Summary: Anaplastic large cell lymphoma of the breast is a rare malignancy associated with prosthetic breast implants. We present a case of a woman with no prior history of breast implants who developed anaplastic lymphoma kinase-1 negative anaplastic large cell lymphoma on a background of a previous benign cyst aspiration.
