Our results indicate that, from the oncological standpoint, patients with prior augmentation can undergo lumpectomy with equivalent tumor margins and re-excision rates. To the best of our knowledge, this is the first reported comparative study between these 2 groups.

Implant-sparing mastectomy with delayed implant exchange in patients with preexisting subpectoral implants is safe and has fewer complications compared to tissue expander placement. There was no difference noted in the final volume of implant placed, time interval for final implant placement, or tumor margins.

Serotonin syndrome (SS), a potentially life-threatening condition, typically occurs due to polypharmacy and interaction with multiple serotonergic agents. The case presented here is based on a serotonin syndrome (SS) diagnosis, precipitated by newly prescribed tramadol in conjunction with previously prescribed serotonergic medications. A 79-year-old woman receiving combined citalopram and trazodone for major depressive disorder alongside oxycodone for chronic pain developed generalized weakness, tremors, altered mentation, episodic auditory and visual hallucinations, fever, tachypnea, tachycardia, and diaphoresis a few days after tramadol was prescribed for pain. On clinical examination to medication reconciliation, and ruling out other causes of altered mental status, it became evident that the addition of tramadol had resulted in acute serotonin toxicity. SS is important to recognize because many healthcare providers encounter it during their careers. This diagnosis is essential to include in the differential diagnosis, especially when a medication not often associated with serotonin, like opiates, is the culprit.

Patients with prior breast augmentation undergoing mastectomy have higher complication rates compared with lumpectomy even after adjusting for tumor stage. There appears to be no increased oncologic risk associated with either procedure given our current follow-up. Understanding these operative risks may help in patients' decision-making process with regards to type of oncologic surgery.
