Abstract
Chromosomes from a patient with mycosis fungoides were examined in detail with banding techniques. Hyperdiploid cells from a lymph node had common anomalies of certain chromosomes which formed three similar clones. The abnormalities involved chromosomes No. 1, 2, 5, 8, 9, 10, 14, and 18, in addition to an unknown small metacentric marker (M3). Although there were a number of mitotic cells in peripheral blood cultured both with and without PHA, none of the few cells with abnormal karyotypes was similar to the clonal cells of the lymph node. One of the abnormalities in the lymph node was a 14q rearrangement, which could be the result of a translocation of Nos. 8 and 14 involving a third chromosome, No. 2. An abnormality in the blood resulted from a translocation between the long arms of Nos. 1 and 14. These findings could be useful for studies in which mycosis fungoides is compared with the Sézary syndrome and other lymphoid malignancies. Cancer 42:2262–2268, 1978.
