Amyloidosis comprises a diverse collection of disease characterized by the presence of amorphous extracellular eosinophilic deposits of unique protein fibrils that gives apple green birefringence under polarized light after staining with Congo red. Head and neck region is the commonest site for localized form of amyloidosis. We report a case of a 43-year-old man with localized amyloidosis of nasopharynx with oropharyngeal extension and its management, along with a review of relevant literatures.

Oncostatin M (OSM) is a cytokine with the unique ability to interact with both the OSM receptor (OSMR) and the leukemia inhibitory factor receptor (LIFR). On the other hand, OSMR interacts with IL31RA to form the interleukin-31 receptor. This intricate network of cytokines and receptors makes it difficult to understand the specific function of OSM.

Objectives: Cerebral amyloid angiopathy (CAA) is the main driver of amyloid-related imaging abnormalities (ARIAs) in Alzheimer disease (AD). We compared different versions of the Boston criteria for CAA diagnosis in AD.
Methods: This article presents a single-center analysis (outpatient neurodegenerative clinic) of patients with AD with mild cognitive impairment (MCI) or early dementia, meeting NIA-AA criteria and having biological amyloid confirmation (CSF or imaging).

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.

Importance: There is a lack of long-term efficacy and safety data on hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN) and on RNA interference (RNAi) therapeutics in general. This study presents the longest-term data to date on patisiran for hATTR-PN.
Objective: To present the long-term efficacy and safety of patisiran in adults with hATTR-PN.

Localized light chain amyloidosis is considered to be a plasmacytic B-cell lymphoproliferative disorder caused by antigenic induction. A hypothesis has been proposed that antigen-induced local plasmacytic B cells produce amyloidogenic proteins that are processed into amyloid fibrils in giant cells leading to amyloid fibril deposition. However, the inciting antigen exposure or immune response that signals plasmacytic B-cell infiltration, activation, and selection, is unknown.
