Papular Mucinosis. Presented by Dr. Adolph Rostenberg, Jr., Dr. Harold Shellow, and (by invitation) Dr. Diana Bogdonoff.
The patient is a 54-year-old white man. Twenty-five years ago he noted 3 areas of hair loss on his head, which were unaffected by sun or topical medications. About 6 weeks ago he suddenly noticed the skin lesions on his face, anterior upper chest, shoulders, upper arms, and outer forearms. These were mildly pruritic in nature and unaffected by medication.
Biopsy specimens were taken from the lesions of the scalp, the outer arms, and the chest. The biopsy specimens from the arms and chest show considerable deposits of mucin. The sections from the scalp show merely a nonspecific dermatitis, and, while some mucin was present, it was not believed to be more than would normally be found.
Dr. Allan L. Lorincz: I believe that the term "papular mucinosis" has been applied
