Papular mucinosis associated with acquired immunodeficiency syndrome.

Papular mucinosis, also known as lichen myxedematosus, is a rare, idiopathic disorder in which focal deposits of mucin accumulate in the dermis. It has been previously reported in two patients with human immunodeficiency virus infection; we describe a third such case and note the presence of a granuloma adjacent to the mucin deposit. We also comment on other clinical manifestations of cutaneous mucin deposition and granuloma formation in human immunodeficiency virus infection.
