We report two cases of old intraabdominal hematoma preoperatively presenting as a malignant solid tumor. Case 1: A 58-year-old man hospitalized for a 7 cm left subphrenic tumor found in ultrasonography underwent surgery, although the tumor was not clearly linked to the gastric muscular layer in endoscopic ultrasonography, because the tumor was large and suspected of being a gastric submucosal tumor or splenic tumor in abdominal CT and MRI. Case 2: A 50-year-old man hospitalized for a 2 cm pancreatic tumor found in abdominal MRI underwent surgery even though tumor markers, blood sugar, and insulin were within normal range, because we could not exclude the possibility of a pancreatic tumor. The definitive diagnosis was old hematoma in both cases. Although neither case was symptomatic and each had a history of abdominal trauma, the old hematoma should be considered as differential diagnosis in the case of intraabdominal tumor with central bleeding or peripheral calcification.
