Bezoars are a rare cause of intestinal obstruction, but morbidity and mortality of late diagnosis and complication are high. Generally, bezoars remain in the region of the stomach; however, infrequently, they will pass to the small bowel. The clinical diagnosis of bezoar is challenging, and initial radiographs are frequently nondiagnostic. Early recognition of this entity on plain film or by computed tomography is important to prevent late complications. In addition, bezoar formation can indicate underlying psychiatric disorder that requires evaluation and therapy. We present a child with classic radiographic trichobezoar that had passed to the distal ileum and resulted in subsequent perforation.
Mantle cell lymphomas are uncommon subtypes of non-Hodgkin's lymphoma with poor overall survival ranging from 3-5 years. Patients are often middle aged men who would present with generalized lymphadenopathy and typical constitutional symptoms. Extranodal disease is typically found in the gastrointestinal tract, liver, spleen, and central nervous system. Lung involvement is typically restricted to parenchymal lesions. Endotracheal involvement is quite uncommon with less than 5% of cases. We present an unusual case of treated mantle cell lymphoma recurring 7 years later with only endotracheal involvement demonstrated by fluorodeoxyglucose-positron emission tomography.
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.
