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

Abstract

The SARS-CoV-2 pandemic is giving rise to a wide range of clinical manifestations, which can affect all organs and systems. Due to the enormous and constantly growing number of infected people, even the rarest complications will be observed in a very high number of patients. Late periprosthetic seroma of the breast has gained importance since the description of Breast Implant Associated Anaplastic Large Cell Lymphoma (BIA-ALCL), but this entity is not the only cause. Among the causes of non-BIA-ALCL late seroma, we can include those of mechanical origin and those of non-mechanical origin. Within the latter, the common denominator is the triggering of an aberrant immune reaction that generates an inflammatory exudate from the periprosthetic capsule that gives rise to the seroma. We present two cases of late breast seroma as a manifestation of SARS-CoV-2 infection.Level of evidence: Level V, diagnostic study.
