RATIONALE Nasopharyngeal amyloidosis is a benign, slowly progressive disease that is characterized by extracellular eosinophilic deposition. PATIENT CONCERNS We report a rare case of localized nasopharyngeal amyloidosis. DIAGNOSES The initial chief complaint of this patient was frequent epistaxis and right aural fullness. The initial diagnosis was nasopharyngeal tumor. INTERVENTIONS There...

Although AL amyloidosis usually is a systemic disease, strictly localized AL deposits are not exceptionally rare. Such case reports form a considerable body of published articles. Although both AL amyloidosis types are formed from an N-terminal segment of a monoclonal immunoglobulin light chain, a typical localized AL amyloid differs from the systemic counterpart by the morphological appearance...

INTRODUCTION The larynx is a rare site of deposition for amyloidosis. Diagnosis may be delayed and evoked in patients with prolonged hoarseness. We have reported two cases of laryngeal amyloidosis. EXEGESIS One man and one woman suffered from hoarseness during one and three years, respectively. Laryngoscopic examination showed diffuse infiltration of the larynx. Amyloidosis was confirmed by t...

Amyloidosis is a heterogeneous group of diseases with a common outcome: deposition of insoluble protein in the visceral organs and tissues. Primary amyloidosis is a consequence of different plasma cell disorders, and it is the most common form of amyloidosis in the United States with an estimated 2,000 new cases annually. Other forms of amyloidosis include chronic inflammatory processes, famili...

Amyloidosis is characterized by the abnormal deposition of extracellular amyloid fibrils. Cases involving amyloid light-chain amyloidosis in the small intestine have been reported infrequently in Korea. Here, we report a case of localized light chain protein amyloidosis in the small intestine. Esophagogastroduodenoscopy, push enteroscopy, and capsule endoscopy revealed submucosal tumor-like les...
