Breast implant-associated anaplastic large-cell lymphoma: A series of two case reports diagnosed by cytopathology.

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare T-cell lymphoma with a good prognosis. It occurs in association with textured breast implants. Its most common presentation is a late-onset peri-implant effusion. We present two cases of BIA-ALCL diagnosed by cytopathological examination of the fluid collection and describe the cytopathologic findings. Both patients were disease free after implant removal. This report highlights the contribution of the cytopathologic analysis to early diagnosis and definite treatment of BIA-ALCL.
