Abstract:
Herein we report a case of subungual osteochondroma in a male patient. Although there have been several reports about cases of subungual exostosis in Korea, a case of subungual osteochondroma had not been reported until now. Osteochcndromas are clearly different disease entities from exastosis in that they have diagnostic hyaline cartilaginous caps instead of the fibrocartilages in subungual exostosis. Additioaally, subungual osteochondroma is a very rare type having an incidence rate of less than 1% among all osteochondromas. Our patient was an 18-year-old male with a solitary woody mass on his right great toe that was painfuL A surgical excisional biopsy following a nail plate avulsion showed the characteristic hyaline cattilaginous caps enclosing bony trabecula connected with the inferior cortical bone.
