We report a rare care of a symptomatic sesamoid in the interphalageal joint of the great toe. A 29-year-old woman had a painful keratosis on the plantar side of the right great toe for 10 years. Plain radiographs showed a 5×10cm-sized sesamoid on the plantar side of the interphalangeal joint. Ultrasound sonography showed the sesamoid between the capsule and flexsor hullcis longus tendon. We resected the sesamoid using the plantar approach. At 6 months after surgery, she had no pain in the IP joint of the right great toe. Some authors have reported that a sesamoid on the interphalangeal joint of the great toe in adults was identified 95.5% of the time in anatomic assessments and 56.3% of the time in radiographic assessments. Although many people have an asymptomatic sesamoid on the interphalangeal joint of the great toe, it should be included in a differential diagnosis of painful keratosis on the plantar side of the great toe.
