Diffuse toxic goiter is a common disease of the thyroid gland. As orga
nospecific autoimmune condition the disease is not infrequently combin
ed with endocrine ophthalmopathy and in this connection a more precise
preparation of the patients to surgery is found to be mandatory. Elde
rly persons demonstrate atypical patterns of the disease course (insig
nificant enlargement of the gland, manifest depression, isolated cardi
al disorders without other symptoms of thyrotoxicosis, resistance to t
hyrostatic treatment). The patients need a lifelong dyspensary follow-
up as diffuse toxic goiter is a condition of a relapsing type.
