There is an expansile lucent lesion involving the tuft of the second phalanx with a cortical defect in the distal most aspect. There is scalloping of the volar aspect of the distal phalanx on the lateral view, suggesting possible remodeling from adjacent soft tissues. This lesion is likely benign in nature and may represent a giant cell tumor of the tendon sheath or an enchondroma. Other benign etiologies such as an epidermal inclusion cyst is also possible given the history of prior trauma to this region. A metastatic lytic lesion is a far less likely considered, given location. Incidental note of clubbing of the nailbeds.
