Аннотация
BACKGROUND: Small cell neuroendocrine carcinoma (SCNC) of the oral cavity is a poorly differentiated, high-grade and very aggressive tumor with a poor prognosis.
CASE DESCRIPTION: A 64-year-old, Caucasian, smoker man consulted for an ulcero-necrotic, exophytic, lesion of the right retromolar trigone. Haed&neck CT scan showed a right tonsillar tumor lesion. The 18F-PET scan confirmed the presence of a right, highly hypermetabolic tonsillar lesion and two homolateral, cervical lymph nodes. Histology and immunohistochemistry were consisted with the diagnosis of a primary SCNC of the oral cavity. As the tumor was locally advanced and unresectable, the patient underwent a definitive radio-chemotherapy with a cisplatin/etoposide combined regimen (4 cycles). The treatment was well tolerated and led to a complete tumor response.
CONCLUSION: The particularity of this case relies on the rarity of the oral SCNC, its difficult and challenging diagnosis, and the complexity of its management that is not validated by large clinical trials, data being extrapolated from small cell lung cancer. In our case, the patient presenting a locally advanced tumor was treated by a combined radio-chemiotherapy leading to a complete tumor regression. The patient's follow up is too short to assess the real benefit of this treatment on overall survival.
