We report male monocygotic twins with concordant desmoplastic medulloblastoma diagnosed at the age of 20 months. Both tumours were completely removed. As chromosomal loci 17p13 and 9831 are frequently altered in medulloblastoma these regions were analysed in both tumours in detail using restriction fragment length polymorphism and microsatellite analysis. No common aberration was found. The c-myc gene on chromosome 8g21 was not amplified.
