Tumors In The Shoulder


In the first place, one of the causes of shoulder pain can be a malignant tumor or a benign tumor that is growing in the shoulder blade or the humerus bone. With this in mind, this can lead to a humerus fracture, which physicians consider a pathological fracture. In contrast, they distinguish this from a fracture, which is the consequence of trauma. Certainly, benign bone cysts are not uncommon. Benign myxomas can also be found in the shoulder area.

Unfortunately, on the other hand,  malignant tumors are also not uncommon. Indeed, osteosarcoma is one of the common malignant tumors. It often presents in a child or teenager. Clinically this type of tumor likes to grow in the arm or in the lower extremity. A malignant fibrous histiocytoma that originated in the shoulder blade (=scapula) is shown here.

Cancer from other areas can metastasize into shoulder

For one thing, other cancers can metastasize into the shoulder such as kidney cancer, breast cancer as well as prostate cancer. It seems like not infrequently they tend to metastasize into the humerus bone and the shoulder blade. About 18% of breast cancer patients develop humerus metastases (Ref. 5). Here is an example of a liver cancer having metastasized into the shoulder. Non-Hodgkins lymphoma can also metastasize into the humerus.

Usually there is pain in a shoulder with a metastasis or a primary bone tumor in the humerus or scapula. X-rays, CT, MRI scans, or bone scans might suggest a tumor. However, only tissue diagnosis such as a bone biopsy under CT guidance with histopathological analysis of the material will confirm the diagnosis. An orthopedic surgeon and likely an oncologist need to be consulted to help with the proper work-up and the appropriate treatment protocol including possible bone surgery.
