Known triad of primary tumors presenting in a synchronous fashion is a proven entity, as in MEN syndrome, linked with specific genetic alterations. However synchronous occurrence of an invasive ductal carcinoma in the breast and a papillary carcinoma in thyroid is an uncommon event sparsely reported in literature. The present study has dicusses the presentation, evaluation and management of such a case of dual malignancy. We hereby report a case of 55 year old female presenting to us with lump in the left breast which was cytological proven Infiltrating ductal carcinoma. On further evaluation with PET CT uptake study also showed increased uptake in the thyroid, FNAC from was suggestive of malignancy. The patient was subject to Left modified radical mastectomy and total thyroidectomy in the same setting. The patient’s recovery was uneventful and excised specimens were sent for HPE. The breast specimen showed infiltrating ductal carcinoma with SPR grade 3.Histopathology from thyroid nodule revealed the presence of Papillary carcinoma with chronic lymphocytic changes in the surrounding tissue. The synchronous presentation of dual primary malignancy in Thyroid and Breast is a rarely reported event and should be subject to thorough analysis as treatment options are different for two and may need to be managed accordingly.
