 81-year-old man and 58-year-old man were visited our clinic, presented with upper lateral neck mass that had been present for the last few months. We operated the excisional biopsy in level ll of neck. The pathologic examination was proven to be EPWT. We report the unique two cases of extraparotid Warthin's tumor with literature review.

Warthin's tumor is the second most common benign tumor of the parotid gland, which consists of epithelial and lymphoid components. Malignant change is known to be extremely rare. In Korean literature, only a case of low grade adenocarcinoma arising from Warthin's tumor was reported. For squamous cell carcinoma, there has never been reported in Korea. The authors report a case of squamous cell carcinoma arising from Warthin's tumor in a 77-year-old male, who was treated with primary resection. The patient is well without any recurrence or metastasis after 15 months of follow-up.

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.

The Warthin tumor is a benign neoplasm that occurs mostly in the parotid gland. The tumor frequently occurs in the tail of the parotid gland. A 75-year-old man was referred to Wonkwang dental hospital with a chief complaint of swelling on the right submandibular area. Numerous salivary stones were observed in the right submandibular gland on computed tomography (CT). And the two tumorous lesions were incidentally found in the parotid gland bilaterally. The tumorous lesions showed homogeneous enhancement on the CT and intermediate signal intensity on both T1- and T2-weighted magnetic resonance (MR) images. This tumorous lesions also showed contrast enhancement on fat suppressed T1 weighted MR images. We report common CT and MR features of this case of Warthin tumor in the parotid gland with literature review.

Warthin's tumor is composed of glandular and often cystic structures with a papillary cystic arrangement, lined by characteristic eosinophilic epithelium. The stroma contains lymphoid tissue. Between 5 and 10 percent of all parotid gland tumors are Warthin's tumor and occurs almost exclusively in the parotid gland. This tumor is much more common in men than in women (5:1). Histologically it is composed of epithelial and lymphoid tissue. The treatment of this tumor is surgical excision and seldom recur after removal. Recently, We had experienced a case of warthin's tumor of the parotid gland in a 66 year old male treated with surgical removal.

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.
