Living with Cutaneous nodular amyloidosis

A rare skin condition in which protein builds up in the skin, forming yellowish waxy bumps.

Understanding Cutaneous nodular amyloidosis

Cutaneous nodular amyloidosis is a rare skin disease in which abnormal protein fibers called amyloids build up in the skin.

It causes yellowish, waxy, crusted nodules and papules on the face, legs, trunk, scalp, and genitals. The primary localized form is the rarest form of primary cutaneous amyloidosis. It can be linked with connective tissue conditions such as Sjogren's syndrome and CREST syndrome.
