Self-healing juvenile cutaneous mucinosis in a patient with nephroblastoma.

Self-healing juvenile cutaneous mucinosis is characterized by an early age of onset, the presence of plaques and nodules in a characteristic distribution, and rapid onset followed by spontaneous resolution of the lesions within a period of weeks to months. Only four previous cases have been reported. The patient in this study was an 8-year-old child who developed cutaneous lesions characteristic of self-healing juvenile cutaneous mucinosis while undergoing chemotherapy for a nephroblastoma. This is the first case described of self-healing juvenile cutaneous mucinosis associated with a neoplasm.
