Core Tip

Core tip: Plexiform angiomyxoid myofibroblastic tumor is a rare benign mesenchymal tumor of stomach. Rarity of this kind of tumors and scarce review articles may cause underrecognition of this entity and pose a real diagnostic challenge, when differentiating between various intramural lesions. Clinical signs and symptoms are nonspecific or absent, radiological features often overlap, upper gastrointestinal endoscopy has a limited role because of intramural location. Endoscopic ultrasound yields opportunity to visualize and biopsy the tumor. Definite diagnosis requires histological and immunohistochemical analysis.
