What is a defining symptom of sialidosis?

• A. Hepatosplenomegaly
• B. Coarse facial features
• C. Cherry-red macules
• D. Corneal clouding

Answer: (C)

Sialidosis is a lysosomal storage disorder characterized primarily by the accumulation of sialic acid. One of the hallmark features of sialidosis is the presence of cherry-red macules, which are bright red spots typically found on the retina. This feature is particularly significant in differentiating sialidosis from other lysosomal storage diseases. As the disease progresses, individuals may experience neurological deterioration and skeletal abnormalities, but the cherry-red macules can serve as an important diagnostic indicator. The unique appearance of these macules can help in the visual diagnosis during a clinical examination, providing crucial evidence of the disorder. The other symptoms associated with this condition, while they may appear in other storage disorders, are not definitive for sialidosis, thereby emphasizing the importance of the presence of cherry-red macules in establishing the diagnosis.
