A 39-year-old male with a history of atopic dermatitis since the age of 3 years was referred because of severe hand eczema. On examination, he was found to also suffer from generalized chronic dermatitis, involving most of the body as well as the head and neck. Despite intensive topical therapy, dermatitis on the chest and, in a tubular pattern on the arms and thighs, remained hard to control, whereas hand eczema was easily controlled. The patient worked as a machinist, with skin contact with cutting fluids, metals, and gloves. Work-related contact dermatitis was suspected, and the patient was patch tested with the European baseline series, supplemented with relevant work allergens, gloves, a steroid series, and his own products. Patch testing was performed with the European baseline series [TRUE Test® panel 1–3 (SmartPractice Mekos, Hillerød, Denmark)] supplemented with the remaining allergens in Finn Chambers® on Scanpor® tape (SmartPractice, Phoenix, AZ, USA) for 48 h, and readings were performed on day (D) 3 and D7, according to published guidelines (1). The patient reacted only to p-phenylenediamine (PPD) (++), textile dye mix (++), and Disperse Blue 106 and 124 (+), the latter two only on D7.
