Gastric lipoma is considered a rare condition that may constitute a challenging diagnosis. A 51-year-old woman presented dysphagia and abdominal pain, and an upper digestive endoscopic study disclosed a gastric tumor located in the submucosa of the pyloric antrum. Conclusive diagnosis was established after repeated endoscopic biopsies, and the patient was subjected to an atypical gastrectomy, which evolved into a pyloric stenosis. This complication was appropriately corrected and the patient remains symptomless, under outpatient surveillance.

We report the case of a man with a diagnosis of invasive gastric adenocarcinoma associated with scattered osteoblastic metastases. This 65-year-old patient was admitted with nausea, vomiting and abdominal pain, in addition to loss of weight (13 Kg in 3 months). Upper digestive endoscopy revealed extensive infiltrating changes in the body of the stomach, and histopathologic data confirmed the diagnosis of a Borrmann IV gastric adenocarcinoma. Complementary exams were indicative of a gastric cancer with bone metastases, characterized by disseminated osteoblastic images of the scintigraphy of the skeleton. Palliative chemotherapy was the treatment of first choice. High serum levels of CA 19-9, CEA and alkaline phosphatase can constitute useful indicative tools of this challenging condition. Images from a scintigraphy study of the skeleton can characterize the type and extension of bone metastases. The aim of this case study is to report a case of a very uncommon condition, considering that disseminated osteoblastic metastases rarely develop in this kind of tumor.Key words. Adenocarcinoma. Bone metastasis. Gastric tumor. RESUMENPresentamos un caso de adenocarcinoma gástri-co infiltrante asociado con metástasis osteoblásticas diseminadas. Un paciente de 65 años ingresó con náu-seas, vómitos y dolor abdominal asociados con pérdida de peso (13 Kg en 3 meses). La endoscopia digestiva objetivó extensas alteraciones infiltrativas del cuerpo gástrico y los datos histopatológicos confirmaron el diagnóstico de adenocarcinoma gástrico Borrmann IV. Exámenes complementarios fueran indicativos de cán-cer gástrico con metástasis óseas, caracterizadas por imágenes osteoblásticas diseminadas de la cintilografía del esqueleto. Se le administró quimioterapia paliativa como primera opción. Se elevó CA 19-9, CEA y apareció fosfatasis alcalina en el suero un indicador útil del diagnóstico. La extensión y el tipo de metástasis óseas pueden ser imágenes de cintilografías del esqueleto. Este caso tiene como objetivo describir la presencia de metástasis osteoblásticas diseminadas que raramente son producidas por este tipo de tumor.Palabras clave. Adenocarcinoma. Metástasis óseas. Tumor gástrico.
