Early stage onychomadesis presenting as painful swellings of proximal nail folds.

Two Korean men complained of painful erythematous swellings of the proximal nail folds. When we removed the overlying nail plates, we observed new ones growing under the old ones. These painful swellings disappeared after the affected nails were extracted. We found typical onychomadesis in another finger during the follow-up, suggesting that the initial condition marked the onset of onychomadesis. Because both patients had plaster casts removed recently and histories of trauma, it was hypothesized that trauma might be responsible for this peculiar condition.
