Respiratory amyloidosis is a rare disease which refers to localized aberrant extracellular protein deposits within the airways. Tracheobronchial amyloidosis (TBA) refers to the deposition of localized amyloid deposits within the upper airways. Treatments have historically focused on bronchoscopic techniques including debridement, laser ablation, balloon dilation, and stent placement. We present...

INTRODUCTION Amyloidosis is characterized by extracellular deposition of abnormal insoluble fibrils, which cause structural and functional disorders. Amyloidosis is classified into primary and secondary disease. We report a case of localized amyloidosis of the urinary bladder. In the English literature, this is the first case effectively treated with occlusive dressing therapy using dimethyl su...

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma. We present a 49-year-old woman with a chief complaint of flank pain. A filling defec...

BACKGROUND Primary localized cutaneous amyloidosis (PCA) is a relatively rare condition characterized by amyloid deposition in dermis without systemic involvement. Although, histopathological examination of the lesion reveals amorphous eosinophilic deposits in papillary dermis examination of congo red stained slides under polarized light will give definitive diagnosis AIMS To study the clinic...

Amyloidosis has been classified by Symmers (1956) into (1) generalized secondary amyloidosis; (2) generalized primary amyloidosis ; and (3) localized amyloidosis. Involvement of the respiratory tract by amyloid material in the generalized systemic form of the disorder is not as rare as is commonly supposed. In amyloidosis associated with a recognized predisposing disease the incidence is at lea...

Amyloidosis is a benign, slowly progressive condition characterized by the presence of extracellular fibrillar proteins in a variety of organs and tissues. It can be categorized as systemic or localized. Head and neck involvement can be seen in both systemic and localized amyloidosis. Systemic amyloidosis results in involvement of many organs, and shortens life expectancy, whereas localized amy...

Amyloidosis is a disorder of protein metabolism characterized by extracellular deposition of abnormal protein fibrils. It may either be localized to any organ or systematically distributed throughout the body. The biochemical nature of proteins varies but the physical and tinctorial properties are shared by all the amyloidogenic proteins. In the West, it is mainly composed of amyloid light (AL)...
