Rhabdoid tumours

Rhabdoid tumours are rare and extremely aggressive tumours of early childhood. They occur in a number of locations: 

This article touches on the generalities of these tumours, but each is then discussed separately. 

Epidemiology

Almost all reported cases of rhabdoid tumours, regardless of site of origin, occur in young children, between birth and 2 years of age 4

In approximately 10% of cases of renal malignant rhabdoid tumours, patients then subsequently develop intracranial atypical teratoid/rhabdoid tumour (AT/RT) 2

Pathology

Irrespective of site of origin, rhabdoid tumours share deletions in the long arm of chromosome 22, mapped to the INI1 gene, believed to be a tumour suppressor 1,4

These tumours contain characteristic rhabdoid cells, so-called on account of the light microscopy resemblance to skeletal muscle cells 2
