Dermatitis artefacta

History

          A 38-year-old married woman presented with an irregular, clear-cut, longitudinal crusted ulcer about 12×2.5 cm with pinkish red border involved the flexor aspect of the upper part of the forearm of 1 month duration. The ulcer seems to be self-induced with a caustic material (chemical burn) but the patient denied any history of self-mutilatin. The ulcer appearance plus the rapid evolution in addition to non-specific histological findings on skin biopsy may permit the diagnosis of dermatitis artefacta.
