ReviewGoing viral: A brief history of Chilblain-like skin lesions ("COVID toes") amidst the COVID-19 pandemic.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of the COVID-19 global pandemic, is notable for an expanding list of atypical manifestations including but not limited to coagulopathies, renal dysfunction, cardiac injury and a multisystem inflammatory syndrome in children. In addition, SARS-CoV-2 has been purportedly linked to multiple cutaneous manifestations, among them chilblain-like skin lesions, also known as "COVID toes." Driven in large part by social media, dermatologists around the world reported a dramatic increase in the frequency of chilblain-like diagnoses early in the COVID-19 pandemic, often in members of the same family. This phenomenon has been captured in a rapidly expanding medical literature. ⋯ Evidence of SARS-CoV-2 infection is not consistently found when these patients are evaluated by polymerase chain reaction. A robust antiviral immune response in young patients that induces microangiopathic changes has been posited as a mechanism. Herein we review the rapid evolution of the literature regarding chilblain-like skin lesions early in the COVID-19 global pandemic.

Multicenter StudyData of Italian Cancer Centers from two regions with high incidence of SARS CoV-2 infection provide evidence for the successful management of patients with locally advanced and metastatic melanoma treated with immunotherapy in the era of COVID-19.
Patients with cancer are presumed to have a higher risk to contract SARS-CoV-2 infection, because of their immunosuppressed status. The impact and course of COVID-19 infection in cancer patients receiving immunotherapy remains unknown. ⋯ The incidence of symptomatic COVID-19 infection observed in our cohort of patients with advanced malignant melanoma treated with immunotherapy appears meaningfully lower as compared with that reported in the overall population in Italy as well as in patients affected by solid tumors. We conclude that in patients with locally advanced and metastatic melanoma, immunotherapy can be safely continued without delay in the majority of cases, reserving precautionary delay only for the most frail patients.

Review Meta AnalysisFDA analyses of survival in older adults with metastatic non-small cell lung cancer in controlled trials of PD-1/PD-L1 blocking antibodies.
Among patients with newly diagnosed non-small cell lung cancer (NSCLC), approximately 70% occur in those above 65 years of age and more than half are metastatic or locally advanced NSCLC. ⋯ Patients 65 and older with advanced and metastatic NSCLC, including those ≥75 years, seem to derive similar survival benefits from treatment with PD-1/PD-L1 blocking antibodies as patients <65 years of age. Patients 75 and older enrolled on these trials appear to tolerate PD-1/PD-L1 blocking antibodies and have a lower incidence of grade 3 or 4 treatment-emergent adverse events compared to the subgroup of patients <65 years of age.

Optimal management of patients with locally advanced non-small cell lung cancer remains challenging in the context of this heterogeneous disease. Despite aggressive therapeutic approaches, survival benefits are still unsatisfactory for what might be viewed as a localized malignancy. ⋯ Nevertheless, several features of therapy remain controversial and lack formal prospective data. Traditional cytotoxic chemoradiation therapy may have reached a plateau and future perspectives opting to integrate molecularly targeted agents and immunotherapy might be the way to improve outcomes in this disease subset.
