We report a case of Hodgkin's lymphoma in a patient aged 75, presenting with acute cardiopulmonary insufficiency, hospitalized in a geriatrics ward. The deterioration of his general condition and the discovery of several lymph nodes led us to perform an aspiration of a lymph node and a bone marrow biopsy. Reed-Sternberg cells, pathognomonic of Hodgkin's disease were identified on the smears and biopsy sections. Due to the poor condition of the patient, it was decided not to treat with chemotherapy. The diagnostic approach and treatment strategy of Hodgkin's disease are summarized in this paper, especially the particular features of the disease in the elderly.
