Granular Cell Tumor of the Esophagus: Analysis of five cases with review of four additional cases in Korean literature / 대한소화기내시경학회지

Granular cell tumor(GCT) has been identified in all organ systems, most often in the oral cavity and subcutaneous tissue. GCT of the esophagus has been considered rare. However, this neoplasm is being recognized with increased frequency since the use of fiberoptic endoscopy has become widespread. We report 5 cases of granular cell tumors involving the esophagus, all of which were incidentally found. Four additional cases of GCT which appeared in the Korean literature were reviewed.

Pseudolipomatosis of the Gastrointestinal Mucosa: Report of 6 cases with analysis of possible factors involved during endoscopic procedure

Pseudolipomatosis of the colonic mucosa has been recognized as a lesion featured with aggregations of gaseous spaces in the lamina propria, but its pathogenesis remains still unclear. This paper describes 6 cases of pseudolipomatosis occurring in the mucosa of stomach and large intestine, and the possible factors involved in gastrointestinal endoscopic procedure to produce gaseous entrapment in the lamina propria were analysed. All cases received either gastroscopy or colonoscpy before endoscopic biopsy. Mucosal tissues from both stomach and recto-sigmoid colon revealed multiple aggregations of small air-spaces resembling fatty infiltration in the lamina propria. Rarely were similar infiltrations within the muscularis mucosae and adjacent lymphoid follicles. Evidence for pneumatosis cystoides intestinalis or ulcerative colonic lesion was not associated, although one showed a small gastric ulcer nearby. Repeated inflations and deflations of the stomach or colon during the endoscopic procedure with miner mechanical trauma by instrument to the mucosa seem to contribute to its pathogenesis.

Percutaneous needle aspiratio biopsy of malignant lung lesions

Percutaneous needle aspiration biopsy (PNAB) of suspected pulmonary malignancy is a simple, safe and practicalmethod, so should be used earlier and moe frequently to shorten the diagnostic interval. In Korea Cancer CenterHospital, 64 patients underwent PNAB with a diagnotic yield of 87.5%. 7 patients and a pneumothorax and in 3patients developed transient hemoptysis. Of 58 malignant of no
