As with all SCARs, early recognition and prompt drug withdrawal is an essential part of the management of DRESS. In contrast to the other SCARs, however, DRESS lacks pathognomonic, or even highly suggestive, clinical morphologic characteristics. It often presents with an exanthem identical to the more common, but relatively benign, morbilliform drug reaction.1 In addition, the biopsy findings also lack signature histopathologic findings.2 To diagnose DRESS, the dermatologist must appraise the clinical scenario in its gestalt; then pursue suggestive laboratory findings, identify the common offending medications, and assess the timing of the cutaneous reaction following drug initiation. DRESS, then, is a condition vulnerable to knowledge and performance gaps.
