Post-COVID steroid induced avascular necrosis of the jaw: Emerging challenge in India.

ABSTRACT

The COVID-19 pandemic continues to evolve and spread with new variants of SARS-CoV-2 across the globe, as well as bring to clinical attention several post-COVID conditions. We report a post-COVID condition observed at our tertiary care center spontaneous de novo development of steroid induced avascular necrosis in patients who have recently recovered from COVID-19 following high dose steroid usage in a short span of time. Pre-COVID published literature indicates that these lesions were seen very rarely in the jaws and were related to long-term usage of steroids and recent tooth extraction. They were considered under the broad spectrum of medication-related osteonecrosis of the jaws. Present authors believe that the post-COVID-19 steroid-induced avascular necrosis of the jaws is a distinct new entity. It is analogous to the avascular necrosis noticed in the femoral head of individuals recuperating from COVID-19, a condition conventionally known to be strongly associated with steroid therapy. Rapid progression, associated morbidity and mortality, and its possible differential diagnosis require pathologists to be vigilant regarding the chance encounter of such cases in jaws. Further reporting of such cases is required to gain additional insight into its features.
