title: [Primary squamous cell carcinoma of the breast - a case report].
abstract: Breast cancer is the most common malignant tumor among women in Poland. According to the Center of Oncology (The National Cancer Registry) in 2010 in our country 15,784 new cases have been noted. Since 1970s worldwide growth of new cases of breast cancer have been reported. Among the well-known histological types of breast tumors, small percentage - only 0.1% - include squamous cell component.
  
  
  METHODS
  A 69-year-old female met her doctor because of the right breast tumor. After two months of observation, in the last two weeks before the visit, the tumor started to grow very rapidly. As the diagnosis from fine needle aspiration biopsy (squamous cell carcinoma) was very rare for this location, and considering the other clinical symptoms the woman reported, it was suspected to be metastatic. Finally, as the other origins of the primary tumor have been declined and as the patient's condition begun to worsen very rapidly, the urgent treatment: mastectomy (toilet mastectomy) and adjuvant chemotherapy afterward, according to the pathological report were performed.
  
  
  CONCLUSIONS
  Rare histological types of the breast cancer use to suggest a metastatic origin or behave as tumors with highly malignant histological grade.
