Localized (primary) pulmonary amyloidosis associated with pulmonary low-grade B cell lymphoma is rarely occurred. Here we report an unusual case of nodular pulmonary amyloidosis and obvious ossification due to primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma with extensive plasmacytic differentiation in a 59-year-old man; moreover, two bronchial lymph nodes were involved hist...

INTRODUCTION Amyloidosis most often manifests as a systemic involvement of multiple tissues and organs, and an amyloidal deposit confined to the stomach is extremely rare. It is sometimes difficult to provide a definitive diagnosis of localized gastric amyloidosis by biopsy specimen and diagnosis of amyloidosis in some cases has been finalized only after surgical resection of the stomach. CAS...

Amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different tissues and organs, where it usually causes some type of dysfunction. Its cause is unknown. The two main forms of amyloidosis are systemic and localized; the latter is rare. No satisfactory treatment for systemic amyloidosis has been discovered, and mean survival is poor, ranging from 5 to 15 months dep...

Not all forms of amyloidosis are systemic. Some patients may present with a localized form and should not be treated with chemotherapy. Some patients with systemic amyloidosis may have secondary, familial, or dialysis-related types.These types are not responsive to chemotherapy. Immunoglobulin light chain (primary or AL) amyloidosis is a plasma cell dyscrasia. Suppression of light chain product...

Immunoglobulin-derived light chain amyloidosis can occasionally be associated with localized disease. We present a patient with localized lymph node light chain amyloidosis without an underlying monoclonal protein or lymphoproliferative disorder and review the literature of lymph node amyloidosis discussing work-up and risk factors for systemic progression.

Localized laryngeal amyloidosis is a rare disease with poorly understood aetiology. The commonest symptom at presentation is dysphonia and for a correct diagnosis of amyloidosis to be made a high index of suspicion is needed [Fraihat A, Ardah A. Laryngeal amyloidosis: a case report. J R Med Serv 2005;17:57-9; Passerotti GH, Caniello M, Hachiya A, Santoro PP, Imamura R, Tsuji DH. Multiple sited ...
