ABSTRACT
Breast cancer rarely metastasizes to the thyroid gland. We report a case history of a 40-year-old patient with inflammatory breast cancer treated with neoadjuvant chemotherapy at surgery, followed by adjuvant radiotherapy and hormonal therapy. After 4 years of diagnosis and treatment, she presented with a metastatic thyroid relapse revealed clinically by an anterior cervical swelling, biologically by thyroiditis unimproved by replacement therapy, histologically by thyroid biopsy and radiologically by pet scan. The evolution was favorable with a very good clinical and metabolic response after 6 months of 2nd-line chemotherapy.
