This study presents two siblings with cholesterol ester storage disease, highlighting key diagnostic findings. Microcrystallized cholesterol in liver cells confirmed the diagnosis, with differing disease severity between the siblings.

Area of Science:

Biochemistry
Genetics
Pediatric Medicine

Background:

Cholesterol ester storage disease (CESD) is a rare inherited metabolic disorder.
CESD is characterized by the accumulation of cholesterol esters in various tissues, particularly the liver.
Genetic mutations affecting cholesterol metabolism lead to CESD.

Observation:

Two siblings, a male and a female, diagnosed with CESD were studied.
Clinical, biochemical, and histopathological features were analyzed.
Hepatic ultrastructural examination revealed microcrystallized cholesterol within Von Kupffer's cells.

Findings:

Microcrystallized cholesterol in hepatic Von Kupffer's cells served as a definitive diagnostic marker.
Significant differences in clinical presentation and disease progression were observed between the siblings.

The male sibling experienced more severe functional impairment, necessitating liver transplantation.

Implications:

Early and accurate diagnosis of CESD is crucial for timely intervention.
Understanding the variable clinical expressivity of CESD can guide patient management.
Liver transplantation may be a viable therapeutic option for severe CESD cases.
