These<unk> s are difficult to differentiate from<unk>  adenocarcinoma. The lesions are usually ulcers with a ragged, thickened mucosal pattern on contrast radiographs. The diagnosis is typically made by biopsy at the time of endoscopy. Several endoscopic findings have been reported, including solitary ulcers, thickened<unk>  folds, mass lesions and nodules. As there may be infiltration of the submucosa, larger biopsy forceps, endoscopic ultrasound guided biopsy, endoscopic submucosal resection, or laparotomy may be required to obtain tissue. Imaging investigations including CT scans or endoscopic ultrasound are useful to stage disease. Hematological parameters are usually checked to assist with staging and to exclude concomitant leukemia. An elevated LDH level may be suggestive of<unk> .
