Abstract

Prostate cancer is the most common cancer in males. The most common metastatic regions for prostate cancer are the lymph nodes and bone. Unexpected metastasis sites, such as the pituitary gland, larynx, and skin, have been reported which is associated with long survival. Gastrointestinal system involvement has been also reported as case presentations. Until 2014, duodenum metastasis was reported in three patients. Herein, we aimed to present a patient who had widespread bone metastasis, as well as isolated duodenum metastasis at diagnosis.
