Resumo: A 27 years old female patient, referred for evaluation of lingual tumoration, with evolution of 10 years. The intraoral examination revealed an increase of volume in the left posterior region of the lingual dorsum, asymptomatic, firm to palpation, with no color alterations and maintenance of the mucosa integrity, measuring about 30 mm. Initially an incisional biopsy was performed with diagnostic hypotheses of neoplasm of neural or glandular origin and lipoma. The histopathological examination revealed an encapsulated mesenchymal neoplasm, composed of fusiform and compound cells, either irregular or in palisade, around a central region. The immunohistochemical reaction showed that cells were positive for S100 and negative for CD34. Thus, the histological diagnosis was Schwannoma. The treatment was conservative excision under general anesthesia. Histological examination of surgical specimen confirmed diagnosis of Schwannoma. After 6 months postoperatively, there was no evidence of recurrence.
