Repeated incomplete onycomadesis

　

Higashi, Nobuhiko1） 1）Higashi Dermatology Clinic

　

Three cases of repeated incomplete onychomadesis are reported. Repeated incomplete onycomadesis shows a nail plate overlaps each other twice or three times on the nail bed. The lateral side of the nail plate are fixed to the lateral nail fold. Therefore the oldest nail plate has not left out until the nail plate reaches to the distal portion of the nail bed. The treatment of the repeated incomplete onycomadesis was carried out as follows, the tip of the big toe was fixed downward using non-elastic cloth-tape in day time. One case out of three cases was cured.
