Hodgkin lymphoma occupies an enigmatic place among malignant lymphomas. Thomas Hodgkin was appointed to the post of Inspector of the Dead and Curator of the Museum at Guy’s Hospital in 1826. In his role as a morbid anatomist, he noted a peculiar appearance of the lymph nodes and spleen in six patients and was shown paintings of a similar case from France by his friend Robert Carswell, the first professor of pathology at University College Hospital. Hodgkin presented details of these cases in two lectures given to the Medical-Chirurgical Society in 1832 that were subsequently published in the transactions of that society under the title ‘On some morbid appearances of the absorbent glands and spleen’. This paper would have probably faded into obscurity had not Sir Samuel Wilks, a distinguished physician at Guy’s Hospital, described similar cases between 1856 and 1877 and, noting Dr. Hodgkin’s precedence, named them as Hodgkin’s disease.
