Painful nipple hyperkeratosis secondary to vemurafenib

Abstract

Vemurafenib is a selected BRAF kinase inhibitor approved for treating metastatic or unresectable melanoma, which has numerous cutaneous side effects unfortunately, including three previously reported cases of asymptomatic areola and/or nipple hyperkeratosis. We present the first case of painful bilateral nipple hyperkeratosis secondary to vemurafenib in an 84-year-old woman. She was successfully treated with tretinoin 0.05% cream that allowed her to comfortably continue treatment. With increased awareness of this condition, we found a second case of asymptomatic nipple hyperkeratosis secondary to vemurafenib in our clinic. As this medication gains acceptance for treatment of metastatic melanoma, it is imperative that dermatologists are aware of this potentially uncomfortable side effect that can result in decreased compliance and impaired quality of life.
