Two major types of amyloidosis are primary amyloidosis or amyloid light chain amyloidosis and secondary amyloidosis. Although amyloidosis involves a variety of organ systems including skin, the occurrence of bullous skin lesions is rare. Little is known about the mechanism of blister formation. These blisters are often hemorrhagic and typically occur in the oral mucosa. Only a few case reports ...

BACKGROUND Cutaneous amyloidosis has been classified into primary cutaneous amyloidosis (PCA, OMIM #105250), secondary cutaneous amyloidosis and systemic cutaneous amyloidosis. PCA is the deposition of amyloid in previously apparent normal skin without systemic involvement. Amyloidosis cutis dyschromica (ACD) is a rare distinct type of PCA. Here, the unique clinical and histological findings of...

Background Carpal tunnel syndrome (CTS) is one of the most common clinical manifestations of TTR-related amyloidosis, both hereditary (ATTR), and wild type (senile systemic amyloidosis, SSA) and often precedes cardiac symptoms. The exact prevalence of CTS in light-chain amyloidosis (AL), ATTR and SSA is not known. We therefore aimed to establish prevalence, risk factors and possible association...

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodula...

This study was performed in real clinical practice settings. Our paper describes two case studies which show the difficulty of differential diagnosis monoclonal gammopathies, multiple myeloma associated with AL-amyloidosis and primary AL-amyloidosis.

systemic amyloidosis and testicular interstitial tumor are rare conditions in birds and this is the first report in iran. a male zebra finch was presented because of white diarrhea, anorexia, loss of weight and lethargy. at necropsy, the small intestine was edematous and congested. the spleen appeared pale. the liver was large, firm and brown. one testis was cystic and neoplastic and the remain...

Primary cutaneous amyloidosis is limited to the skin without involving any other tissue. Nodular amyloidosis is rare, and atrophic nodular cutaneous amyloidosis is even rarer. We describe the fourth case of atrophic nodular cutaneous amyloidosis by searching PubMed databases. A 52-year-old female presented to our hospital with a 2-year history of orange papules and nodules without subjective sy...

AMYLOIDOSIS is usually categorized as a degenerative process. Nevertheless, the nature and pathogenesis of this disorder remain most uncertain. Reimann, Koucky, and Eklund (1935) have classified amyloidosis in four groups: primary, secondary, tumour-forming, and associated with multiple myeloma. Tumour-forming amyloidosis is known to occur as a primary process in the tissues of the eye, urinary...

Amyloid involvement of the tongue is almost always secondary to systemic amyloidosis. Isolated amyloidosis of the tongue is relatively rare and it accounts for less than 9% of all types of amyloidosis. We are presenting a case of a 54-year-old male patient who complained of an enlarged tongue and bilateral multiple swellings on the lateral borders of the tongue, which had been there since one y...

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)...
