We present a case of a 34-year-old female who had a rapidly enlarging right breast mass. Biopsy results were consistent with a neuroblastic neoplasm of the breast. Neoadjuvant chemotherapy for a neuroblastoma was performed followed by a modified radical mastectomy was performed. Final pathology revealed small foci of poorly differentiated carcinoma randomly distributed within extensive areas of...

While carcinoma of breast is common condition, stromal sarcomas are rare tumors of breast, amongst which fibrosarcoma accounts for 16% of cases. Only a few case reports are available in the international literature. We report a case of fibrosarcoma of breast, which presented as an unencapsulated mass in the right breast of a 60-year-old female. This case was diagnosed after exclusion of all pos...

INTRODUCTION Metaplastic breast carcinoma (MBC) is a rare type of breast cancer. Osseous differentiation is a very rare subtype. Reporting this kind of case is important because its clinical course and line of management are poorly mentioned in the literatures. We present a very rare case of MBC with osseous differentiation. A 48-year-old female presented with painless hard mass of the left bre...

UNLABELLED Mammary sarcoma is extremely rare and the diagnosis is established only after metaplastic carcinomas and malignant phyllodes tumours are excluded. A rare case of not otherwise specified-type sarcoma with CD10 expression in the left breast in a 45-year-old female was presented. It was a high-grade tumour composed of spindle cells histologically. The immunohistochemical results showed ...

Metaplastic breast carcinoma (MBC) is an uncommon malignancy characterized by the co-existence of two or more cellular types, commonly a mixture of epithelial and mesenchymal components. A case of a female patient aged 46 years with MBC (carcinosarcoma) is presented, including mammographic, ultrasonic, gross examination, and pathological findings. After undergoing modified radical mastectomy of...

A 40-year-old woman noted a large mass in her right breast. A diagnostic mammogram and ultrasound confirmed a 3.4-cm mass with associated microcalcifications. Axillary ultrasound showed a prominent lymph node in the right axilla. A core needle biopsy of the breast mass was positive for a high-grade metaplastic carcinoma with predominantly squamous features (Figure, panel A). The lymph node biop...

Mammary sarcomas are uncommon tumors. Of these pure chondrosarcoma without any other area of epithelial or mesenchymal differentiation feature as even rarer. This excludes tumors like malignant cystosarcoma phyllodes and metaplastic carcinoma where malignant cartilaginous areas may be present. Further primary chondrosarcoma arises from breast stroma and not from underlying bone or cartilage. On...
