Mutilating Keratoderma with Concomitant Alopecia and Keratoses Follicularis Spinulosa Decalvans: X-Linked Olmsted Syndrome and its Response to Isotretinoin.

ABSTRACT

We report a case of mutilating keratoderma with alopecia and keratoses follicularis spinulosa decalvans (KFSD), which was initially diagnosed as ectodermal dysplasia and Olmsted syndrome but was revisited as a case of X-linked Olmsted (XLO) syndrome. We focus on this uncommon entity (XLO) to highlight the differentials of alopecia with palmoplantar keratoderma.
