Treitz, in lieu of a tumor of the pancreas (Fig. 2). With a sequential serial section on histologic examination, the tumor was contained in the small intestinal segment in which the intramural mass consisted of interlacing bundle of spindle cells and interlacing bundle formation (Fig. 2).
Serial sections showed an intramural mass consisting of bundle of spindle cells with interlacing bundle formation. There were mild nuclear atypia and scant mitosis(Arrow).
