Tracey Vlahovic DPM

What is your diagnosis of the condition shown in the photo on the left?

The idiopathic T-cell-mediated inflammatory condition generally affects several nails. The nails become thin, rough, ridged longitudinally, fissured and can develop a dorsal wing formation of the proximal nail fold (or pterygium formation) over the nail plate. Permanent scarring will ensue unless the matrix damage is addressed.

Which of the following is your diagnosis?

a) onychomycosis
b) psoriatic nail disease
c) trachyonychia
d) lichen planus of the nail
e) onychogryphosis
