Multiple maxillary periodontal abscesses as a manifestation of post-coronavirus disease 2019 mucormycosis: a case report

J Med Case Rep. 2023 Mar 3;17(1):74. doi: 10.1186/s13256-023-03792-6.


Background: Coronavirus disease 2019 makes patients more susceptible to superinfection of fungal disease as a consequence of immunological system impairment. Mucormycosis is a fungal infection that is rare but has a high mortality rate and mostly affects patients with poorly controlled diabetes mellitus or those receiving corticosteroids.

Case presentation: Here, we present a case of post-coronavirus disease 2019 mucormycosis in a 37-year-old Persian male presenting with multiple periodontal abscess with purulent discharge and necrosis of maxillary bone (without oroantral communication). Surgical debridement following antifungal therapy was the treatment of choice.

Conclusion: Early diagnosis and immediate referral are the cornerstone of comprehensive treatment.

Keywords: COVID-19; Mucormycosis; Periodontal abscess; Post-COVID mucormycosis.
