Core Tip

Core Tip: Paraneoplastic peripheral neuropathy is more common in patients with small cell lung cancer (SCLC), but the exact role of peripheral nerve symptoms and electromyography (EMG) in SCLC is still the subject of debate and research. At present, there are few reports of SCLC with peripheral nerve injury as the first symptom and EMG results. This article reports two cases of SCLC with limb numbness and weakness as the initial symptoms, highlighting the potential role of paraneoplastic peripheral nerve status and EMG in SCLC screening and the possible clinical correlation between them.
