BACKGROUND: Dermatitis artefacta (DA) is difficult to diagnose by clinical findings alone. Histopathologic analysis may rule out organic disorders and in some cases establish, in conjunction with microanalytic techniques, a definite diagnosis. OBJECTIVE: We report a young woman with DA in the form of recurrent abscesses whose diagnosis was aided by the identification of subcutaneous foreign material through histologic and microanalytic methods. METHODS: Histologic examination showed foreign body giant cell reaction with polarizable material, which was identified as cellulose by energy dispersive x-ray analysis and Fourier transform infrared spectrometry. RESULTS: Self-injection of exogenous matter was suspected. Referral to an expert in psychodermatology resulted in the diagnosis of multiple psychiatric comorbidities commonly associated with DA. Initiation of antidepressants resulted in marked improvement in her skin disease, as well as her mood and affect. CONCLUSION: We emphasize the importance of interdisciplinary collaboration between dermatologists, dermatopathologists, and mental health professionals in the management of DA.
