The incidence of thyroiditis lesions in nodular goiter.

On the basis of clinical and biological data, surgical investigation and histopathological aspects, a number of 35 localized froms of thyroiditis have been given a diagnosis in order to assess their incidence in case of both nodular goiter and chronical inflammatory processes at the thyroid gland level. Three possibilities are considered: the proper inflammatory lesions--granulomatous, lymphoplasmocitary and ligneous thyroiditis, the cystic formations circumscribed by the glandular tissue with inflammatory signs as well as the association of thyroid cancer with chronic thyroiditis--seldom reported in literature--upon which 2 observations have been made.
