Abstract
Dermatitis artefacta is a self-inflicted cutaneous disease presenting as sharply delineated ulcers, usually in accessible sites such as the head and neck. IgG4-related disease (IgG4-RD) is a recently recognised immune-mediated condition causing a fibroinflammatory process, resulting in the formation of tumefactive lesions in various organs, rarely presenting primarily in the skin. We report a case of cutaneous IgG4-RD clinically presenting as dermatitis artefacta.
