Delayed onset bleeding

Abstract: A 50−year−old woman was referred to our hospital for evaluation of a 3−cm submu− cosal mass at the gastric cardia. Gastric endosonography performed using a curved linear−array echo endoscope (GF− UCT240; Olympus Optical Co., Tokyo, Japan) revealed a well−circumscribed, heterogenous, echo−poor mass, 30 mm ” 26 mm in size, arising from the fourth sonographic layer. Two passes were made into the tumor with a 19−gauge Trucut needle (Quick−Core, Wilson−Cook, Winston−Salem, North Carolina, USA) to obtain a 9−mm−long tissue core (Figure 1). There was no immediate bleeding. Check endoscopy at 24 hours also did not reveal any local bleeding. The histopathological and immunohistochemical findings were consistent with a diagnosis of gastric stromal tumor.
