Paclitaxel-induced photodermatitis is extremely rare despite the frequent use of paclitaxel-trastuzumab combination chemotherapy. A 70-year-old woman with infiltrating intraductal breast cancer developed photodermatitis after ten treatment courses of weekly paclitaxel-trastuzumab combination chemotherapy. Withdrawal of paclitaxel and sun avoidance led to its resolution. A combined effect of solar radiation and enhanced porphyrin synthesis is speculated for photodermatitis in paclitaxel. However, the issue of aberrant porphyrin biosynthesis being causal or an epiphenomenon remains unsettled as elevated porphyrins synthesis does not necessarily cause photosensitivity in all treated cases. The relevant literature on paclitaxel-induced photodermatitis and pathomechanism involved is reviewed.
