GRANDO, L.J. et al. Maxillary sinus carcinoma in a patient with oral lichen planus: a case report. Av Odontoestomatol [online]. 2013, vol.29, n.4, pp.185-190. ISSN 2340-3152.

Patient with difficult-to-manage oral lichen planus, with relapses and exacerbations over a 10-year period, presented with a large ulcerative and foul-smelling intraoral mass in the left maxillary region. The initial clinical diagnosis indicated squamous cell carcinoma with possible association with previous history of lichen planus at the site. The incisional biopsy confirmed the presence of squamous cell carcinoma. The imaging exams revealed extensive involvement of the adjacent maxillary sinus cavity, with areas of bone erosion. The association of clinical, imaging and laboratory data indicated maxillary sinus carcinoma. The patient underwent maxillectomy and adjuvant radiation therapy. Local relapse and deterioration of symptoms occurred, and palliative chemotherapy was then used. The patient was refractory to chemotherapy and died one year later.
