title: Subungual nodule of the great toe.
abstract: An otherwise healthy male, 17 years of age, presented with a 2 year history of an enlarging lump under the right great toenail. There was no history of trauma. Examination revealed an exophytic, non-tender, fixed, firm flesh-coloured subungal nodule on the dorsal aspect of the right great toe. The lesion was about 10 mm in diameter and was associated with nail plate deformity and onycholysis.
