Sažetak
Subungvalna egzostoza (SE) osteokartilaginozni je benigni tumor distalne falange prsta. Većinom je lokaliziran na palcu stopala, puno rjeđe na drugim prstima. SE se pojavljuje u oba spola, u pravilu u drugom i trećem desetljeću života, a vrlo rijetko u djece mlađe od osam godina. U radu je prikazana osmogodišnja djevojčica sa subungvalnom egzostozom distalne falange palca desnog stopala. Prezentirala se postupnim rastom bezbolnog, subungvalno smještenoga tvrdog čvora palca desnog stopala, veličine 12 mm u promjeru. Na rendgenogramu stopala koštani izdanak raste iz terminalne falange palca desnog stopala, bez lokalne reakcije periosta. Tumor je kirurški odstranjen pristupom kroz ležište nokta. Histopatološka analiza potvrđuje da se radi o SE-u. Poslijeoperativno u deset mjeseci nije zamijećen recidiv.
Summary
Subungual exostosis (SE) is a benign osteocartilaginous tumor of the distal phalanx of the finger, particularly of the toes. It affects both sexes, the most frequently occurring in the second and third decades of life, and very rarely in children younger than eight years. We present subungual exostosis (SE) in a eith year old female child affecting the terminal phalanx of the right thumb. She presented to us with gradually enlarging, painless, subungual hard nodule on the right thumb, spherical appearance size of 12 mm in diameter. Roentogram of the foot showed bony outgrowth arising from the terminal phalanx of right thumb. Lesion was excised with prior ablation of the nail, and sent for histopathological examination. Histology showed evidence of SE. No recurrence at postoperated site was seen till ten months of follow-up.
