Abstract

We present four clinicopathological correlated cases of young patients with cryothermic dermatitis artefacta. They were initially misdiagnosed as primary bullous dermatoses or fixed drug eruptions. Cryothermic dermatitis artefacta can imitate authentic dermatoses such as linear IgA bullous dermatosis, herpes virus infection, bullous pemphigoid or fixed drug eruption. It should be considered as differential diagnosis in uncommon cases of recurrent bullae in adolescent and young adult patients. We summarize helpful clinical and histopathological criteria for correct diagnosis and therewith causative treatment.

Keywords: Bullous skin diseases; Factitious dermatitis; Fixed drug eruption; Herpes simplex virus infection; Psychodermatology.
