Subungual exostosis

From Wikipedia, the free encyclopedia

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

[edit] 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]

[edit] Treatment

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