Metachronous Multiple Clinical Presentations Involving the Skin in a Patient with Immunoglobulin G4–Related Sclerosing Disease

Abstract

years after resection without recognition of IgG4-RD. As the primary skin lesion prior to the systemic symptoms was rare and mostly appeared in head and neck (Charrow et al ., 2016). Once again at this recurrence, cutaneous dermatofibroma wasn’t initially identified as the primary symptom of IgG4 -RD. Therefore, IgG4-RD should be fully considered and evaluated in clinical practices to avoid unnecessary and potentially harmful operations.
