Abstract:
Port-site metastasis is an extremely rare complication following minimally invasive oncologic surgery for prostate cancer. We present the case of a 74-year-old man who underwent robot-assisted laparoscopic radical prostatectomy followed by salvage radiotherapy. Despite treatment, he developed biochemical recurrence. However, there was no evidence of disease on CT and bone scan at a prostate-specific antigen of 4.6 ng/mL. Subsequently, 18 F-DCFPyL PET/CT revealed a solitary focus of intense uptake in the right rectus abdominis muscle that was felt to represent a port-site metastasis. Histopathologic evaluation with immunostaining following ultrasound-guided needle biopsy confirmed the presence of metastatic adenocarcinoma of the prostate.
