Amyloidosis is a disease characterized by the deposition of altered proteins in tissues. Amyloid deposition always occurs in the extracellular matrix and presents a fibrillary conformation. Local deposition of amyloid may occur in individual organs, without systemic involvement. We report here a rare case of localized penile shaft amyloidosis--an unusual location for amyloid deposition--present...

Primary localized cutaneous amyloidosis is a skin-limited amyloidosis that does not involve internal organs. It is clinically subclassified into 3 general categories and some rare variants. However, there is considerable overlap within the classification. Though there are a variety of therapeutic measures, the treatment is often unsatisfactory, particularly when the disease is severe and extens...

Polarisation microscopy of material obtained by fine needle biopsy of subcutaneous tissue and stained with Congo red is a simple and reliable method for the diagnosis of systemic amyloidosis. It cannot, however, be used to differentiate histologically between different forms of amyloidosis. In the present study extracts of material obtained by fine needle biopsy of subcutaneous fat tissue from ...

INTRODUCTION Amyloid A (AA) amyloidosis is a systemic form of amyloidosis secondary to chronic infections and inflammatory disorders. An acute-phase protein produced by the liver, serum amyloid A (SAA) is the precursor of AA amyloid fibrils. AA amyloid deposition occurs predominantly in the kidneys, spleen, adrenal glands, liver and gastrointestinal tract. The manifestations of AA amyloidosis i...

For several years, there has been a significant increase in the number of patients diagnosed with cardiac amyloidosis. However, are still difficulties associated diagnosis, identifying its type and further treatment disease. The diversity clinical symptoms, absence pathognomonic symptoms make it difficult to diagnose, which leads progression Heart involvement is main cause morbidity mortality s...

Amyloidosis is typically a systemic depositional disease, diagnosed on clinical symptoms and signs in conjunction with histopathology. When occurring on a localized basis in the head and neck, the lesion is most commonly observed in the larynx. Primary localized nasal amyloidosis however is an uncommon finding, with 25 reported cases in the literature to date. We present the case of a young wom...

Amyloidosis is the extracellular fibril deposition of a variety of proteins, many of which circulate as plasma ingredients. It is a disease difficult to identify due to its nonspecific symptoms and manifestations. Amyloidosis of the tongue, either isolated or part of the systemic disease, is rare and its features resemble those of a tumor. We report the case of a patient with amyloidosis who pr...

Urethral amyloidosis is a rare condition that can cause hematuria and urinary obstruction symptoms. While there is no established association between immunoglobulin A (IgA) nephropathy and secondary amyloidosis, which is typically found in chronic inflammatory conditions, it is hypothesized that IgA nephropathy may be a systemic condition with inflammatory mediators. We present a case of urethr...
