title: [Intralaryngeal struma].
abstract: This is the first report of an intralaryngeal struma in which particular case the thyroid tissue was connected with the extralaryngeal struma because of a defect in the thyroid cartilage below the beginning of the left vocal cord. Pathogenetically speaking, it cannot be fully explained how this could develop. Hypothetically, the thyroid tissue had already invaded the larynx before the median had fused with the lateral chondrification centers of the thyroid cartilage (before the 10th-13th embryonic week); later, in the course of the struma disease, the struma developed.
