Human papilloma virus (HPV) has been suggested as an etiology of esophageal squamous cell carcinoma (SCC). The aim of this study was to investigate the prevalence of HPV infection in esophageal SCCs in our region with strict contamination control to prevent false positive results. Thirty cases of esophageal squamous cell carcinomas were chosen by simple random selection in a period of two years. PCR for target sequence of HPV L1 gene was performed on nucleic acid extracted from samples by means of GP5+/GP6+ primers. All tissue samples in both case and control groups were negative for HPV-DNA. Although the number of cases in this study was limited, the contribution of HPV in substantial number of esophageal SCCs in our region is unlikely.

is a topoisomerase I inhibitor used for the treatment of various cancers, such as gastrointestinal, pancreatic, pulmonary, ovarian, and cervical cancers. Among chemotherapy agents, it represents a rare trigger of drug hypersensitivity reactions, with few cases being reported until today. We present the case of a patient with metastatic esophageal cancer and a history of -induced grade IV (WAO classification) anaphylaxis.

Background/objectives: Superficial esophageal cancer is diagnosed by evaluating the vascular architecture, including dilation, tortuosity, caliber change, and shape, of a lesion. However, this diagnosis is subjective and requires extensive experience. Endoscopically distinguishing squamous intraepithelial neoplasia (SIN) from esophageal cancer is difficult.

In homeostatic conditions, the basal progenitor cells of the esophagus differentiate into a stratified squamous epithelium. However, in the setting of acid exposure or inflammation, there is a marked failure of basal cell differentiation, leading to basal cell hyperplasia. We have previously shown that lysyl oxidase (LOX), a collagen crosslinking enzyme, is upregulated in the setting of allergic inflammation of the esophagus; however, its role beyond collagen crosslinking is unknown.
