INTRODUCTION: Non-Hodgkin lymphomas are common cancers that can develop in the upper aero-digestive tract. We describe a case of a large B-cell palatine lymphoma with spontaneous clinical regression. CASE: A 58-year-old female patient presented with a sub-mucosal lesion of the hard palate. CT scan and magnetic resonance imaging revealed a lesion invading the right posterior palatine canal. At the second consultation, 15 days after performing the biopsy, the lesion had disappeared. PET scan proved the absence of lesion. Lymph node biopsy supported the diagnosis of large B-cell lymphoma. DISCUSSION: Large B-cell lymphoma of the hard palate is a rare disease. Only 27 cases have been described in the international literature. The anatomopathological analysis is often difficult to perform. The final diagnosis is often made by immunochemistry. The usual treatment is R-CHOP chemotherapy (cyclophosphamide, adriamycin, vincristine, prednisone combined to rituximab) with a 5-year survival rate at 55%.
