Congenital cutaneous mucinosis with spontaneous regression: An atypical cutaneous mucinosis of infancy?

Abstract

The nomenclature and classification of cutaneous mucinosis is quite complex. An updated classification of idiopathic cutaneous mucinosis (lichen myxoedematosus), included three clinicopathological subsets: a generalized papular and sclerodermoid form, a localized papular form, and an atypical or intermediate form. Cutaneous mucinosis occurring in infancy is very rare. We report a 7-month-old boy with a history of multiple opalescent papules over his fingers and toes since birth. The lesions spontaneously regressed and became indiscernible after 5 years of clinical follow-up. The condition was similar to cutaneous mucinosis of infancy but was also unique because of its spontaneous regression and acral location. ? 2008 British Association of Dermatologists.
