[Association of pulmonary carcinoma and ductal breast cancer].

Multiple primary cancers are relatively rare. The association between lung and breast cancer is exceptional and requires genetic research and predisposing factors. We report the case of a female patient of 43years, hospitalized for atelectasis of the left lung with breast lumps. Bronchial biopsies have concluded a primary lung adenocarcinoma. Breast biopsy objectified ductal invasive breast cancer. The treatment was a palliative chemotherapy. The evolution is marked by the early death of the patient. Although the association of multiple cancers is rare, their discovery requires a particular treatment regimen depends on the staging of each cancer.
