Our study suggests that patients who suffer from PCLs may represent a risk group for potential life-threatening complications in case of infection with SARS-CoV-2.Risk factors for infections in PCL patients include lymphopenia, chronic organ failure (renal, cardiac or respiratory), Sezary syndrome, other comorbidities (e.g. diabetes and hypertension), aggressive immunosuppressive treatment, advanced/aggressive disease and older age leading to severe COVID-19 symptoms. 5 Several guidelines for the management and the treatment of cutaneous lymphoma during the COVID-19 pandemic have been recently established by the United States CL Consortium and the EORTC CLTF. 6,7 In conclusion, physicians should consider that PCL patients are at risk for severe COVID-19; therefore, reinforced preventive measures and prioritization in vaccination strategies are required.
Onychomatricoma is a rare benign tumor of the nail matrix, characterized by finger-like projections that invade the nail plate. The fingernails of Caucasian women are most commonly affected. Because this tumor can easily mimic other more prevalent ungual diseases, it is crucial to be acquainted with its characteristic clinical and histopathologic features. The authors present a case of a 40-year-old man with an onychomatrichoma in the fourth left toenail, which was initially misdiagnosed and treated as onychomycosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
