Distal phalangeal metastasis of a chondrosarcoma presenting initially as bilateral onycholysis.
Onycholysis is the detachment of a nail plate from its distolateral attachments. There are numerous aetiologies: congenital, traumatic, microbial, toxic, dermatological, systemic and benign or malignant tumours. We report a case with onycholysis of the ring-fingers of both hands whose symmetrical and bilateral characteristics temporarily confused the diagnosis.
