RESUMO
La micosis fungoide es un linfoma cutáneo de células T de etiología desconocida que afecta principalmente a la población adulta. En sus fases iniciales la fototerapia sigue siendo una de las principales opciones terapéuticas. La terapia con NB-UVB en estadios tempranos IA-IB en parches y placas delgadas ofrece ventajas sobre el PUVA, debido a su mejor tolerancia y menores efectos secundarios; la terapia PUVA sigue siendo la elección en micosis fungoide en placas de mayor grosor. En cuanto a la terapia de mantenimiento se plantea que podría estar asociada a mayor radiación acumulada, sin lograr prevenir futuras lesiones, siendo el antecedente de recaída el principal factor predisponente para presentar nuevas lesiones en el futuro.
Mycosis fungoides (MF) is a cutaneous T-cell lymphoma of unknown etiology that primarily affects the adult population. In early stages of the disease phototherapy is a major therapeutic option. At the time NB-UVB therapy in early stages IA-IB patchy and thin plaques offers advantages over PUVA, due to its better tolerance and fewer side effects, the PUVA therapy remains the choice to MF in thinner plaques. The maintenance therapy is posed that could be associated with higher accumulation of radiation without achieving prevents future lesions, being the history of relapse the main predisposing factor to present new lesions in the future.
RESUMO
A 67-year-old man presented with several nodules on the extremities followed by mycosis fungoides of 5 years' duration. On biopsy of the newly formed nodule, Ki-1 positive large cell lymphoma was diagnosed. He was treated with methotrexate, topical and intralesional steroids and PUVA for as long as 7 years. We herein report the follow-up course and efficacy of the therapeutic modalities.
