Basaloid squamous carcinoma (BSC) is a rare variant of squamous cell carcinoma (SCC). In this study, clinicopathological and immunohistochemical characteristics of 12 superficial esophageal BSCs were examined and compared with those of typical superficial SCCs. Eight cases were classified into an elevated type, and the other four into a depressed type.(More)
OBJECTIVE To elucidate the clinical characteristics of IgG4-related retroperitoneal fibrosis (RF). METHODS IgG4-related RF was diagnosed when all of the following three criteria were fulfilled: retroperitoneal soft tissue masses surrounding the aorta and/or adjacent tissues, elevation of the serum IgG4 levels, and abundant infiltration of IgG4-positive(More)
A retrospective long-term endoscopic followup study was designed to examine atrophic changes in the gastric mucosa over time inHelicobacter pylori-positive patients. Over a period of 8–17 years (mean, 13.4 years) 22 subjects (5 men, 17 women, mean age, 55 years) without localized gastroduodenal lesions underwent serial endoscopic examinations and(More)
BACKGROUND AND STUDY AIMS Endoscopic mucosal resection (EMR) is now commonly indicated for esophageal squamous cell carcinoma (ESCC) within the lamina propria mucosa. However, EMR for ESCC that has invaded the muscularis mucosa is controversial because the risk of lymph node metastasis is not negligible. We conducted a multicenter retrospective cohort study(More)
We examined whether endocytoscopic observation of esophageal squamous cell carcinoma can replace the histologic examination of biopsy specimens. In a basic investigation, we examined 57 iodine-unstained areas in the resected specimens of the esophagus from 28 individuals. The endocytoscopic findings were graded from 0 to 3 in tandem with observations of the(More)
Patients undergoing minimally invasive esophagectomy (MIE) may benefit from lower respiratory complications and total morbidity compared with those undergoing open transthoracic esophagectomy (OTE) according to a recent meta-analysis. Local recurrence rates after MIE need to be determined for an assessment of complete resection. The aim of this study was to(More)
BACKGROUND/AIMS The objective of this study was to compare the clinical characteristics of patients with autoimmune pancreatitis (AIP) with or without Mikulicz's disease (MD) and with MD alone. METHODS We investigated the clinical findings in 15 AIP patients with MD (group A+M), 49 AIP only patients (group A), and 14 MD only patients (group M). RESULTS(More)
IgG4-related disease is a newly recognized fibroinflammatory condition characterized by tumefaction consisting of fibrosis with dense infiltration of IgG4-positive plasma cells; affecting various organs. A case of IgG4-related sclerosing mesenteritis is reported. A 64-year-old man was admitted to our hospital with a suspected tumor of the small intestine.(More)
