Abstract
Gaucher disease (GD) type 1 is the most common lysosomal storage disorder due to beta glucocerebrosidase deficiency leading to an abnormal accumulation of its substrate, glucocerebroside, in the mononuclear phagocyte system. The disease presentation is usually characterized by signs and symptoms related to hypersplenism, such as splenomegaly, anaemia, thrombocytopenia and leucopenia. Skeletal disease may occur later for the infiltration of bone marrow by macrophages infiltration and bone resorption: bone involvement may be heterogeneously manifested by symptoms ranging from bone crisis to avascular necrosis, osteoporosis and defect in remodeling of long bones. Herein, we report a patient in whom the osteoarticular involvement has been the only symptom of the disease stressing that this unusual presentation of GD has prompted a wide differential diagnosis with more common forms of coxitis.

Gaucher disease (GD) type 1 is the most common lysosomal storage disorder due to beta glucocerebrosidase deficiency leading to an abnormal accumulation of its substrate, glucocerebroside, in the mononuclear phagocyte system
GD is a lysosomal storage disorder caused by deficiency of the enzyme beta glucocerebrosidase, leading to accumulation of glucocerebroside within tissue macrophages in multiple organs
GD has typically been described as an adult disorder affecting mainly Ashkenazi Jews, 49% of GD type I cases are diagnosed before years of age and an additional 17% between and 20 years of age [1]
