Solitary nodule of the great toe

We describe a 21-year-old woman with a subungual exostosis exhibiting both skin and nail findings. The patient presented with a firm, flesh-colored, n ontender, subungual nodule in the distal nail bed of the great toe. Radiogr aphic examination revealed focal calcification of the nodule, with direct c ommunication to,the underlying phalanx. Subungual exostosis should be consi dered in the differential diagnosis of any digital mass. Surgical excision, followed by curettage of the base, is the treatment of choice.
