Glomus tumors are benign tumors found mainly in the digits of the hands, but rarely in the toes. In this study, we report a case of glomus tumor in the hallux. A 63-year-old female patient visited our department for a 10-year history of right hallux nail pain of unknown cause. Physical examination revealed redness, tenderness and nail deformity. On MRI examination, low iso-intense signals were observed on T1 images and high-intensity signals in a tumor under the nail bed on T2 images. We diagnosed it as a glomus tumor of the hallux and excised the tumor under microscopic guidance, followed by confirmation by histological examination. After the surgery, the patient reported no pain in the hallux. MRI examination revealed no signs of recurrence and no deformity of the nail. For glomus tumors, early diagnosis is important and they may occur outside of the digits.
