Wolman disease: diagnosis by leucocyte acid lipase estimation

Wolman disease is a rare fatal autosomal recessive disorder caused by absence of acid lipase enzyme leading to accumulation of cholesterol ester. Hepatosplenomegaly is a constant feature and occurs as early as fourth day of life. Progressive mental deterioration may occur after few weeks of onset of symptoms. Adrenal calcification seen on X-ray abdomen, USG or CT scan is the hallmark of Wolman disease. For the first time in Indian literature, the authors report a case of Wolman disease that was confirmed by acid lipase enzyme estimation.
