The secondary amyloidosis (AA type), a complication of inflammation or infection, is caused by the deposition of serum amyloid protein A in various organs. The clinical manifestations of amyloidosis are various according to involved organs. The gastrointestinal tract is one of the commonly affected organs. However, the endoscopic findings of gastrointestinal amyloidosis are nonspecific, and symptoms are diverse. Hepatic involvement of amyloidosis rarely leads to hepatic dysfunction, threfore is not a clinical concern. We report a 54-year-old women with intestinal tuberculosis whose major symptom was watery diarrhea lasting several months. The amyloid deposits were histologically proven in the rectum of which mucosa showed redness and swelling endoscopically and hepatic involvement of amyloidosis was suspected on abdominopelvic CT scan. After anti-tuberculosis medication for 6 months, abdominopelvic CT scan showed resolution of hepatic involvement and colonoscopy revealed improvement of redness and loss of vascularity of the rectum.
