dermatitis artefacta, pyoderma gangrenosum,


Dermatitis artefacta is a self-inflicted skin condition that clinically mimics other dermatologic conditions. The etiology is multifactorial and is linked to underlying psychological conditions or psychosocial stressors with relief from automutilation. Lesions present with variable morphology depending on the type of self-harm and therefore, is a diagnosis of exclusion. We present a case of lesions that initially appeared to be pyoderma gangrenosum due to a similar presentation of nonspecific ulcers on the lower extremity. An important clue to the diagnose of dermatitis artefacta are skin lesions that do not fit a particular histopathological category. Lesions will also be resistant to conventional treatment. Once other dermatologic conditions are ruled out, it is important to consider dermatitis artefacta since early intervention is necessary for good patient outcomes.
