[Primary calcification in Hodgkin's disease].

A chance radiological observation of a calcified mediastinal tumour in 23-year-old woman led to its operative removal. Histologically it proved to be a Hodgkin's sarcoma in a nodular sclerosing form of Hodgkin's disease. There was no other clinical evidence of Hodgkin's foci and, after radiotherapy, the patient has been without recurrence for over one year.
