Uninodular Fibromyxomatous Gastric Tumor Resected by Endoscopic Submucosal Dissection

Abstract

Esophagogastroduodenoscopy of a 45-year-old woman revealed a submucosal tumor in the gastric antrum. Endoscopic submucosal dissection of the tumor was performed. The histological findings revealed a fibromyxomatous tumor composed of myofibroblastic cells with no evidence of malignancy. The growth pattern of the resected specimen was not multinodular or plexiform. We therefore tentatively referred to the present tumor descriptively as a gastric uninodular fibromyxomatous tumor, stressing its singular nodularity. It was initially roughly 10 mm in size but grew over a period of 4 years. A uninodular plexiform fibromyxoma might increase in size but might not become multinodular if it remains small.

Plexiform Fibromyxoma of The Stomach: A Rare Case Report And Review of Literature

“…Conservative management, such as endoscopic resection, has been tried to treat PF. Together with our case, 12 patients underwent gastroscopic resection (3,4,13,14). The common features for the twelve cases are that the tumors are located in the super cial layer (mucosa or submucosa) of the gastric wall and are small enough (with a median size of 1.65cm, ranged from 0.8cm to 5cm) to be resected under gastroscopy.…”

Huge gastric plexiform fibromyxoma presenting as pyemia by rupture of tumor: A case report

“…Of the 13 new cases, 9 patients presented with abdominal signs or bleeding symptoms[ 4 , 6 , 7 , 9 - 12 , 15 ] in Table 1 . Others were detected on medical examination performed for other reasons, such as hematuria[ 12 ], pharyngeal discomfort[ 13 ], and weight loss[ 14 ]. From the literature with clinical manifestations available for 108 cases, 86 patients presented as nonspecific gastrointestinal complaints or gastrointestinal hemorrhage, which could indicate that these are the most common symptoms of gastric PF.…”
