Nonpustular psoriatic lesions detected by Tc-99m HMPAO labeled granulocytes.
A patient with a fever of unknown origin was evaluated by abdominal SPECT using Tc-99m HMPAO labeled granulocytes and a triple detector camera. Although no abscesses were located, nonpustular psoriatic skin lesions were demonstrated incidentally on the reprojectional images. Psoriatic scales contain a chemotactic factor for leukocytes, and this is a likely explanation for the increased uptake of the radiotracer by psoriatic lesions.
