Psoriasis, Amyloidosis - cutaneous conditions - Wikipedia

Psoriasis - cutaneous conditions - Wikipedia

Psoriasis is a common, chronic, and recurrent inflammatory disease of the skin characterized by circumscribed, erythematous, dry, scaling plaques.[94][95][96]

Amyloidosis

n medicine, amyloidosis refers to a variety of conditions wherein normally soluble proteins become insoluble and are deposited in the extracellular space of various organs or tissues, disrupting normal function.[1] The insoluble fibrous protein aggregates that develop in amyloidosis are known as amyloids. They result from a change in the protein's secondary structure, which causes the protein to take on a particular aggregated insoluble form, similar to the beta-pleated sheet.[2] Symptoms vary widely depending upon where in the body amyloid deposits accumulate. Amyloidosis may be inherited or acquired.[3] Senile systemic amyloidosis was determined to be the primary cause of death for 70% of supercentenarians who have been autopsied.[4][5]
