Cytogenetics of six follicular thyroid adenomas including a case report of an oxyphil variant with t(8;14)(q13;q24.1).

Cytogenetic analyses were performed on six follicular thyroid adenomas. Five had normal karyotypes and one, an oxyphil adenoma, had a t(8;14)(q13;q24.1). This patient also had a history of pleomorphic adenoma of the parotid gland. This clonal abnormality may suggest a primary genetic lesion in this patient who had two different benign neoplasms.
