Diagnostic and therapeutic pitfalls with primary breast sarcoma: A case report and review of the litterature

Abstract

Primary breast sarcomas are rare and aggressive tumours that represent less than 1% of breast neoplasms. An 18-year-old female presented with a right breast mass, histology of which revealed a benign phyllodes tumour. After a multidisciplinary consultation, a right mammectomy with axillary curage was indicated. Histopathological and immunohistochemical analysis of the operative specimen were in favour of a grade 2 primary sarcoma with cutaneous and axillary extension. The post-mastectomy course was marked by tumour recurrence. Diagnostic and therapeutic difficulties are related to the young age, clinical presentation and histopathology of this entity.
