Alopecia universalis with twenty-nail dystrophy (trachyonychia).
A 43-year-old man presented with long-standing trachyonychia of all 20 nails, which worsened after the onset of alopecia universalis 18 months ago. Trachyonychia can be associated with alopecia universalis although the treatment strategies of both conditions differ. The principle of treating trachyonychia may involve regulating the differentiation of keratinocytes and/or reducing inflammation in the nail fold or nail matrix while treatment of alopecia universalis involves immunomodulation.
