Abstract

PURPOSE
Warthin-like papillary carcinomawas named owing to its close histologic resemblance to a tumor encountered in salivary gland, and this tumor is a variant of papillary thyroid carcinoma. Among the variants of papillary thyroid carcinoma, the tall cell variant and diffuse sclerosing variant have more aggressive behavior than the classic papillary carcinoma. But Warthin-like papillary carcinoma arises in a background of thyroiditis and it behaves in an indolent fashion. Since then, a few case have reported in Korea. We report here on the clinicopathologic features of five cases of warthin-like papillary carcinoma.
METHODS
From Jan. 1996 to Feb. 2008, five patients who were diagnosed with Warthin-like papillary thyroid carcinoma at YUMC were retrospectively reviewed.
RESULTS
All 5 patients whose pathologic features were warthin- likepapillary thyroid carcinoma were women (age range: 34~60 years). The tumor size ranged from 0.6 to 2.4 cm. 3 tumors were confined to the thyroid, but 2 tumors had invaded the strap muscles. 3 of the 5 tumors arose in a background of lymphocytic thyroditis. Central nodal metastases were identified in 2 cases. But no lateral nodal or distant metastasis had occurred. The mean duration of follow- up was 16.5 months (range: 5~50 months). 1 patient died because of lung cancer, and there was no recurrence for the other 4 cases during the follow-up period.
CONCLUSION
Although the long-term follow-up data on patients with Warthin-like papillary carcinoma is not available, the clinicopathologic data does not show that Warthin-like papillary carcinoma is any more aggressive than the usual papillary carcinoma.
