Delayed Metastatic Polypoid Nodular Melanoma Diagnosis During COVID-19 Pandemic, Successful Treatment With Surgery and Nivolumab

Patients with polypoid (pedunculated) melanoma have the poorest 5-year survival rate compared with all other variants of nodular melanoma, presenting with increased thickness, incidence of metastasis, and rates of ulceration. There are few published reports regarding the pathogenesis and treatment of polypoid melanomas. We report the successful treatment of a rapidly developing red nodular polypoid melanoma with metastasis using surgery followed by anti-PD-1 antibody nivolumab in a SARS-CoV-2-positive patient who delayed seeking care due to the COVID-19 pandemic.
