An Additional Case Of Breast Tumor Resembling The Tall Cell Variant Of Papillary Thyroid Carcinoma

A type of breast tumor histopathologically similar to the papillary thyroid carcinoma has been described and named Breast tumor resembling the tall cell variant of papillary thyroid carcinoma. Because breast is not an uncommon site for metastasis and about 5% of all such cases are of the thyroid origin, it is important to be aware of the existence of mammary tumors that can closely mimic a thyroid tumor representing a dangerous diagnostic pitfall that can also lead to unnecessary clinical investigations. Here, we describe a singular case of Breast tumor resembling the tall cell variant of papillary thyroid carcinoma showing an amazing macroscopic and microscopic resemblance with thyroid tissue harboring a papillary carcinoma.
