A family had two siblings with cell-mediated immunodeficiency. In the first case both the thymic dysplasia and dyschondroplasia were discovered during postmortem studies, while in the second patient the existence of a disturbance of cellular immunity was found by various immunological studies. A review of the literature for other cases of immune deficiency disease associated with abnormalities involving other tissues suggests that such associations may not be coincidental in nature.
