Dr. Seema Chadha, Dr. Shilpa Ruhela* and Dr. Rakesh Kumar
Papillary carcinoma of thyroid presenting as a metastatic midline anterior chest wall mass with silent primary lesion in thyroid is a rare event. This case is discussed because of diagnostic challenge faced by us in a case of 61yrs old male presenting as painless cystic midline anterior chest wall mass since 1 year with no other co morbidities. USG examination revealed a soft tissue cystic lesion in anterior chest wall, following which excision was done and histopathological examination confirmed metastatic papillary carcinoma of thyroid which was further supported by immunohistochemistry. On further evaluation, MRI neck was done which showed 0.6 x0.6cm lesion in lower pole of left lobe of thyroid. Patient underwent total thyroidectomy and histopathological examination confirmed follicular variant of micro papillary carcinoma of thyroid in background of autoimmune thyroiditis.
