Macroscopic findings of the resected jejunal tumor. A Gray- and dark red-colored exophytic multicystic mass originating from the serosa aspect of the jejunum measuring 11.5 cm in maximal diameter. A small dark red solid tumor originated near the anal side of the cystic tumor measuring 2.1 cm in maximal diameter (arrow). B Formalin-fixed jejunal tumor. The tumor was not exposed to the mucosal aspect of the jejunum; however, there was significant thinning and shallowing of the mucosal layer in the muscle layer from which the large cystic mass developed. C The cut surface of the cystic tumor showed intratumoral hemorrhage and cystic degeneration and formed a multicystic lesion. Partially tan-white and myxomatous components were also observed. The small tumor showed a tan-white solid cut surface (arrow)
