Benign entities include peptic ulcers, acute or chronic pancreatitis, and Crohn's disease. In western countries, the most common malignant aetiology is colon adenocarcinoma, while in eastern countries it is gastric adenocarcinoma. The incidence of a malignant fistula is very low: they appear in only 0.3%–0.4% of patients undergoing surgery for a digestive neoplasm.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The most common clinical manifestations are feculent vomiting, abdominal pain, diarrhoea and weight loss.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">We present the case of an 80-year-old patient with a history of a cholecystectomy and a hiatal hernia operated by a posterior Toupet-type fundoplication. The patient presented for an outpatient colonoscopy for a microcytic anaemia study, in which, 25 cm from the anal verge, an elongated foreign body embedded at both ends (bone fragment) was observed, with the surrounding mucosa oedematous and erythematous (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>A). It was extracted in a second stage, 24 h later, using a foreign body forceps, and an abdominal computed tomography (CT) scan was performed showing a 45 × 38-mm mass in contact with the greater curvature of the stomach and splenic flexure of the colon that suggested communication between the lumen of both structures (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B). Clinically, the patient reported postprandial dyspepsia and anorexia, with a weight loss of 3 kg in 6 months.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0020" class="elsevierStylePara elsevierViewall">The study was completed with a gastroscopy in which a 3−4 cm lesion with a depressed central area and raised margins with an inflammatory appearance, suggestive of a fistula (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>C) was observed in the gastric corpus, with an endoscopic ultrasound in which a solid 40 mm × 40 mm mass was observed that encompassed the gastric wall and communicated with the colon. A further colonoscopy revealed a mucosa with multiple ulcerations and an impassable stenosis at the splenic flexure (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>D).</p><p id="par0025" class="elsevierStylePara elsevierViewall">The biopsies were consistent with a moderately differentiated adenocarcinoma of gastric origin (CDX2 and CK20 positive immunohistochemical study, with weakly positive CK7).</p><p id="par0030" class="elsevierStylePara elsevierViewall">Therefore, the patient synchronously presented a foreign body lodged in the sigmoid colon and a malignant gastrocolic fistula.</p><p id="par0035" class="elsevierStylePara elsevierViewall">The detection of foreign bodies in the colon is rare, since they are usually expelled spontaneously once they have reached it.

The patient died three months later.</p><p id="par0065" class="elsevierStylePara elsevierViewall">In conclusion, malignant gastrocolic fistulas are infrequent.
