contactable and reported clinically significant improvement in itch scores. We further performed a sensitivity analysis assuming that all the subjects who stopped treatment or defaulted had no improvement in their outcome measures at 6 weeks and repeated the comparisons above (n = 40). The overall improvements in all the outcomes remained statistically significant (P ≤ 0.001). Treatment of scrotal LSC is challenging. Limited evidence suggests that topical calcineurin inhibitors may be useful in women with vulvar LSC. In this study, 0.1% tacrolimus ointment was found to be effective in reducing itch intensity in scrotal LSC, with concurrent improvements in itch frequency, sleep, quality of life and physical extent and severity of the lesions. In addition to its immunosuppressive and anti-inflammatory effects, tacrolimus ointment has been shown to have a separate antipruritic effect. Tacrolimus favours the phosphorylation of transient receptor potential vanilloid 1 (TRPV1) ion channels on neurons, resulting in an initial release of substance P, and this likely explains the side effect of initial burning sensation. Subsequently, the desensitization of sensory neurons inhibits transmission of itch signals. This disrupts the itch-scratch cycle which is a cornerstone in the pathogenesis of LSC. The safety profile of topical calcineurin inhibitors has been well established, with the most common adverse effect being a temporary burning sensation at the application site. In our study, a warm or burning sensation was reported in 12 (30.0%) of 40 subjects, which was mild and transient in six subjects. This was intolerable or was accompanied by a significant increase in itch in the other six subjects, who discontinued treatment themselves. No other adverse effects were observed. In conclusion, topical 0.1% tacrolimus ointment, when tolerated, was an effective and safe treatment for scrotal LSC in our study population.
