Radiation recall dermatitis (RRD) is a rare and poorly understood phenomenon, constituting an inflammatory skin reaction to a previously irradiated area of skin following the administration of certain agents, usually chemotherapy. Our patient developed RRD 66 years after receiving radiation therapy; to the best of our knowledge, this is the longest reported period in the literature. The mainstay of therapy is to withhold the agent that elicited the adverse reaction, followed by symptomatic management. Subjecting patients to further chemotherapy can provoke another episode of RRD. Therefore, clinical judgment in this regard is usually recommended.
