Long-Term Medical Follow-Up (for More than 15 Years) of a Patient with Stage IA Mycosis Fungoides Originally Presenting in Childhood: Remission for >15 Years with Localised Electron Beam Therapy.

A man now aged 80 years has received specialist care for stage 1A mycosis fungoides for 58 years. The disease developed in childhood. Long-term follow-up (>30 years) of patients with mycosis fungoides is infrequently described in the world literature. The disease in this patient was limited to 5 areas, but these were large (up to 25 cm in diameter). The rest of the skin was normal clinically. All 5 areas were treated separately with electron beam therapy (3-4 MeV) to a dose of 30 Gy in 15 fractions over 3 weeks between 2000 and 2005. Complete regression was obtained in all 5 areas, and the patient has been in complete remission for 15 years after living with the disease previously for over 40 years.
