Although signet-ring cell (SRC) adenocarcinoma is commonly seen in the stomach, it is a very rarely seen histologic entity in the\nbladder. It is difficult to distinguish primary SRC adenocarcinoma of the bladder from bladder metastasis of SRC carcinoma of the\nstomach only based on histological findings. In such cases, clinical findings and immunohistochemical studies may be helpful.We\npresent here a 48-year-old male patient presenting with hematuria and abdominal pain. Computerised tomography of the patient\nrevealed a gastric mass, peritoneal involvement, and thickening of the bladder wall, and histopathological analysis revealed SRC\nadenocarcinoma in both of the endoscopic biopsies taken fromthe stomach and bladder. Immunohistochemical analyses confirmed\nthe diagnosis of SRC adenocarcinoma of the bladder secondary to gastric cancer.
