Subungual osteochondroma: Nail sparing excision

Abstract

Subungual osteochondroma is a relatively uncommon benign bone tumor affecting mostly children and young adults, and is a major source of pain and nail deformity. Treatment consists of marginal excision and meticulous wound closure. In this report, we present three cases of subungual osteochondroma arising from the dorsal aspect of distal phalanx of the great toe, which were managed by marginal excision with preservation of nail apparatus under digital block anesthesia with the use of a ring tourniquet. We emphasize on the use of ring tourniquet made by glove's finger and the technique of preserving the nail apparatus to prevent nail deformity. At final follow-up, there is no evidence of recurrence or nail deformity with good functional and cosmetic result.

Subungual exostosis and subungual osteochondromas: a description of 25 cases

“…There is a paucity of case reports on SO . Some previous reports suggested that cases diagnosed as SE were in fact SO .…”

Subungual Osteochondroma: A Diagnosis to be remembered

“…Although osteochondromas are the most common bone tumors, representing 10 to 15% of the totality, subungualosteochondromas is quite rare [1][2][3][4]. It is a benign osteocartilaginous tumor that usually involves the phalanges of the toes or fingers, affecting most commonly the distal phalanx of hallux [4].…”

“…The first description is attributed to Dupuytren, in 1817. The author described as a bony outgrowth of the distal phalanx [3].…”

“…Subungual osteochondromas occurs mainly in adolescents and young adults. Although there are some discordant works, most authors found an equivalence between the sexes [2,3]. The most common topography of involvement is the distal phalanx of the hallux, however it can occur on any finger or toe [4][5][6].…”
