Pimecrolimus is an ascomycin macrolactam. It is a specific calcineurin inhibitor that allows topical application. The highly lipophilic nature of this compound reduces the risk of systemic absorption through normal and inflammed skin. Pimecrolimus shows activity not only against T-cell activation, but also against mast cells and pruritus. Pimecrolimus 1% cream is approved for atopic dermatitis, and also has a great potential in other inflammatory skin diseases. Clinical trials have been performed in contact- and seborrhoeic dermatitis, genital lichen sclerosus, intertriginous psoriasis and cutaneous lupus erythematosus. In other diseases, the available data are limited to small case series, or individual cases of graft-versus-host disease or Netherton's disease. Although the use of calcineurin inhibitors in the treatment of vitiligo is promising, detailed studies with pimecrolimus and ultraviolet-irradiation are necessary and there is a need for prospective randomised, double-blind controlled trials.

Netherton's syndrome (NS) is a rare autosomal recessive disease comprised of ichthyosis in the form of ichthyosis linearis circumflexa, hair shaft defects and atopic manifestations with an elevated IgE level. Various therapeutic options have been used in NS with variable success. Tacrolimus and pimecrolimus belong to the family of calcineurin inhibitors. They bind cytoplasmic proteins and the resulting complex binds calcineurin, inhibiting its ability to dephosphorylate the nuclear factor of activated T cells, thus suppressing gene transcription. There have been conflicting reports of the usefulness of tacrolimus in NS patients, with systemic absorption being the main adverse outcome. Here we report four Saudi siblings (two boys and two girls) with NS who were treated with topical tacrolimus and pimecrolimus with good control of their skin disease without any toxic effect. To our knowledge, this is the second report of the use of topical pimecrolimus in NS in the English literature.
