We report on a 46 year old female with a new chromosomal finding [46,XX/47,XXX/47,XX,+8] who was referred for ovarian failure. The clinical presentation was highly unusual and the patient does not exhibit the characteristic phenotype of trisomy 8 syndrome. Interphase cytogenetics using FISH-technique revealed discrepancies with a different population of cells when compared with its metaphase index. Therefore, it is advised that patients with mosaic karyotypes should be evaluated by analyzing metaphase as well as interphase nuclei labeled with chromosome specific molecular tags, especially in the situations where the incidence of a mosaic cell line is very low. Nevertheless, in a cost-conscious environment, we must exercise caution prior to making universal recommendations concerning the usefulness of medical devices which are increasing at a logarithmic rate.
