Abstrakt: A 56-year-old woman presented with a four-month history of right-sided facial pain. Upon intraoral clinical examination, a swelling was observed in the right side of the mouth floor. This swelling had a hardened consistency, normal mucosa color, well-defined boundaries, and was sessile in nature. An occlusal radiograph of the mandible did not reveal any radiographic images associated with the lesion. An aspiration puncture yielded negative results. Initially, the diagnosis was considered to be Pleomorphic Adenoma, which is a benign salivary gland tumor. However, due to suspicion of malignancy, an incisional biopsy was performed. The histopathological examination revealed cuboid epithelial cells with basophilic nuclei and clear cytoplasm, organized in islets and cords that appeared to have a tubular or ductal aspect. Additionally, in some of these ducts, basophilic material suggestive of mucus was present, and tumor cells were found in close proximity to nerve fillets and blood vessels. These findings were consistent with Adenoid Cystic Carcinoma. The proposed treatment plan by the head and neck surgeon involves surgical excision combined with chemoradiotherapy. The significance of this case lies in its uncommon presentation and diagnostic challenges. [ABSTRACT FROM AUTHOR]
