The refractory nailbed ulceration caused by after nail extraction.

An 82-year-old female patient presented to our clinic with refractory nailbed ulceration accompanied by pain in her left fourth toe. Six months prior, she had undergone nail removal surgery to address a persistent paronychia that had not resolved for four months. Crust, necrotic tissue, and secretion on the nailbed were taken for microbiological examination, and was discovered in culture. The authors first report one refractory nailbed ulceration caused by after nail extraction.
