摘要：
PSMA PET/CT is routinely used for the detection of prostate cancer (PC). However, increased PSMA-ligand uptake has been described in a variety of benign and malignant tissues. A 71-year-old man with biochemical recurrence of PC initially treated with radical prostatectomy was referred for PSMA-ligand PET/CT. Apart from 1 lymph node with intense PSMA-ligand uptake, suspicious for metastasis, disseminated PSMA-ligand-avid subcutaneous lesions were seen. Histopathology of 1 of these lesions revealed an epidermoid cyst. Physicians should remain cognizant of non-PC-related causes of increased PSMA-ligand uptake, of which this case represent yet another example.
