Amyloidosis is characterized by extracellular deposition of abnormal protein, consisting of primary, secondary, hemodialysis-related, hereditary, senile and localized type. Primary amyloidosis is associated with monoclonal light chains. Secondary amyloidosis is associated with inflammatory, infectious, and neoplastic diseases. Amyloid deposition in the gastrointestinal tract can manifest the sy...

Seminal vesicle (SV) amyloidosis is a well-documented histological entity, but it is observed infrequently. Its incidence is on the rise, which is probably related to the increasing use of prostate biopsies to investigate patients with elevated serum prostate-specific antigen levels. Here, we report seven cases of incidental SV amyloidosis over a 3-year period and consider their relationship to...

AMYLOIDOSIS is a disease characterized by deposition of amyloid proteins in various body tissues. The natural history of primary amyloidosis is poorly understood, and the clinical diagnosis is often not made until the disease is far advanced. There is a high prevalence of conduction disturbances associated with this disease, and heart-related problems are a frequent cause of death for patients ...

Amyloidosis is a rare, mysterious and serious disorder. The extracellular deposition of seemingly homogenous and amorphous material actually represents the expression of very diverse pathologies. All amyloid fibrils share apple green birefringence under polarized light with Congo-red staining, and are arranged in beta-pleated structure on electron microscopy. More than 21 proteins have been ide...

Amyloidosis is a syndrome characterized by deposition of a highly insoluble protein material in the extracellular space that may affect several organs. It may be generalized and idiopathic (primary amyloidosis). We describe the case of a 48 years-old woman with axonal neuropathy associated with proteinuria, whose final investigation resulted in diagnosis of primary amyloidosis (AL). She was sub...

Pulmonary amyloidosis is a rare disease, characterized by extracellular deposition of fibrillary protein in the lungs. Primary pulmonary amyloidosis is rare disease, that present focal or systemic characteristics. The secondary system form is generally related to neoplastic, infectious, or chronic inflammatory processes, chronic kidney disease, syphilis, leprosy, inflammatory bowel disease, ost...

Embolic cerebral infarction due to cardiac amyloidosis is rare. We report two patients with amyloidosis who developed cerebral infarcts. These embolic infarcts were probably related to cardiac involvement of amyloidosis, which was based on results of myocardial biopsy (Patient 1), and kidney biopsy and characteristic echocardiographic features including granular sparkling, restrictive cardiomyo...

Leukocyte cell-derived chemotaxin 2 (LECT2)-related amyloidosis (ALECT2) constitutes a subtype of systemic amyloidosis affecting the kidney. This is the first case describing mixed ALECT2 and Amyloid A renal amyloidosis in a Kazakh-German patient. Genetic analysis shows a polymorphism in the LECT2 gene and a homozygous mutation in the SAA1 gene. Notably, our patient has a body mass index of 61 ...

We hereby report a 79-year-old Iranian man presenting with nail dystrophy and subsequent development of purpuric and ecchymotic plaques, hemorrhagic bullae, and infiltrated papules on the head, neck and trunk. Histological examination of the gingiva, bone marrow aspiration, and biopsy confirmed the diagnosis of primary systemic amyloidosis. In this case, nail dystrophy was the presenting sign o...
