[Squamous cell carcinoma of the breast--case report].
A rare case of squamous cell carcinoma of the breast is presented. A 50 year-old female patient suffered from a painful tumor of the right breast 8 years prior to death. The histology of the resected mammary tumour revealed squamous cell carcinoma with an adenocarcinomatous feature in the minority. Malignancy developed in the left lung 5 years after the surgery and formed a huge mass including the pectoral muscle and esophagus. At autopsy, metastases were found in the pericardial sac and liver. Histologically, a prominent well-differentiated squamous cell carcinoma element was identified in the lung, whereas an adenocarcinomatous figure was predominant in the other sites.
