Bilateral late hematomas after breast augmentation mimicking anaplastic large cell lymphoma: A case report.
[RATIONALE] Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is rare, but its incidence has recently increased. It is characterized by a sudden onset of seroma collection after implantation of textured breast implants. Ho…
