Papular mucinosis, also known as lichen myxedematosus or scleromyxedema, is a chronic cutaneous disorder characterizecl by infiltration of mucin in the dermis without abnormalities of thyroid function. It often combines serum monoclonal paraproteins. Various drugs have been used for the treatment without consistent results. We report a case of papular mucinosis in a 51-year-old man, who started the disease on his scalp 10 years before the first examination. Subsequent development of the characteristic glistening papular lesions on his entire scalp, eye brows, ears and upper back continued for 5 years thereafter until complete resolution. Treatment with corticosteroids and melphalan showed only limited effects during the period. (Korean J Dermatol 1997;35(5): 984-S88)
