Sarcoidosis of the axial skeleton.

Sarcoidosis of the bones in the hands and feet is not uncommon. However, sarcoidosis involving the axial skeleton is unusual. The authors present the case of a 37-year-old man with sarcoidosis who developed low-back pain. Radionuclide bone scan demonstrated abnormalities in the pelvis, spine, and scapulae. A bone scan directed open biopsy of an abnormality in diagnostic tissue from the ilium.
