the UVA range, which normalized after cessation of flutamide treatment, while UVB-MED was within the normal range. Photopatch testing, performed with flutamide 10 and 20% in acetone and vaseline, showed positive results.Flutamide is a non-steroidal anti-androgen used for the hormonal treatment of prostatic cancer, while its photosensitizing capacity is well known. Reports of vitiliginous lesions as sequels of flutamide-induced photosensitive dermatitis have been rare. 1 In vitro , flutamide, the spectrum of action of which appears to be in the UVA-range, showed a photohaemolytic effect on human erythrocytes and induced lipid peroxidation. 2 Like us, other authors also found a decreased MED. 3,4 Photosensitivity to flutamide was also demonstrated by photopatch testing, although to date there seems to be no consensus regarding the nature of vehicle and the concentration of flutamide to be used. Vilaplana et al . 5 and Jiménez et al . 6 found positive photopatch tests within the UVA-and UVB-range using flutamide, as we did, dissolved at 10 and 20% in acetone. Positive photopatch tests were also determined using flutamide in petrolatum 4 and in 50% propylene glycol and 50% ethanol. 7 The development of vitiligo after application of photosensitizing drugs needs to be distinguished from contact vitiligo following exposure to depigmenting chemicals like hydroquinone or phenole. However, the pathogenetic mechanisms are not yet clearly understood. Although there are reports of vitiligo-like lesions following systemic treatment like PUVA therapy 8,9 or promethazine, 10 to date only two reports of residual vitiligo following approximately 2 months of photosensitive reactions to flutamide have been published. Meanwhile, in the case reported by Vilaplana et al ., 5 vitiliginous lesions decreased by about 50% within 9 months under systemic treatment with a hydrophilic extract of polypodium leucotomos and topical application of phenylalanine 10% gel and corticosteroids. Jiménez et al . 6 described a slow but progressive, and in some parts almost complete repigmentation within 8 months of treatment with polypodium leucotomos and narrow-band UVB phototherapy in another case of widespread vitiligo following flutamide-induced exfoliative dermatitis.
EditorA 25-year-old woman, infected with human immunodeficiency virus (HIV) since 1994 and with a past history of pulmonary tuberculosis, pneumocystosis, cytomegalovirus (CMV) retinitis, ' in situ ' carcinoma of the cervix, and pelvic inflammatory disease, presented with a 2-month history of a widespread itchy eruption all over the skin. She had been treated previously with topical monosulphiram, menthol lotions, and 1% lindane, without any relief of symptoms. In recent months she had had systemic courses of cotrimoxazole and prednisone for Pneumocystis carinii , gancyclovir for CMV infection, and a combination of azydothimidine, indinavir, stavudine and lamivudine for HIV infection.Viral load and CD4 count were not available from her records.
