Primary cutaneous amyloidosis is a form of amyloidosis associated with oncostatin M receptor. [ 2 ] [ 3 ] This type of amyloidosis has been divided into the following types: [ 4 ] : 520 Macular amyloidosis is a cutaneous condition characterized by itchy, brown, rippled macules usually located on the interscapular region of the back.
Amyloidosis is a group of diseases in which abnormal proteins, known as amyloid fibrils, build up in tissue. [4] There are several non-specific and vague signs and symptoms associated with amyloidosis. [5] These include fatigue, peripheral edema, weight loss, shortness of breath, palpitations, and feeling faint with standing. [5]
To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR). [3]
X-linked reticulate pigmentary disorder (familial cutaneous amyloidosis, Partington amyloidosis, Partington cutaneous amyloidosis, Partington syndrome type II, reticulate pigmentary disorder, X-linked reticulate pigmentary disorder with systemic manifestations) Yemenite deaf-blind hypopigmentation syndrome
AL amyloidosis is caused by the deposition of abnormal antibody free light chains. The abnormal light chains are produced by monoclonal plasma cells, and, although AL amyloidosis can occur without diagnosis of another disorder, it is often associated with other plasma cell disorders, such as multiple myeloma and Waldenström's macroglobulinemia. [6]
AA amyloidosis is a form of amyloidosis, a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest ...
Lattice corneal dystrophy type II. Black and white light micrograph showing deposits of amyloid in cornea. Congo red stain. Diagram depicting gelsolin and the amyloid protein derived from it because of mutations in codon. Lattice corneal dystrophy has three types: [3] type I: with no systemic association.
Red free photography is also regularly used as a base line photo prior to Angiography. [13] Angiography is a process of photographing/recording vascular flow within the retina and surrounding tissue by injecting a fluorescent dye into the blood stream. This dye fluoresces a different colour when light from a specific wavelength (excitation ...
