Oncolytic effect of SARS-CoV-2 in a patient with mycosis fungoides: A case report.

The most common variant of cutaneous T-cell lymphomas (CTCL) is mycosis fungoides (MF). Patients with MF often experience a chronic course of disease. The spontaneous regression (SR) of MF is rare, and the factors that predict SR have not been recognized yet. Here, we are reporting a case of persistent MF who had prominent remission after COVID-19. This case report supports the possible antineoplastic effect of SARS-CoV-2. Understanding the underlying etiology of such effect can result in development of new target therapies for MF.
