title: A case report and discussion of cetuximab-induced folliculitis.
abstract: Use of human epidermal growth factor receptor inhibitors by oncologists has led to the occurrence of an acne-like eruption that is technically a folliculitis. Misidentification of the rash often leads to unfruitful treatment attempts as its morphologic features do not correlate well with its histologic findings. We describe a case history, diagnosis, and management of a man undergoing treatment with cetuximab for colorectal carcinoma who experienced the characteristic follicular eruption. Our patient responded well to daily moisturizers and 1% clindamycin gel and experienced near complete resolution of the rash. The evolving research and understanding of this unique entity are also discussed.
