title: Cytogenetic study of neuroendocrine carcinoma of Merkel cells.
abstract: We describe the cytogenetic study of a neuroendocrine tumor of Merkel cells which appeared in a patient following a heart transplant. An abnormal karyotype was observed in a metastatic lymph node. The abnormality includes two markers derived from the long arm of chromosome 1, while maintaining two normal chromosomes 1.
