The standard workup to detect metastatic PC usually includes the 99mTc-methylene diphosphonate bone scan (BS) and chest/abdomen/pelvis scan, or if available, the 18F-choline and gallium-68 prostate-specific membrane antigen (PSMA) positron emission tomography-computed tomography (PET/CT) or whole-body MRI [11]. Here, FOLH1 is linked to pachyonychia congenita.
