Abstract
A 68-year-old man presented with synchronous metastatic penile and prostate cancer. 68Ga-labeled prostate-specific membrane antigen-targeted ligand positron emission tomography/computed tomography (PSMA-PET/CT) revealed tracer uptake in inguinal, pelvic, and retroperitoneal metastases. Lymph node biopsies and immunohistochemical staining revealed that both cancers involved the lymph nodes and expressed PSMA. In the deposits of penile squamous cell carcinoma, PSMA expression was seen in tumor vessels and may explain the PSMA-PET/CT positivity of inguinal nodes involved in squamous cell carcinoma. The interpretation of imaging in synchronous tumors should take this fact into consideration.Entities:
