爪下角化棘皮瘤伴趾骨溶解后再骨化的自然退化

摘要

cqvip:A 45-year-old man presented with a rapidly enlarging keratotic lesion of the distal subungual right middle finger. An X-ray of the digit revealed a well-d efined cup-shaped lytic lesion of the phalynx underlying the subungual nodule. The lesion resolved spontaneously with reossification of the underlying bony def ect. The clinical history and X-ray is consistent with a diagnosis of spontaneo usly resolving subungual keratoacanthoma.
