The document details the medical history and diagnosis of a 59-year-old male patient who presented with symptoms indicative of upper gastrointestinal bleeding and severe anemia due to a pre-pyloric adenocarcinoma of the stomach. Despite a lack of family history of malignancy, the patient's smoking history and specific symptomatology led to this diagnosis. The patient underwent investigations, received treatment for anemia, and subsequently had palliative surgical intervention without complications.
