Granulocytic sarcoma (GS) is an uncommon and localized extramedullary tumor composed of immature granulocytic cells. Most GS reported in large series were not associated with overt acute myelogenous leukemia. Gastric perforation occurred during prednisolone therapy in a 72-year-old Japanese male with a four-month history of a myelofibrosis-like state. Subtotal gastrectomy was performed for a suspected gastric ulcer perforation. Gastric histologic, immunohistochemical and cytochemical examination revealed diffuse infiltration by sheets of myeloblasts and promyelocytes with scant or moderately abundant cytoplasm including a few eosinophilic myelocytes. Bone marrow study done in one month after the operation disclosed refractory anemia with excess of blasts (RAEB). Leukemic transformation occurred two months later, and a subcutaneous tumor appeared on the forehead. The forehead tumor predominantly consisted of myeloblasts without evidence of maturation. Both the stomach and forehead tumors were examined immunohistochemically with a panel of monoclonal antibodies (LCA, L26, MT1, UCHL1, OPD4, LN-1, LN-2, LN-3, MB1, Leu-M1, PM) and polyclonal antibodies (lysozyme, alpha 1-antitrypsin, alpha 1-antichymotrypsin, S-100 protein, lactoferrin), as well as naphthol-ASD-chloroacetate esterase staining to investigate and characterize the reliable marks for GS, and the patient was diagnosed as GS. We found that gastric GS may occur in a myelofibrosis-like state followed by RAEB of myelodysplastic syndrome and that naphthol-ASD-chloroacetate esterase staining and immunohistochemical detection of MT1, lysozyme, and alpha 1-antitrypsin were the most reliable markers for confirming the diagnosis of GS.

Gastric perforation into the pericardium is an extremely rare but lethal condition. Only a few case reports have been described in the literature. It is difficult to diagnose these patients with clinical evaluation. Accurate and immediate diagnosis of the intestinal perforation is vital. Herein, we present a 56-year old female patient with gastric perforation into the pericardium due to benign gastric ulcer diagnosed with computed tomography (CT). We also emphasized the imaging findings in the diagnosis of intestinal perforation into the pericardium.

Nissen fundoplication is a safe and effective procedure for gastroesophageal reflux. Gastric ulceration leading to perforation is an uncommon late complication with a mechanism of action that is poorly understood. A 40-year-old male presented 3 years following his fundoplication with a perforated ulcer in the upper body of the stomach. The patient admitted ibuprofen use leading up to the perforation. The perforation was successfully repaired via laparoscopy, with good postoperative outcome. Gastric ulcer perforation post-fundoplication is a rare late outcome. Gastric perforation may have been precipitated by the use of non-steroidal anti-inflammatory drugs (NSAIDs) in concert with the vascular mechanical changes caused by this procedure. A review of the literature reveals only a handful of accounts of gastric ulcers or perforations as a late outcome. Of note, many of these perforations occur in the upper stomach and in tandem with NSAID use.
