Case in brief

A 68-year-old man presented with synchronous squamous cell carcinomas of the esophagus and mandibular gingiva. He received pembrolizumab combined with cisplatin and 5-fluorouracil, leading to a clinical complete response in the gingival and metastatic lesions, and a near-complete response in the esophageal tumor. The treatment was well-tolerated, allowing the patient to regain oral intake and body weight.

Diagnostic / clinical pearl

This case highlights the potential efficacy of PD-1 blockade in patients with multiple primary cancers, despite limited evidence in this population.
