Waltzer and Flowers1 have identified a chemotherapy-induced bullous variant of acral erythema that is always associated with cytarabine, given alone or in combination with other agents. We report a case of bullous acral erythema occurring after the administration of high-dose methotrexate to an adolescent patient.
Report of a Case.
A 13-year-old girl was treated with methotrexate for chondroblastic osteogenic sarcoma of the left humerus at a dose of 12 g/m2 (14 g per cycle). Each cycle was given at 1-week intervals. Within 24 hours following the seventh cycle, a symmetrical, edematous, painful, red, violaceous erythema developed on the balls of the feet and the fleshy part of the toes.

Simultaneously, diffuse macular lesions, which were purpuric and necrotic
