Lymphocytic esophagitis is a rare but increasingly recognized cause of chronic esophagitis. The pathogenesis, prognosis, and treatment are undefined. We report the diagnostic workup of an unusual cause of dysphagia. We present a case report of a 71-year-old female who presented with dysphagia for solid foods. The endoscopic appearance showed stenosis at the cricopharyngeus and trachealization of the proximal esophagus. Biopsies were taken to exclude eosinophilic esophagitis. The pathology showed lymphocytic infiltrate with peripapillary distribution with no granulocytes and spongiosis suggestive of lymphocytic esophagitis. Esomeprazol was started with symptomatic improvement. The symptoms and endoscopic appearance of lymphocytic esophagitis may be indistinguishable from other forms of chronic esophagitis. A high index of suspicion and mucosal sampling are essential to establish the diagnosis. Lymphocytic esophagitis seems to be a chronic and benign form of esophagitis. It should be included in the differential diagnosis of dysphagia. Further research and case reporting are essential to better define its pathogenesis, prognosis, and treatment.
Introduction: Acute esophageal necrosis (AEN) is a rare clinical entity, with a multifactorial etiopathogenesis and characterized by the presence of a black esophagus seen during the upper gastrointestinal (UGI) endoscopy.Case Report: A 76-year-old man with AEN was presented, whose UGI endoscopy revealed circumferential necrosis throughout the entirety of the esophageal mucosa with concomitant preservation of gastric mucosa. Conclusion:We present this case after considering the rarity of the disease and its characteristic endoscopic features, emphasizing the importance of early diagnosis and the establishment of a targeted treatment to the underlying causes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
