title: Cytogenetic abnormalities in thyroid adenomas.
abstract: Cytogenetic investigations using short-term cultures are reported in six thyroid adenomas. Clonal and nonclonal numerical chromosomal changes were present in two tumors. In two of the four remaining, nonclonal numerical and structural abnormalities were observed, whereas only normal karyotypes were found in the other two. Chromosome 10 and 17 were involved in several cases, although no common clonal changes could be detected. The present studies show that thyroid adenomas, benign tumors of an endocrine gland, may have chromosomal abnormalities, as described for other benign tumors.
