Description

A 12-year-old Japanese girl noticed a subungal small nodule on the first right toe three months prior to her first visit to our hospital. She visited a near-by dermatologist as the nail of the first toe had detached. Since X-ray revealed an abnormalities of the toe bone, she was referred to our department. On examination, a small, bean-sized nodule with smooth surface was palpable below the nail of the first toe. The tip of the nail was lifted upward by the tumor, and a small amount of scale was attached to the surface of the skin. Some part of the tip of the nail was missing. X-ray and CT revealed an ax-like bone shadow protruding from the middle of the extensor aspect of the medial phalanx. With a diagnosis of exostosis, we performed an excision of the tumor opening the nail bed after removal of the nail under conduction anesthesia. Histopathological examination showed a osteochondroma type with a part changing into bone tissue with hyaline cartilage. No postoperative recurrence or nail deformation has been observed.
