Tests and procedures used to diagnose desmoplastic small round cell tumors include:
Removing a sample of tissue for testing. A biopsy procedure involves removing samples of cells from the tumor. Doctors can collect tissue samples during surgery or with a needle that's passed through the skin.
Tissue samples are sent to a laboratory for testing. Mayo Clinic's Molecular Anatomic Pathology Laboratory conducts technical and specialized testing, including molecular genetic tests. Using the latest technology, doctors in the lab are able to make an accurate and timely diagnosis.
Imaging tests. Imaging tests may be used to give your doctors a better indication of the extent of your cancer and whether it involves nearby structures.
Imaging tests may include ultrasound, CT, MRI and positron emission tomography (PET).
Desmoplastic small round cell tumors are a type of soft tissue sarcoma.
