Immune checkpoint inhibitors are a novel group of immunotherapeutic agents for the treatment of cancer. Immune-related adverse events, including neurological symptoms, have been associated with these agents. We present the case of an adolescent with refractory Hodgkin lymphoma treated with nivolumab, a PD1 inhibitor, who developed Hashimoto thyroiditis, posterior reversible encephalopathy syndrome causing seizures, as well as urinary retention, truncal/appendicular spasticity, dysphagia, and a progressive encephalopathy that was clinically consistent with a diagnosis of progressive encephalopathy with rigidity and myoclonus, a stiff-person-syndrome spectrum disorder. He showed response and ultimately full recovery to a combination of intravenous steroids, intravenous immunoglobulin, and plasma exchange. To our knowledge, this is the first documented report of an immune-related neurological reaction to nivolumab in an adolescent patient and expands the spectrum of known nivolumab-associated toxicities.

Primary malignant melanoma of the esophagus is rare, accounting for less than 0.1-0.2% of all esophageal malignancies. It is associated with a poor outcome due to late detection and high metastatic potential. Here, we report a case of esophageal cancer, which was initially diagnosed as an adenocarcinoma and finally was confirmed as a primary malignant melanoma. This 75-year-old Caucasian male had a history of dysphagia and recent lingering abdominal pain. First biopsy showed a poorly-differentiated adenocarcinoma. He was then treated with neoadjuvant radiochemotherapy. Biopsies were repeated because of an incomplete tumor response, evaluated by endoscopic and imaging studies. The final diagnosis was a malignant melanoma. The patient has been treated with immune-checkpoint inhibitor, nivolumab, an anti-PD1 antibody.
