Cutaneous Metastasis From Prostate Cancer on Posttherapeutic 177 Lu-Prostate-Specific Membrane Antigen Scan

In this note, we aim to present a patient with a known case of prostate cancer with widespread metastasis to the skeleton and liver who has undergone several cycles of chemoradiotherapy. The patient received 2 doses of 177 Lu-prostate-specific membrane antigen therapy, in which several zones of uptake were detected on the thoracic wall compatible with cutaneous metastatic lesions of prostate cancer.
