Subungual exostosis



Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux.

Contents

Presentation

They tend to be painful due to the pressure applied to the nail bed and plate. They can involve destruction of the nail bed.[1] They are commonly osteochondromas which have identical radiographical and pathological features and never metastasize.

Subungal malignant melanomas can also occur in canines.

They are distinct from subungual osteochondroma.[2]

Treatment

Surgical excision is common and is a very effective mode of treatment.
