Case 15-1985

To the Editor: In a recent CPC (Case 15–1985) (April 11 issue),¹ in which a patient with Schmidt's syndrome was described, the thyroid gland was found to be enlarged clinically but of “normal” size at postmortem examination (despite severe autoimmune thyroiditis on histologic study). I wish to take exception to Dr. Gang's reference to the normal weight of the thyroid as 30 to 70 g with a mean of 40 g. In a report from the Mayo Clinic by Mortensen et al. in 1955, the mean weight of thyroids in the Great Lakes region of the United States was 25.
