Hodgkin lymphoma of the maxillary sinus: an unusual occurrence.

The maxillary sinus is a rare anatomic site for Hodgkin lymphoma, as only 1 such case has been previously reported in the literature. Nevertheless, we recommend that lymphoma be considered in the differential diagnosis of a mass that involves the maxillary sinus or any other unusual extranodal site in the head and neck. Lymphoma in a patient who presents with disease in an unusual site and without lymphadenopathy is difficult to diagnose. We report the case of a 60-year-old woman who presented with nasal congestion and obstruction. Examination revealed an abnormal-appearing mucosa involving the maxillary sinus. Subsequent evaluation led to a diagnosis of Hodgkin lymphoma. Because making such a diagnosis is difficult, close attention to radiologic and pathologic findings is important. Our review of the literature revealed that treatment commonly includes chemotherapy and radiotherapy, which yield excellent outcomes. The current standard of care for patients with similar-stage Hodgkin lymphoma at other sites can guide the treatment course for patients with extranodal Hodgkin lymphoma.
