Although coronavirus disease 2019 (COVID-19) primarily manifests pulmonary symptoms, providers are recognizing extrapulmonary symptoms including cutaneous manifestations. Cutaneous manifestations in COVID-19 patients include acroischemic, chilblain-like eruption, petechiae and purpura, vesicles, urticaria, and erythematous maculopapules. 1 Herpes zoster (HZ) is caused by the varicella-zoster virus, which reactivates and spreads from the dorsal root ganglia to its respective dermatome. Patients at risk of HZ include elders and immunocompromised hosts. Although COVID-19 is known to affect the immune system and may increase the risk of HZ, limited reports confirm an association between HZ and COVID-19. 2,3 Here, we present a 70-year-old COVID-19 patient complicated by HZ.
Kikuchi-Fujimoto disease (KFD) is a rare, benign, self-limiting necrotizing lymphadenitis of unknown etiology. The disease can affect people of all ages and of any sex and ethnicity. Tissue biopsy is needed for accurate diagnosis. The condition commonly masquerades as more sinister conditions such as malignancy and rheumatologic disorders, but has a much better prognosis. Treatment is generally supportive but patients may require corticosteroids with eventual spontaneous resolution. We discuss a case of KFD in a 34-year-old male and highlight the need for prompt and accurate diagnosis.
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.
