A case of primary oral mucosal diffuse large B-cell lymphoma(DLBCL)due to long-term use of methotrexate(MTX)for the treatment of rheumatoid arthritis(RA)was admitted to the Department of Hematology,Fujian Medical University Union Hospital.We analyzed and discussed the clinical features,diagnosis and treatment,and prognosis of specific malignant lymphoma induced by MTX in this RA patient.Our purpose is to improve the awareness and knowledge of other iatrogenic immunodeficiency-associated lymphoproliferative disorders of clinicians and pathologists.This study provides a new reference for the clinical diagnosis and treatment of MTX-associated DLBCL.

The versatile properties of carbohydrate polymers make them a relevant, promising precursor to design innovative materials for use in biomedical applications. Recent research mainly focuses on the development of the polysaccharide based functional materials. Hydrogel derived materials are a source of great motivation for the development of drug delivery (DD) carriers with inherent therapeutic potential.

In this case report, we present a 63-year-old man with a history of diabetes mellitus and kidney transplantation who was diagnosed with nasal myiasis. The patient presented with symptoms of nasal myiasis infestation, including epistaxis, nasal obstruction, nasal discharge, and the presence of larvae. The patient had risk factors for poor wound healing, such as hyperglycemia, and the presence of diabetes mellitus, hypertension, and kidney transplantation indicated the presence of predisposing factors for myiasis.

Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.

Rationale: Biliary intraepithelial neoplasm (BilIN) is characterized by a microscopically identifiable preinvasive neoplasm of the biliary tract. BilIN is rarely diagnosed intentionally and is often detected incidentally in surgical specimens obtained via surgical resection for other types of cancers. Herein, we report a rare case of high-grade BilIN localized in the distal bile duct.

Phlegmonous gastritis is a rare, suppurative bacterial infection of the gastric wall and one of the rarest complications after upper gastrointestinal endoscopy. The pathogenesis is not fully clear, but multiple risk factors have been described in literature as mucosal injury and achlorhydria. We report a case of a 76-year-old male with vomiting and epigastric pain, two days after an upper endoscopy, who presented in septic shock.
