We thank Drs Wilkinson and associates for their significant comments concerning our recent Archives article. We agree with them that if ridging alone is the sole manifestation of change in the nail plate, this may represent something other than lichen planus. However, if all of the features of the patients described by Hazelrigg et al1 are present (splitting, thinning, brittleness), we interpret this as lichen planus. Others who are interested in diseases of the nails share our view (N. Zaias, MD, oral communication, September 1978, and R. Baran, MD, oral communication, September 1978). We hope to learn more in the future about this interesting entity.
