  • For maintenance treatment with topical calcineurin inhibitor, do you use it for more than 1-2 months? Is there a limit of months per year?

  • I thought that the recommendation was to advise decreased frequency of baths in patients with eczema, is this no longer the case?
    Response: No bathing is part of Tx. Once per day not more than 10 min. No soap. Non-soap cleanser 2 times per week max.

  • Ointment vs cream. When to use one or the other?
    Response: I usually use ointment but cream are cosmetically better and better for axilla and groin.

  • Could you please elaborate as to when we should suspect mycosis fungoides? We often see hyopigmented scaly-is lesions.

    Response: Cortico first then moisturizer. However no study to back it up.
