Well-Differentiated Adenocarcinoma Spreading Widely in the Gastric Submucosa.

A 56-year-old woman was referred to our hospital due to dry mouth. Diagnostic upper gastrointestinal endoscopy showed slightly elevated lesions both on the anterior wall and lesser curvature in the upper part of the stomach. Biopsy-proven tuble-forming atypical cells in the two lesions led us to treat the presumed early gastric cancers with endoscopic submucosal dissection (ESD).

First Report of a Low-Grade Pseudomyxoma peritonei Originating from Gall Bladder.

Pseudomyxoma peritonei (PMP) refers to accumulation of mucinous ascites with or without neoplastic cells in the peritoneal cavity. It most commonly originates from a low or a high grade primary appendiceal mucinous neoplasm. Though adenocarcinoma of gall bladder has been reported to give rise to PMP, to the best of our knowledge, this is the first report of a PMP arising from a low grade mucinous tumour of the gall bladder.

A Case of Squamous Cell Carcinoma of the Breast with Low-Grade Adenosquamous Carcinoma.

A 68-year-old woman with a breast mass was referred to our hospital. Imaging studies showed an oval well-defined mass, 1.3 cm in size, in her left lower outer quadrant of the breast.

4-Amino-2-Sulfanylbenzoic Acid as a Potent Subclass B3 Metallo-β-Lactamase-Specific Inhibitor Applicable for Distinguishing Metallo-β-Lactamase Subclasses.

The number of cases of infection with carbapenem-resistant (CRE) has been increasing and has become a major clinical and public health concern. Production of metallo-β-lactamases (MBLs) is one of the principal carbapenem resistance mechanisms in CRE. Therefore, developing MBL inhibitors is a promising strategy to overcome the problems of carbapenem resistance conferred by MBLs.

Recurrence of adenoma after curative endoscopic submucosal dissection for a rectal intramucosal adenocarcinoma in adenoma.

 A 71-year-old female underwent endoscopic submucosal dissection (ESD) for a subcircumferential lateral-spreading rectal tumor. Pathological examination showed an intramucosal adenocarcinoma in villous adenoma (size: 155 × 140 mm), which had been curatively resected with negative margins. However, follow-up colonoscopy revealed a tumor at the ulcer scar site, which soon grew into a circumferential lesion.
