Invasive stage III breast implant-associated anaplastic large cell lymphoma successfully treated with incomplete resection.

A woman with history of bilateral breast augmentation 15 years prior presented with right breast swelling, peri-implant effusion and a palpable inferomedial mass. Effusion aspiration demonstrated pleiomorphic cells consistent with breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). Further diagnostic studies confirmed stage III disease with a 4.7 cm right breast mass and fluorodeoxyglucose uptake in an internal mammary chain lymph node. The patient underwent surgery with incomplete resection due to invasion of the chest wall followed by chemotherapy and radiation therapy. BIA-ALCL typically presents as an indolent effusion, however advanced disease carries a worse prognosis. This case highlights successful treatment without recurrence past the one-year mark as well as the need for multidisciplinary management when dealing with advanced disease.
