Bladder cancer is one of the most common malignancies of the urinary tract. Cutaneous metastasis of bladder carcinoma is extremely rare with a limited number of cases, resulting mainly from iatrogenic seeding. Here, we present scan findings of cutaneous metastasis in a known case of carcinoma urinary bladder. The 18F FDG PET/CT scan revealed FDG avid nodular thickening of the skin and sub-cutaneous tissue with ulcerations involving anterior pelvic wall, walls of the scrotum and the base of the penis. Histopathology confirmed the diagnosis of cutaneous and subcutaneous metastasis.
膀胱癌是泌尿系统最常见的恶性肿瘤之一。膀胱癌的皮肤转移极为罕见,病例数量有限,主要由医源性播散引起。在此,我们展示一例已知膀胱癌病例的皮肤转移扫描结果。18F FDG PET/CT扫描显示皮肤和皮下组织有FDG摄取增高的结节状增厚,伴有溃疡,累及骨盆前壁、阴囊壁和阴茎根部。组织病理学证实为皮肤和皮下转移。
