ABSTRACT
Metaplastic breast carcinoma is a rare subtype of invasive breast carcinoma. Metaplastic carcinoma with osseous differentiation is exceptionally uncommon. Because of the heterogenous microscopy of the lesion, various clinical and radiological features are observed, leading to diagnostic difficulty. Herein, we present a case of a 43-year-old female with a recurrent breast lump, who was clinically diagnosed as a phyllodes tumor. However, histopathological examination revealed metaplastic carcinoma with extensive osseous differentiation.

Adult type fibrosarcoma is very rare malignant soft tissue tumor. It usually arises in soft tissues of extremities, trunk, head and neck. Fibrosarcoma is essentially a diagnosis of exclusion from other spindle cell mesenchymal malignant neoplasm; by definition negative for epithelial, myogenous and neural markers on immunohistochemistry. To the best of our knowledge, very few cases have been reported in the literature. We here report a case of giant fibrosarcoma arising from anterior abdominal wall in a recurrent dermatofibrosarcoma proturbens and managed with surgical excision and reconstruction with meshplasty.
