Abstract

PURPOSE
Schwannoma is a slow-growing, encapsulated benign peripheral nerve tumor that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma of the foot is rare. This is a report of our experience with a small, deep-seated, and non-palpable schwannoma occurring in the foot. METHODS: A 42-year-old woman presented with the plantar pain of the right foot during 2 years. Physical examination did not identified a palpable mass. She made a clinical diagnosis of plantar fasciitis and was conservatively treated 2 years ago. Since her plantar foot pain was aggravated, she was recently visited again. For the evaluation of her plantar foot pain, sonographic examination of the whole right foot was performed, and it revealed a small hypoechoic hetergenous, deep-seated mass beneath the plantar aponeurosis. At operation, a 0.7x0.6x0.4cm sized, ovoid, yellowish grey mass was removed.
RESULTS
Histology was confirmed that the mass was a benign schwannoma. There were no postoperative complications.
CONCLUSION
Unsusual case of a schwannoma with the plantar foot pain during 2 years is presented. It should be recognized a small, deep-seated, non-palpable schwannoma as a possible cause of plantar foot pain.
