RESUMEN

Wolman's disease is a rare autosomal recessive lysosomal storage disease. A recent review indicates that approximately 50 patients have been reported in the world. Reports of patients from the Arabian peninsula are rare due to lack of awareness among pediatricians. We retrospectively reviewed the clinical, radiological, biochemical and histopathological findings of four Saudi patients diagnosed with Wolman's disease at King Faisal Specialist Hospital and Research Centre. The diagnosis was confirmed by deficient acid lipase activity in the leukocytes and fibroblasts, which was measured using 4-methylumbelliferyl palmitate. All patients were failing to thrive with progressive hepatosplenomegaly. Abdominal x-ray revealed calcifications which were confirmed on abdominal CT scan. Peripheral blood film showed vacuolated lymphocytes and the bone marrow aspiration showed foamy histiocytes. Liver biopsy in one patient showed marked steatosis and elliptical empty clefs predominantly in the Kupffer cells, indicating cholesterol storage in the reticulo-endothelial cells. The acid lipase activity was less than 6% in all patients. In all suspected cases of Wolman's disease, a plain abdominal x-ray should be obtained to check for the typical pattern of adrenal calcification characteristic of the disease, especially in any young infant with failure to thrive and progressive hepatosplenomegaly
