RESUMO
Psoriasis, vitiligo, and mycosis fungoides (MF) are among the most frequently treated dermatological diseases by photo(chemo)therapy. The objectives are to determine which photo (chemo) therapeutic modality could achieve the best response in the treatment of psoriasis, vitiligo, and MF. The design used in this study is retrospective analytical study. The study included 745 patients' records; 293 with psoriasis, 309 with vitiligo, and 143 with early MF, treated in the Phototherapy Unit, Dermatology Department, Kasr El-Aini Hospital, Cairo University by either psoralen and ultraviolet A (PUVA), narrow band ultraviolet B (NB-UVB), psoralen and narrow band UVB (P-NBUVB), broad band UVB (BB-UVB), or broad band UVA (BetaBeta-UVA). Data were retrieved from the computer database of the unit and statistically analyzed. In psoriasis, oral and topical PUVA and NB-UVB were found to be equally effective, whereas oral PUVA had significantly better results than both UVA and BB-UVB at the end of therapy. In generalized vitiligo, PUVA and P-NBUVB had significantly better results than NB-UVB alone. In early MF, there was no statistically significant difference between the response to oral PUVA and NB-UVB. PUVA and NB-UVB are good choices in patients with psoriasis and early stage MF, whereas PUVA appears the best choice in the treatment of vitiligo.
