Which symptom is NOT typical of tumour lysis syndrome?

• A. Weakness, nausea, vomiting, diarrhoea, shortness of breath, irregular heart rate
• B. Skin rash and itching
• C. Joint pain and stiffness
• D. Seizures

Answer: (D)

Tumor lysis syndrome happens when rapid tumor cell breakdown floods the blood with potassium, phosphate, and uric acid while calcium drops. This creates a pattern of symptoms tied to those metabolic changes: weakness, nausea, vomiting, diarrhea, shortness of breath, and irregular heart rhythms from electrolyte imbalances and kidney strain. Seizures aren’t a typical feature you’d expect to see as a hallmark of TLS; they can occur only if the electrolyte disturbances become extremely severe, but they’re not a common presenting symptom. That’s why this symptom is identified as not typical. Skin rash or itching and joint pain aren’t standard TLS signs either, but seizures stand out as not fitting the usual TLS presentation.
