Summary

We present a case of carcinoma en cuirasse as a presentation of advanced lobular breast carcinoma. On further investigation, she was found to have metastasis to her liver and bone. We report this case to highlight the phenomenon of cutaneous metastasis. It is important to consider this diagnosis as an initial manifestation of breast cancer, but rarely, it can also be associated with other adenocarcinomas, for example, carcinoma of lung, kidney or gastrointestinal tract.
