Because there is usually little to distinguish these tumors in their clinical behavior from epithelial neoplasms, the diagnosis is seldom made until the specimen is examined in the pathologic laboratory. This discussion deals with a general consideration of the problem and a review of the cases of mesenchymal tumors of the stomach encountered at the Detroit Receiving Hospital during the past twenty-six years.
