Primary, as well as secondary, lymphomas of the breast are rare diseases and might, in some cases, be misdiagnosed as breast cancer on routine hematoxylin/eosin stainings. We report a case of an anaplastic large cell lymphoma in a 72-year-old woman with a history of breast cancer treated with breast-ablative surgery and a subsequent silicon implant 32 years ago. Clinically, she presented with an ulceration of the skin, which had developed within a few months. On conventional histology, the tumor cells were mimicking poorly differentiated invasive ductal carcinoma with a prominent leukocytic infiltrate. The immunoprofile of the tumor showed negativity for cytokeratins and led to the diagnosis of a CD30-positive anaplastic large cell lymphoma.
