An unusual case of transient papular mucinosis associated with carpal tunnel syndrome

A 67-year-old man presented with discrete mucinous papules on the scalp and fingers, and bilateral carpal tunnel syndrome. Both features remitted spontaneously within several months. The acral distribution, and histopathological features, were in keeping with the recently described acral persistent papular mucinosis. Involvement of the scalp, however, has not previously been described, and transient mucin deposition is unusual. The history of bilateral carpal tunnel compression raises the possibility of extracutaneous involvement, not previously reported in this group of patients.
