To the Editor:

During the ongoing COVID‐19 vaccination campaign, there have been various cutaneous reactions reported in both clinical trial and post‐trial data. , , We recently encountered a remarkable clinical case of a cutaneous reaction after COVID‐19 vaccination associated with dermal filler. Rare cases of cutaneous reaction associated with dermal fillers and COVID‐19 vaccination have been reported and prompt to question why this reaction occurs and how to appropriately respond?

A 26‐year‐old woman experienced sudden chin enlargement approximately 24 h after receiving her second dose of Moderna COVID‐19 vaccine (Figure 1A). The patient also reported slurred speech, paresthesia of the lower face, headache, and malaise. There were no symptoms or signs related to angioedema. The patient received her first dose of Moderna COVID‐19 vaccine exactly 29 days prior without complications. Past medical history was significant for Juvederm Volux injection to the chin and jaw 3 years prior. The patient denied prior allergy to vaccines, drugs, and food. Otherwise, the patient's past medical history and surgical history were entirely unremarkable. The patient's swelling and symptoms gradually resolved over a 48‐hour period (Figure 1B).

This brief clinical vignette showcases the localized dramatic and pronounced skin swelling associated with the Moderna COVID‐19 vaccine and dermal fillers. This reaction is thought to represent a delayed‐type hypersensitivity reaction to an immunologic trigger following COVID‐19 vaccination. Theoretically, hyaluronic acid‐based fillers could act as adjuvants that enhance an antigen‐specific immune response, particularly in individuals with risk factors of previous vaccine reaction, allergy, or urticaria. New hyaluronic acid‐based fillers can persist in facial structures from 2–5 years and have been suggested as a potential nidus for such a delayed inflammatory reaction (DIR), which has been reported to last between approximately 24 h and 3 weeks in different regions of the face. Consistent with previously rare, documented cases, we do not have histologic findings to report as a skin biopsy was not performed due to the transient and aesthetically sensitive nature of this cutaneous reaction. Our case documents that this rare reaction can occur up to 3 years after dermal filler injection.

CONCLUSION

Adverse cutaneous reaction associated with dermal fillers and the Moderna COVID‐19 vaccine has rarely been reported. , , This reaction can be striking and worrisome for patients and is important for physicians to consider this in the differential diagnosis for patients with facial swelling and a history of dermal filler treatment and COVID‐19 vaccination. Previous cases of facial swelling were successfully managed using short courses of oral steroids; however, our patient's mild symptoms resolved without treatment. Ultimately, the benefits of COVID‐19 vaccination greatly outweigh the minute risk of cutaneous delayed inflammatory reaction; however, all physicians should remain aware of this potential reaction and provide appropriate counselling to high‐risk patients.
