A 50-year-old Caucasian male experienced severe vesicular dermatitis of the hands, arms, face, chest and genitals several hours after using pao ferro to build a guitar (Fig. 1). There were no respiratory symptoms. Topical treatment was insufficient to clear the eruption, and a course of oral methylprednisolone was needed. The patient was participating in a guitar-building workshop, and had been exposed to pao ferro on two previous occasions, without any skin complaints. He also worked with glues and other woods (maple, walnut, spruce, and ebony), which caused him no problems. The patient has played the guitar himself since childhood, and had never experienced any complaints previously. Patch tests were performed with the Belgian baseline series and different woods provided by the patient: East Indian rosewood, African blackwood, Bubinga, black walnut, Honduras rosewood, African ebony, Honduras mahogany, Amazon rosewood, and santos rosewood (pao ferro). Scrapings of the woods as such were tested at 10% pet. The patch tests were placed on the upper back, and occluded for 2 days with Van der Bend chambers® (Van der Bend, Brielle, The Netherlands) fixed with Hypafix® (BSN Medical, Hamburg, Germany).
