Self-Healing Juvenile Cutaneous Mucinosis: A Report of Two Cases With Differing Evolution.
The American Journal of dermatopathology(2023)
摘要
ABSTRACT:Self-healing juvenile cutaneous mucinosis is a rare entity, characterized by the presence of subcutaneous nodules together with frequent nonspecific systemic symptoms, which occurs in the pediatric age and characteristically resolves spontaneously. Although the diagnostic criteria do not require a biopsy to be performed, it is frequently performed, and an abundant dermal mucin deposition will be observed together with other features such as fibroblastic proliferation. Although the prognosis is benign, follow-up is required for the eventual development of a rheumatologic disease.We present 2 clinical cases, describing the clinical findings and their histopathologic correlation. Comparatively, the outcome in both cases was different: in one case, the mucinosis resolved without any related event in the follow-up, and in the other case, the resolution was accompanied by the subsequent development of idiopathic juvenile arthritis.
