摘　　要：BACKGROUND Plexiform fibromyxoma(PF)is a rare mesenchymal tumor of the stomach.The clinical features of PF frequently include upper abdominal pain,abdominal discomfort,hematemesis,melena,pyloric obstruction and an upper abdominal mass.We herein report a case of PF resected by laparoscopic radical distal gastrectomy plus Roux-en-Y gastrojejunostomy.CASE SUMMARY The patient was admitted to hospital,due to a 1-wk history of an abdominal space-occupying lesion identified during a health examination.He underwent complete resection by laparoscopic radical distal gastrectomy plus Roux-en-Y gastrojejunostomy.During the operation,the tumor was located in the anterior wall of the gastric antrum(approximately 7 cm×6 cm×5.5 cm)and did not show evidence of invasion of the serosa.Histology showed that the tumor cells were oval fibroblast-like and spindle-shaped cells,with numerous thin-walled blood vessels and abundant myxoid stroma.Cellular atypia and mitosis were both rare.Immunohistochemistry showed that the tumor cells were immunoreactive for smooth muscle actin,S-100 and CD-10,but were negative for CD-117,CD-34,DOG-1,and ALK.In this case,S-100 was positive and no significant disease was observed during the follow-up period.CONCLUSION The fact that PF is a rare tumor with only a few cases in this region can lead to misdiagnosis of this entity and pose a real diagnostic challenge for general surgeons and pathologists when encountering such patients and differentiating PF from other primary tumors of gastric mesenchymal origin.Our report may help increase awareness of this rare,but important new disease entity.
