[Chromosomal translocation (2;13) in disseminated rhabdomyosarcoma].
A 12-year-old male with a disseminated alveolar rhabdomyosarcoma is reported. The diagnosis was difficult because of the clinical manifestations and the histological patterns of the bone marrow and a chest wall tumor. Diagnosis was confirmed through the histologic picture of a gum biopsy and the karyotype of the tumoral cells of the bone marrow. Chromosome study revealed a hypotetraploid cell line with the translocation (2;13) characteristic of this type of neoplasias. The usefulness of chromosome studies in solid tumors of childhood is emphasized.
