Comment:
Vacuolated lymphocytes occur most commonly as the peripheral blood manifestation of inherited metabolic disorders, including Niemann-Pick disease Type A, infantile sialic acid storage disorder, Wolman's disease, Mucolipidoses II and III, Salla disease, mannosidosis, Batten disease, GM1 gangliosidosis, neuraminidase deficiency, galactosidosis, fucosidosis, Pompe's disease, aspartylglycosaminuria and rarely, multiple sulfatase deficiency. The metabolic product, which causes vacuolation, depends on the specific enzyme deficiency.
