Abstract
Five cases of T-zone lymphoma were investigated with histologic, immunologic, and cytogenetic methods. The chromosome analyses were performed on lymphoma cells prepared immediately after removal of the lymph nodes. The chromosomes involved in structural rearrangements were nos. 1, 2, 3, 4, 14, and Y. Numbers 3, 5, 6, and 13 were lost by some tumors, and nos. 3 and 9 were gained. Chromosome 3 was involved most often in structural and numerical aberrations, whereas 14q+ markers occurred in only one case. The importance of multidisciplinary studies is pointed out.
