Introduction: schwannoma is one of the tumors derivates from neural sheet, characterized by a slow growing, symptomless in some cases, rare in the oral cavity, unknown etiology which definitive diagnosis should be made by the anatomopathologic analysis. Not any reports at the Cubans or Yemenis electronic journals were founded. This observation in conjunction with the not patognomonic way of presentation and rareness of the lingual Schwannoma, motivated us to report this case. Objective: to present a case of rare oral tumor, with uncommon tongue location. Case presentation: a 26 years old male patient, from Yemen was attended at the Maxillofacial Service of Aden University, complaining about a mass on the tongue since one year ago which was asymptomatic, but about ten days ago the patient suffered from a masticatory trauma that produced some discomfort. Initial diagnosis was as pyogenic granuloma; excision and biopsy were made under local anesthesia to achieve the final diagnosis. Not any complications and a favorable postsurgical evolution were observed. The conclusion of the histopathological study was lingual Schwannoma. Discussion: different benign and malignant tumors of the tongue that make confusion in the diagnosis of this disease were analyzed and the not patognomonic behavior of this affection was taking into account. Many authors report about the posterior localization of this tumor, but in our case was localized at the tip of the tongue. Conclusions: Schwannoma is a rare disease of the oral cavity that requires histopathological analysis for the final diagnosis and has a good postsurgical prognosis.
