Letterer-Siwe disease is a disturbance of
1) Protein metabolism
2) Lipid metabolism
3) Mucopolysaccharide metabolism
4) Carbohydrate metabolism
Oral Pathology
Answer: 2
Letterer-Siwe disease is a type of Langerhans cell histiocytosis that is associated with disturbances in lipid metabolism.
Letterer-Siwe disease is a form of Langerhans cell
histiocytosis (LCH), which is characterized by the proliferation of
Langerhans cells, a type of dendritic cell involved in immune response. This
disease primarily affects children and can present with a variety of symptoms,
including:
Bone Lesions: Osteolytic bone lesions, particularly in
the skull, vertebrae, and long bones.
Skin Rash: Erythematous lesions or seborrheic
dermatitis-like rashes.
Hematological Abnormalities: Anemia, thrombocytopenia,
and leukopenia may occur.
Organ Involvement: It can affect multiple organs,
including the liver, spleen, and lungs.
Metabolic Disturbance:
Lipid Metabolism: Letterer-Siwe disease is associated
with disturbances in lipid metabolism, particularly due to the accumulation
of lipids in the affected tissues. The Langerhans cells in this condition
can exhibit abnormal lipid storage, which is a hallmark of the disease.
