Living with Localized lichen myxedematosus

A rare skin condition with small, firm, waxy bumps in a few areas of the body.

Understanding Localized lichen myxedematosus

Localized lichen myxedematosus is a rare skin disorder in which a substance called mucin builds up in the skin.

It causes small, firm, waxy bumps (papules) in only a few places on the body. It is the localized, less severe form, also called papular mucinosis. People are typically otherwise healthy. GARD notes it typically does not require therapy.
