Neurology® Podcast Paraneoplastic Neurologic Syndromes Associated With Merkel Cell Carcinoma
Jan 9, 2025
In this talk, Nicolás Lundahl Ciano-Petersen, a researcher with expertise in paraneoplastic neurological syndromes, shares fascinating insights on the rare connection between these syndromes and Merkel cell carcinoma. He discusses the intriguing clinical profiles of patients, including symptoms like Lambert-Eaton myasthenic syndrome. Lundahl also highlights the potential for spontaneous tumor regression and emphasizes the need for multidisciplinary approaches in diagnosis and treatment, given the complexities surrounding these disorders.

Rare Syndromes
- Paraneoplastic neurologic syndromes with Merkel cell carcinoma are rare, with only about 47 reported cases.
- These syndromes present a heterogeneous clinical and immunological profile.
Key Syndromes
- Key neurological syndromes linked to Merkel cell carcinoma include Lambert-Eaton myasthenic syndrome (LEMS), cerebellar degeneration, and encephalomyelitis.
- Further research is needed to explore the connection between these syndromes and the tumor.
Merkel Cell Carcinoma Diagnosis
- Consider Merkel cell carcinoma in elderly, Caucasian patients with rapidly growing, painless, pink or violet skin masses in sun-exposed areas.
- Immunosuppression and Merkel cell polyomavirus are significant risk factors.
