✦ Synopsis
In this report a severely mentally retarded adult female with 9p trisomy/18pter monosomy is described. In addition to a 9p trisomy phenotype this patient presented with multiple cutaneous leiomyomata. The question is raised whether the concurrence of the chromosomal anomaly and the multiple skin tumors in this patient indicates another example of a specific chromosomal deletion (18pter) in a dominantly inherited multiple human tumor.

The trisomy 9p syndrome in a 2-year-old girl with moderate mental retardation is presented. She has a unique karyotype with a de novo isochromosome 9p and a translocation between 9q and 18p.
Structural abnormalities of chromosome 18p mainly consist of isochromosomes of the short arm, which result in tetrasomy 18p. Trisomy 18p is much rarer, and less well characterized. We report on a 12-year-old girl with minor facial anomalies, delayed development, abnormal hands, atopic dermatitis, an
