Background. Voriconazole is a broad-spectrum antifungal agent associated with photosensitivity and accelerated photoaging. A possible link with aggressive squamous cell carcinoma (SCC) has also been reported. Objective: We sought to determine the incidence and frequency of cutaneous SCC among patients undergoing long-term treatment with voriconazole who also manifest features of chronic phototoxicity. Methods: We conducted a retrospective review of patients who developed one or more squamous cell neoplasms during long-term treatment with voriconazole at 3 academic dermatology centers. Results: A total of 51 cutaneous SCC were identified in 8 patients (median age 34.5 years, range 9-54) treated with chronic voriconazole (median duration 46.5 months, range 13-60). Underlying diagnoses included graft-versus-host disease, HIV, and Wegener granulomatosis. Signs of chronic phototoxicity and accelerated photoaging included erythema, actinic keratoses, and lentigo formation. Limitations: The retrospective nature of the study cannot determine the true population risk of SCC associated with voriconazole therapy. A prospective cohort study is needed. Conclusion: A high index of suspicion for photosensitivity and SCC may be warranted with chronic voriconazole use when used in the setting of concurrent immunosuppression.
