Importance: Self-healing juvenile cutaneous mucinosis is a very rare, self-limiting disease characterized by the abrupt onset of asymptomatic papules and nodules located primarily on the face and periarticular regions of a juvenile patient. There have been less than 20 cases reported since it was first described in 1973. Observations: Most cases have been reported in children 15 years and younger. Herein we present a case affecting a 17-year-old. To our knowledge, this the oldest reported patient with this condition in the USA. Conclusions and Relevance: Despite the rarity of this disease, it is important to keep SHJCM on the differential in pediatric patients presenting with proliferating papules and nodules. Knowledge of this entity may prevent unnecessary diagnostic testing and aggressive treatment in the pediatric population with this self-limited disease.
