An atypical cause of rapidly progressing breast lump with abscess formation: Pure squamous cell carcinoma of the breast

J Cancer Res Ther. 2015 Oct-Dec;11(4):1023. doi: 10.4103/0973-1482.147735.


Squamous cell carcinoma (SCC) is a rare type of breast malignancy and little is known about long-term outcome. In the present report, the clinical features, histopathologic findings and postoperative course of a patient with squamous cell carcinoma are described. We have treated a 47-years-old woman who admitted for right breast mass without any discharge, bleeding and pain. The tumor was, 3 × 2 × 1.5 cm in size with central abscess formation. The result of surgical biopsy revealed large cell keratinizing type of SCC. The metastatic work-up studies ruled out any other probable sources of primary tumor. The patient was performed modified radical mastectomy and axillary dissection and received two cycles of chemotherapy. Squamous cell carcinoma of the breast (SCCB) is a rare entity and should be considered in patients with rapidly progressing breast mass. It should also be considered in breast lesions with abscess formation. The initial therapeutic approach should be surgical excision after histopathological diagnosis.
