Resumo: A 62-year-old male was referred for management of oral squamous cell carcinoma (OSCC), previously diagnosed in another service. The patient complained of oral discomfort persisting for 10 months, reported being a social drinker, and denied smoking. Intraoral examination revealed a vegetating, hardened lesion, measuring 3.0 cm, in transition between the retromolar trigone, soft palate, and buccal mucosa. Incisional biopsy was performed, and microscopy showed malignant epithelial cells proliferate and invade the surrounding stroma as islands and cords of epithelial cells, with the presence of cystic areas, resembling mucoepidermoid carcinoma (MC). The histological findings led to a diagnosis of MC or OSCC with cystic areas. Based on the correlation between the morphological, immunohistochemical, and histochemical findings, the diagnosis of OSCC was supported. The patient is currently being followed up for further therapeutic intervention. Recognizing the histological variants of OSCC is important, due to the similarity with other neoplasms. Support: CAPES
