A case is reported of apparent podophyllum toxicity. The patient was a 17-year-old female Indian who had received some 3 to 8 cc of a 20 percent mixture of podophyllum resin in compound tincture of benzoin (approximately equal to 0.4 gm of podophylotoxin) as an application to her vulvar condylomata. She returned to the hospital 20 hours after application in a comatose state. On examination she demonstrated severe toxicity including bone marrow, liver, and central nervous system. She required a charcoal hemoperfusion at the University of Colorado, and six months after the event has several neurologic and physiologic sequelae. Podophyllum is a potentially severely toxic drug. Great care must be taken when treating patients with this drug. A large mass of condylomata or the status of pregnancy should be relative contraindications to the use of podophyllum.
