Case Study 16
Bone marrow tissue sections are superior to bone marrow smears for the detection of metastatic tumors. Metastatic tumors tend to clump together and are frequently associated with bone marrow fibrosis, as in this case. Cytochemical and immunohistochemical techniques are useful in distinguishing metastatic neoplasms from bone marrow malignancies and in subclassifying the metastatic tumors. Common tumors that metastasize to bone include: lung , gastrointestinal, breast, prostate, renal, pancreas and thyroid carcinoma. Of these, pancreatic carcinoma is known for its poor prognosis. Tumors arising in the body or tail can present clinically as a solitary bone metastasis.
