68Ga-PSMA PET/CT Images of Multiple Cutaneous Metastases in a Patient With Prostate Carcinoma: Complete Response to 177Lu-PSMA-617 Treatment.

ABSTRACT: Although distant cutaneous metastasis is an uncommon presentation of prostate cancer, it remains an important diagnostic consideration as an advanced disease and a poor prognosis. Herein we present a rare case of prostate cancer patient whose multiple cutaneous metastases were treated with 177Lu-PSMA-617 radioligand treatment. To our knowledge, it is the first report in which a complete response was seen with 68Ga-PSMA PET/CT scan after 177Lu-PSMA-617 radioligand treatment.
