[Rare gastroenterologic finding as a cause of hypochromic microcytic anemia]. / Seltener gastroenterologischer Befund als Ursache für eine hypochrome mikrozytäre Anämie.

CASE HISTORY: A 66-year-old woman suffering from skin paleness and weakness presented an increasing hypochromic, microcytic anemia. Diagnostic: In an ambulant setting a capsule endoscopy of the small intestine was carried out because of multiple polyps of the colon (colonoscopy) in addition to non-invasive (Hämoccult-Test) and invasive (gastroscopy) diagnostic. The patient was then admitted to hospital to clarify a suspicious ulcer of the small bowl. According to biopsies taken via balloon enteroscopy, an adenocarcinoma of the small intestine was diagnosed. THERAPY AND CLINICAL COURSE: After staging and exploratory laparotomy, histology findings showed an advanced tumour stage. A palliative chemotherapy, analogue to colon cancer treatment, was conducted. CONCLUSION: Small bowel diagnostics should be carried out if the aetiology of an anemia is not certain with an existing polyposis of the colon. Individuals with personal or family history of cumulative colorectal adenomas should undergo assessment for an adenomatous polyposis syndrom.
