Co-Occurrence of Pallister-Killian Syndrome and Burkitt Lymphoma in a Patient with Near-Normal Neurocognitive Development.

ABSTRACT:

Background

Pallister-Killian syndrome (PKS) is typically recognized by its features that include developmental delay, seizures, sparse temporal hair, and facial dysmorphisms. PKS is most frequently caused by mosaic supernumerary isochromosome 12p.
