An itchy rash on the fingertips - a case study.

A case study A previously healthy woman, aged 37 years, presented with a 4-week history of pruritic periungual rash and subungual pain. Physical examination revealed scaly, fissured, erythematous plaques around her fingernails (Figure 1). Underneath the acrylic artificial nails that she had been wearing for 6 weeks, onycholysis and nail bed hyperkeratosis were evident. Oral terbinafine and amorolfine nail polish were prescribed by the general practitioner but had no clinical benefit.
