Periorbital edema and phototoxic rash associated with dasatinib: A case report.

Dasatinib is an effective agent in the treatment of bcr-abl positive acute lymphoblastic leukemia and chronic myeloid leukemia cases. Various skin reactions may occur when tyrosine kinase inhibitors are used. The severity of side effects increases in phototoxic reactions with sunlight. In this case, a phototoxic rash that developed in a 78-year-old bcr-abl positive acute lymphoblastic leukemia patient is presented. This case supports that phototoxic reactions may occur with dasatinib and emphasizes that clinicians should be alert for this side effect.
