Resumo: A 49-year-old female was referred to a stomatologist due to complaints of enlargement and pain associated with a vascular lesion that had been monitored for two years. Her medical history revealed no systemic diseases. During the intraoral examination, a blue-purplish nodule was observed on the oral mucosa of the right lower lip, and exhibited a fibrous region upon palpation with 1.0 cm in its greatest dimension. An incisional biopsy was performed, and histopathological examination revealed the presence of cords or nests of polygonal to slightly spindled epithelioid cells, with formation of intracytoplasmic lumina, surrounding small vessels with perineural infiltration. Immunohistochemistry markers were positive for CD34, CD31, factor VIII-related antigen (FVIIIRAg), FLI1, D2-40, and ERG, confirming the diagnosis of epithelioid hemangioendothelioma (EHE). The patient was referred to a head and neck surgeon for complete removal of the EHE. She has been under observation for two years with no signs of recurrence.
