Abstract

Ectopic intrathoracic thyroid is very rare and represents only about 1% of mediastinal tumors. Mediastinal mass in a patient with an otherwise early-stage breast cancer needs evaluation. If the mass is a metastatic lymph node, it changes the entire treatment plan and prognosis. Here, we describe a case of a 57-year-old female presenting with a lump in the right breast of 6 months. Tru-cut biopsy of the lump showed infiltrating duct carcinoma, Grade III, triple-negative. Staging workup showed a mediastinal mass in addition to the right breast mass and ipsilateral axillary lymphadenopathy. Biopsy from the mediastinal mass was suggestive of an intrathoracic thyroid.
