X-linked reticulate pigmentary disorder is a rare X-linked genetic condition in which males manifest multiple systemic symptoms and a reticulated mottled brown pigmentation of the skin, which, on biopsy, demonstrated dermal deposits of amyloid. Females usually only have linear streaks of hyperpigmentation. [1]
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.
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

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.
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.

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]
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 ...
