Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a recently described distinctive gastric mesenchymal entity with a peculiar plexiform pattern, bland spindle cells and a myxoid stroma rich in arborizing blood vessels. In this study, we report a new case of this rare gastric tumor resected by laparoscopic and endoscopic cooperative surgery (LECS). A 39-year-old Japanese man was admitted with a gastric mass. Gastroscopy showed an elevated mass in the anterior wall of the gastric antrum. Endoscopic ultrasound examination revealed a focal hypoechoic lesion protruding into the lumen. A partial gastrectomy by LECS was performed, and the patient made an uneventful recovery and remains well 9 months later. The tumor in this case depicted all the typical histopathologic and immunochemical features of gastric PAMT (c-kit negative and smooth muscle actin-positive). Especially, it was characterized by multiple nodules protruding outward within the serosa. Therefore, it is important that the resection line is determined on the serosa to ensure the complete resection of these nodules together. |
