Treatment depends on the type of amyloidosis that is present. Treatment with high dose melphalan, a chemotherapy agent, followed by stem cell transplantation has shown promise in early studies and is recommended for stage I and II AL amyloidosis. [26] However, only 20–25% of people are eligible for stem cell transplant.
Macular amyloidosis is a cutaneous condition characterized by itchy, brown, rippled macules usually located on the interscapular region of the back. [ 4 ] : 521 Combined cases of lichen and macular amyloidosis are termed biphasic amyloidosis, and provide support to the theory that these two variants of amyloidosis exist on the same disease ...
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.

The disorder is primarily associated with eye, skin, and cranial nerve symptoms with the onset of symptoms appearing between the thirties and fifties. [3] The most common characteristic is type II lattice corneal dystrophy with other signs such as polyneuropathy, dermatochalasis, open-angle glaucoma, bilateral progressive facial paralysis, cutis laxa, skin fragility with ecchymosis, facial ...
The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3] Within the latter type, the hairs occur in structures called pilosebaceous units , each with hair follicle , sebaceous gland , and associated arrector pili muscle. [ 4 ]
In August 2018, the FDA approved patisiran, an siRNA-based treatment, at an expected cost of up to $450,000 per year. [16] In August 2021 six patients with hereditary ATTR amyloidosis with polyneuropathy were given doses of NTLA-2001, based on a CRISPR gene editing system. Researchers reported mild adverse events and decreases in serum ...
Amyloid purpura is a condition marked by bleeding under the skin in some individuals with amyloidosis. [1] Its cause is unknown, but coagulation defects caused by amyloid are thought to contribute. Presentation
Secondary cutaneous amyloidosis is a skin condition that occurs following PUVA therapy and in benign and malignant cutaneous neoplasms in which deposits of amyloid may be found. [ 1 ] : 522 [ 2 ]
