title: Primary chondrosarcoma of breast--cytology with histopathological correlation: a rare case report with review of literature.
abstract: Malignant mesenchymal tumors of the breast other than angiosarcoma are extremely rare and comprise <0.5% of breast tumors. Primary chondrosarcoma of the breast is an extremely rare entity and only 10 cases are reported as single case reports in literature until date. A diagnosis of primary mammary sarcoma can be established only after excluding metaplastic carcinomas and malignant phyllodes by extensive sampling for evidence of in situ or invasive carcinoma. Here, we report a primary chondrosarcoma of breast in a 55-year-old lady diagnosed precisely on fine-needle aspiration cytology and confirmed by histopathological examination after total mastectomy. We emphasize on diagnostic difficulties encountered in cytology smears and discuss differential diagnoses.
