Abstract
|
|
|
Purpose: Nerve sheath myxoma is a rare cutaneous neoplasm originating from the peripheral nerve sheath and divided into three groups : myxoid, cellular and mixed type. There is a controversy on it’s origin whether schwannian cell or perineurial differentiation, or anything else. Myxoid nerve sheath myxoma is asymmptomatic, soft, papule or nodule in middle-age adults. We report a case of myxoid nerve sheath myxoma on the fingertip.
Methods: A 53-year-old woman presented with a painful, 0.4 × 0.4 × 0.6 cm sized, corn shaped nodule on the left 3rd fingertip. We put into surgical excision and studied it by histopathologically and specific immnohistochemical stain.
Results: The tumor has well defined nodules separated by thin fibrous connective tissue with abundant myxoid stroma and were positively stainded for S-100 protein, NSE and GFAP. After surgical treatment it was healed without recurrence.
Conclusion: Nerve sheath myxoma is rare neoplasm and located mainly on face, but very rarely on the fingertip. We report a case of painful myxoid nerve sheath myxoma located on the 3rd fingertip.
