Spontaneous photo-onycholysis.


Three cases of onycholysis following, and apparently caused by, sun exposure are reported. No case was associated with drug ingestion or demonstrable metabolic abnormality. Cutaneous phototesting of all patients with an irradiation monochromator was within normal limits, although the action spectrum for the defect may lie in the ultraviolet-A (UV-A) region. This appears to be the first report of spontaneous photo-onycholysis.
