A 42-year-old female patient reported diffuse toothache associated with difficulty chewing and a lesion in the oral cavity for approximately 3 months. The patient's medical history showed a diagnosis of mediastinal sarcoma and she was undergoing chemotherapy. Extraoral examination showed no changes. In the oral cavity, a nodular lesion with an ulcerated surface in the right retromolar triangle associated with the occlusion trauma promoted by element 18 was observed. Panoramic radiography showed a radiolucent lesion of imprecise limits without promoting root resorption in adjacent teeth. Bone scintigraphy revealed a blastomatous lesion in the mandible and oral cavity, suggesting bone metastasis. Incisional biopsy was performed, and histological sections stained in hematoxylin and eosin showed low-grade ulcerated fusocellular sarcoma, consistent with fibrosarcoma. The patient followed chemotherapy with doxorubicin and dacarbazine but died from treatment complications.
