RESUMO
Metastasis to the sternum from follicular thyroid carcinoma is very rare. Because of a resistance to radioactive iodine therapy, skeletal metastases from differentiated thyroid cancer are difficult to treat. The surgical resection of skeletal metastatic lesion can be a valuable complement to radioactive iodine therapy and it can offer cure with prolonged survival. We recently experienced a case of follicular thyroid carcinoma with metastasis to the sternum in a 60-year-old woman, who presented with anterior chest wall mass and pain. We present this case with a review of the literature.

Colorectal cancer with bone metastasis as initial manifestation is a very rare event. We have reported a case of rectal cancer presenting with sternal metastasis. A 30 year-old man was evaluated due to pain in the sternal area with a bulging mass. History and physical examination did not suggest any specific disease. A radionuclide bone scan revealed increased uptake in the sternal area, right 6th rib, and sacrum. Microscopic examination of a biopsy specimen from the sternum showed metastatic adenocarcinoma. A barium enema and CT scan of the pelvis suggested carcinoma of the upper rectum. Adenocarcinoma of the rectosigmoid junction area was demonstrated by colonoscopic examination with biopsy. He received palliative transverse colostomy for obstruction without further treatment.
