Batten disease histology (vacuolated lymphocytes)
Neuronal Ceroid Lipofuscinoses (commonly referred to as Batten disease) are among the most common neurometabolic disorders. These are initially investigated by the measurement of the enzymes palmitoyl protein thioesterase (PPT) and tripeptidyl peptidase 1 (TPP). This additional test for vacuolated lymphocytes (sometimes referred to as Batten histology) may be required if initial enzyme tests are normal and there is still a strong clinical suspicion.
