Schwannoma intraósseo: Relato de caso e revisão da literatura

Abstract: ResumoSchwannomas são tumores benignos oriundos de células da bainha neural cuja apresentação intraóssea é rara. Estima-se que os schwannomas intraósseos representem 0,2% de todos os tumores ósseos. Schwannomas podem acometer diferentes ossos do esqueleto, como a mandíbula, o sacro, corpos vertebrais, a ulna, o úmero, o fêmur, a tíbia, a patela, a escápula, costelas e ossos da mão. Apenas quatro casos que acometeram o calcâneo foram descritos na literatura. No presente trabalho, os autores relatam o caso de um… Show more

“…The histological findings of intraosseous schwannomas are similar to the soft tissue schwannomas with two major components which consists of: a highly ordered cellular component (Antoni A) and a loose myxoid component (Antoni B), and some cases present what is called a verocay bodies which is form from a nuclear palisade alternating with fibrillar areas. Then the diagnosis is supported by the findings for S100 protein on immunohistochemical evaluation [1] , [2] , [6] , [8] .…”

“…As Schwann cell function is to form the myelin sheath on peripheral nerve, schwannomas can virtually develop in almost any body region. But the most common predilection sites of schwannomas are around head and neck region as those area contains rich innervation from either cranial or spinal nerve [1] , [2] .…”

“…Achados importantes como neurilemomas bilaterais do nervo vestíbulococlear caracterizam uma condição hereditária: a neurofibromatose tipo II (NF2) (Neville, 2009). Esse tumor pode acometer qualquer idade sem predileção por sexo e/ou etnia, porém apresenta maiores frequências entre a 4ª e 6ª década de vida e maiores incidências em mulheres (Drumond, 2018).…”
