Breast cancer in a male with thyroid-associated orbitopathy and subclinical hyperthyroidism: a rare occurrence.

We present a case of a biochemically euthyroid male with active moderately severe thyroid associated orbitopathy who was coincidentally found to have breast carcinoma. The relationship between thyroid disease and breast carcinoma is discussed. The authors recommend that an enquiry of any breast lump or abnormality should be undertaken in all patients with thyroid disease.
