“…It has a rare recurrence and only a 5% chance of malignant transformation, which, when it occurs, evolves to complications such as cranial neuropathies, dysphagia, hoarseness and pain. 8,15,16 As in the study by Melzer et al 25 , 2017, in this case, we opted for total excision of the lesion without a safety margin.…”

Schwannomas are benign tumors of the peripheral nerve sheath originating from Schwann cells, which can manifest in head and neck regions and are rare in the oral cavity, especially their involvement in the maxillary alveolar ridge, which is even more atypical. Among all its variants, plexiform schwannoma is characterized by an intraneural multinodular growth.Its differential diagnosis of plexiform neurofibroma is justified by the fact that the latter is pathognomonic for neurofibromatosis and carries great risks of malignancy. In this paper, we present a rare clinical case report of a plexiform schwannoma in a gingival alveolar ridge in a 33-year-old male patient, in which we describe his clinical, histopathological, immunohistochemical aspects and his due approach which, after incisional biopsy diagnosed with plexiform schwannoma, was approached for excision of the lesion by the maxillofacial surgery of Hospital das Cínicas, University of São Paulo Medical School, as well as their respective 7, 14 and 30 day postoperative periods, no signs of recurrence so far. Therefore, in these cases, we emphasize the importance of a thorough clinical examination and the need for additional tests, such as histopathological and immunohistochemical analyzes to determine the correct diagnosis and promote the appropriate treatment.

“…Schwannomas are rare in the upper lip; because of the anatomy of the lips themselves. Lips are composed of connective tissue, fat, skin, and minor salivary glands; so that the lesions that often occur are lipomas, mucoceles, and fibromas [ 8 ].…”

“…Management of Schwannoma is excision of the capsule to avoid recurrence. Schwannoma's prognosis is good, with a low rate of malignant emergence if the tumor is removed completely to its base [ 8 ]. Among the twelve Schwannoma of the upper lip ( Table 1 ), only one had recurrency after 3-years follow up [ 24 ].…”

“…The management of Schwannoma is surgical excision up to the tumor capsule to avoid recurrence. Schwannoma has a good prognosis, with a low rate of recurrency if it is removed until the base of the tumor [ 8 ]. This article reports a rare case of upper lip Schwannoma in a 16-year-old female patient who underwent surgical excision with satisfactory results and no post-excision recurrence.…”
