Resumo: A male patient, 56 years old, was referred to the oral diagnosis service with a lesion on the upper lip with an undefined duration of evolution. On intraoral physical examination, swelling was observed on the upper lip, with a color similar to the surrounding mucosa, rounded shape, well-defined borders, fibrous consistency, and mobility. Based on these characteristics, the initial diagnostic hypothesis was fibrous hyperplasia. An excisional biopsy was performed, and the specimen was sent for histopathological examination, which revealed a well-circumscribed, non-encapsulated lesion characterized by the proliferation of spindle-shaped cells arranged in varying proportions of Antoni A and Antoni B patterns. Immunohistochemical analysis showed positivity for S-100 and Sox-10, confirming the diagnosis of schwannoma. The patient is under clinical follow-up and has shown no signs of recurrence for twelve months.
