Core Tip
Core tip: We present the second case of lung adenocarcinoma with metastasis to the breast in a patient under 30 years of age. This is a rare entity in oncology and even more so in this age group. There have only been 63 reported cases of breast metastasis from lung adenocarcinoma over the last eighteen years. A clear correlation between the side of primary lung cancer and the side of breast metastasis can be identified. Due to the infrequency of this phenomenon, the diagnosis may cause a significant dilemma. Nevertheless, immunohistochemistry plays a key role in the final diagnosis.
