Acro-osteolysis (synonym phalangeal osteolysis) refers to the resorption of one or more of the distal phalanges of the hands or feet.1 Two characteristic radiologic variants have been described, and may coexist in the same patient.2 In the transverse type, linear bands of resorption are evident in the shaft of the distal phalanx, perpendicular to its long axis. In the longitudinal type, there is resorption of the tuft of the distal phalanx. Although case reports tend to emphasize these radiologic findings, little attention is paid to nail changes. We report idiopathic acro-osteolysis in an otherwise healthy 10-year-old girl presenting to our dermatology service with nail dystrophy. We performed a literature review for similar cases and for nail changes previously reported in acro-osteolysis.
