We report a male child born with complete absence of his external ear, hemifacial microsomia of the right side, high arched palate, a down-turned upper lip and slightly up-slanting palpebral fissures. The features were suggestive of facio-auriculo-vertebral spectrum. Investigations showed a tandem duplication of the short arm of one chromosome 10 with apparent breakpoints at p14 and p15. This case extends the list of chromosomal abnormalities associated with the facio-auriculo-vertebral phenotype and also adds useful clinical information to possible trisomy 10p phenotypes.
