title: [Cholesterol ester storage disease: a rare disease or a rare diagnosis?].
abstract: We report the case of a 13-year-old boy with a longstanding history of unspecific hepatomegaly. The morphological investigations were diagnostic of a cholesterol ester storage disease (CESD), a rare autosomal recessive inherited disease with deficient activity of lysosomal acid lipase (LAL). The combination of hepatomegaly with accumulation of macrophages and ultrastructural evidence of lysosomal lipid storage are groundbreaking for the diagnosis. The probability of a underdiagnosis or false disease classification, for example as nonalcoholic steatohepatitis (NASH), is high, particularly with regard to genetic data which indicate a higher incidence of the disease.
