title: [Clinico-pathological study of atypical adenomas of the thyroid].
abstract: A total of five cases of atypical adenomas of the thyroid were clinicopathologically examined to clarify their malignant potential and incidence. These adenomas showed both structural and cellular atypia when compared with follicular adenoma of the usual type, A follow-up study after surgery revealed neither metastasis nor postoperative recurrence. Therefore it has been concluded that an atypical adenoma of the thyroid can be regarded as a benign neoplasm.
