Self-healing juvenile cutaneous mucinosis (Q101905)

Self-healing juvenile cutaneous mucinosis is a rare disorder characterised by an early age of onset accompanied by inflammatory phenomena and spontaneous resolution over a few months. Clinically, there are papules, nodules or plaques with a predilection for the head and trunk. Histologically, there is dermal mucinosis and a mild increase in fibroblasts and mast cells. It is postulated that a temporary alteration of fibroblast synthetic function occurs, possibly as a result of a viral infection. Rare cases of self-healing cutaneous mucinosis have been reported in adults.
