(A) The reconstructed CT image reveals a tumor of the esophagus, elongated from the upper to middle third esophagus, with diviation of trachea and partially surrounding ring of air. (B) The reconstructed CT image using air injection into esophageal lumen showed almost complete ring of air surrounding the mass except close to the esophageal orifice. (C) A handmade device which consisted of sterilized rubber cap connected to suction tube, attracted mass and pulled more than half of the mobile mass outside the esophagus, based on intraoperative finding. (D) Pathological examination revealed mature adipose tissue, not including increased mitotic activity or lipoblasts.

CT image showed a tumor, 10.6 x 5.7 cm in length, elongated from the upper to middle third esophagus, with diviation of trachea and partially surrounding ring of air (Fig. 1A). Therefore, CT image using air injection into esophageal lumen was performed for confirmation of the pedunclated mass and the CT scan showed almost complete ring of air surrounding the mass except close to the esophageal orifice (Fig. 1B). A handmade device which consisted of sterilized rubber cap connected to suction tube, attracted mass and pulled more than half of the mobile mass outside the esophagus (Fig. 1C). The final results of the pathologic examination showed an esophageal lipoma (Fig. 1D).
