@entity705 is a rare condition. To our knowledge, occurrence in the foot has been very rare. We present here a case wherein the @entity1 developed a @entity158 under the tarsal sesamoid. A fifty-one-year-old @entity1 presented at our department with a painful mass on the plantar part of the metatarsal joint of the right big toe. The mass had grown gradually in size for the past 7  months and was associated with @entity158 while walking. Preoperative X-ray and a computed tomography showed that the @entity5 had no continuity with adjacent bone. Intraoperatively, a bony hard @entity5 was located in the subcutaneous tissue plantar to the tibial sesamoid. The mass was firmly attached to the sheath of the flexor hallucis brevis tendon. Macroscopically, the @entity5 was covered with glistering surface. The @entity5 was carefully dissected from the surrounding soft tissues and was removed. It was diagnosed as @entity705 histologically. The @entity1 had no recurrence at 1  year after operation.
