Bevacizumab-Induced Cutaneous Lupus Erythematosus in a Patient With Metastatic Colon Carcinoma: A Case Report.

Bevacizumab, an anti-vascular epidermal growth factor inhibitor, is approved for the treatment of various cancers. Hypertension, gastrointestinal perforation, bleeding manifestations, impaired wound healing, and cerebrovascular accidents are common side effects associated with the monoclonal antibody. Uncommon cutaneous reactions like exfoliative dermatitis associated with bevacizumab have been documented in the medical literature. We present an unusual case of bevacizumab-induced cutaneous lupus in a patient with metastatic colon cancer that started resolving after discontinuing chemotherapy. Timely intervention was key in preventing the progression of this chemotherapy-induced cutaneous lupus.
