title: Thyroid papillary carcinoma with unusual breast metastasis.
abstract: Breast metastasis from thyroid carcinoma is a rare occurrence. We report a case of immunohistologically proven breast metastasis from a thyroid papillary carcinoma. The association of primary breast carcinoma and thyroid carcinoma is noted and the usefulness of immunohistological techniques emphasised especially when histological assessment is difficult.
