Dermal Schwannoma (Neurilemmoma): A Peculiar Foreign Body Reaction?Kneitz, Hermann MD; Weyandt, Gerhard MD; Meissner, Christoph MD; Gebhart, Edith PhD; Bröcker, Eva B MDThe American Journal of Dermatopathology: June 2010 - Volume 32 - Issue 4 - p 367-369 doi: 10.1097/DAD.0b013e3181bb1972 Extraordinary Case Report Abstract Author Information Schwannoma is usually a subcutaneous benign neoplasm that derives from nerve sheath. Pain and neurologic symptoms are uncommon, and exclusively dermal tumors are very rare. Solitary schwannoma has a traumatic origin in some cases, and rarely occur as a part of neurofibromatosis or schwannomatosis. An association of deeply located schwannoma with foreign material has been reported in very few cases. To our knowledge, we present the first case of a painful dermal schwannoma in association to foreign material.
