Self-healing juvenile cutaneous mucinosis (SJCM) is a rare primary dermal mucinosis. It presents with a sudden eruption of papules and nodules following flu-like symptoms. We hereby report a case of a 12-year-old girl, presenting with a typical eruption coupled with periorbital edema and joint nodules. SJCM diagnosis was based on a combination of clinical and characteristic histological findings. In our patient, the condition spontaneously resolved within 4 weeks and has remained asymptomatic throughout the 3-year follow-up period.
