Late seroma of the breast in association with COVID-19 infection: two case reports

Adverse reactions to cosmetic implants after COVID-19 vaccination: A literature review

BACKGROUND

As the world's population of people vaccinated with the COVID-19 vaccine increases, adverse reactions are increasingly being reported. There have been progressive reports of the effects of COVID-19 vaccination on cosmetic fillers or prostheses, but they have not been reviewed based on their clinical morphologic patterns. This article reviewed the progress of research on adverse reactions to cosmetic implants after COVID-19 vaccination.

METHODS

We researched the English-language literature up to October 15, 2022, using predefined keywords to identify relevant studies about adverse reactions to cosmetic implants after the COVID-19 vaccination, collecting patient characteristics, implant type, the time interval between vaccination and implantation or injection, time of onset, symptoms, treatments, and outcomes.

RESULTS

Among the adverse reactions to implants associated with COVID-19 vaccination, we distinguished between (1) injectable fillers and (2) surgical prosthetic implants. The most common adverse reactions were at the site of hyaluronic acid injection and breast prosthesis after Pfizer vaccination, mainly DIRs, and mainly manifested as edema, rash, fever, and capsular contracture. This paper also reported the possible causes, treatments of DIRs, and limitations of current studies.

CONCLUSIONS

In this article, we attempted to investigate and discuss all the adverse reactions of cosmetic implants related to COVID-19 vaccination in the current literature, to unmask these reactions and make a more accurate assessment of vaccine safety.

Delayed prosthetic seroma: a localized inflammatory response to COVID vaccination and infection?

We present a patient whom we believe developed a late abdominal mesh collection in response to COVID-19 mRNA vaccination booster and COVID-19 infection. A polypropylene mesh was placed during her right breast reconstruction operation 2 years ago where she underwent a right transverse abdominis rectus muscle (TRAM) free flap. She recovered uneventfully from this operation. This lady, though vaccinated, developed respiratory symptoms and tested positive for COVID-19 infection 3 days after her booster injection. She then noticed right-sided abdominal swelling 3 days after the onset of respiratory symptoms. She only presented 1 month later due to a 7-day history of pain at the site of abdominal swelling. A computed tomography scan confirmed the presence of a seroma, and she underwent ultrasound-guided percutaneous drainage. A COVID Antigen Rapid Test of the fluid returned positive, though the PCR swab returned negative. There have been no published reports of periprosthetic mesh seroma after COVID-19 vaccination or infection to date. We wanted to share our experience so that other surgeons may be aware of this potential presentation given the current ongoing pandemic. Level of evidence: Level V, risk/prognostic.

Late Seroma in Breast Implants: A Coronavirus Disease 2019 Phenomenon?

The coronavirus disease 2019 (COVID-19) pandemic has been challenging in all aspects of the medical field with new clinical presentations constantly arising. Plastic surgeons are not immune to this and need to be aware of their implications. There has been a recent report of late periprosthetic seroma (breast implant) as a clinical manifestation of COVID-19 infection. To our knowledge, this phenomenon has not been further reported. We present a 53-year-old immunocompromised lady who developed late seroma after COVID-19 infection. She eventually required explantation of the implant and is awaiting autologous reconstruction. It is likely that we will increasingly continue to see this phenomenon of implant complications as a result of COVID-19 infection and should be watchful, especially regarding potential immunocompromised patients.
