Abstract

CONTEXT: Mosaic trisomy 9 is considered to be a rare chromosomal abnormality with limited survival. Our objective was to report on two patients with mosaic trisomy 9 presenting unusual findings and prolonged survival. CASE REPORTS: The first patient was a boy aged six years and five months presenting weight of 14.5 kg (< P3), height of 112 cm (P10), head circumference of 49 cm (P2), prominent forehead, triangular and asymmetric face, thin lips, right microtia with overfolded helix, small hands, micropenis < 1 year). Further reports will be critical for delineating the clinical features and determining the evolution of patients with mosaic trisomy 9CONTEXTO: A trissomia do cromossomo 9 em mosaico é considerada uma anormalidade cromossômica rara e com limitada sobrevida.
