Oxyphilic (Hurthle) cells have abundant eosinophilic granular cytoplasms and occur in both benign and malignant neoplasms of the thyroid gland. Most published studies described mainly oxyphilic tumors of follicular type, and reports on oxyphilic papillary thyroid carcinomas are rare. The oxyphilic variant of papillary carcinoma differs from the classic papillary carcinoma in its more aggressive biological behavior. We report a case of oxyphilic papillary carcinoma exhibiting exclusively oxyphilic cells in a follicular pattern without papillary structures. The pattern of papillary carcinoma was confirmed by fine needle aspiration material and lymph nodal metastasis, both of which revealed typicaled papillary structures with characteristic nuclear features, psammoma bodies, and oxyphilic cytoplasm.

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.
