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 un-encapsulated mass in the right breast of a 60-year-old female. This case was diagnosed after exclusion of all po...

Backgrounds: Bleomycin (BLM) has been labeled with radioisotopes and widely used in therapy and diagnosis. In this study BLM was labeled with [62Zn] zinc chloride for oncologic PET studies. Materials and methods: The complex was obtained at the pH=2 in normal saline at 90 ° C in 60 min. Radio-TLC showed an overall radiochemical yield of 95-97% (radiochemical purity > 97%). Stability of complex ...

Case description: This report describes the simultaneous occurrence of fibrosarcoma and a urolith in the urinary bladder of a 12-year-old female terrier dog that was confirmed by pathology after excisional surgery. Clinical findings: The dog had some clinical signs such as frequent urination, hematuria and dysuria with an...

MRI showing 9.2 by 7.5 by 8.9 cm heterogeneous mass with vessels scattered throughout. Panel B. Biopsy of the mass showing spindle and plump cells, along with a vascular pattern similar to that of a hermangiopericytoma. Hypercalcemia of Malignancy in a Newborn with In...

Congenital-infantile fibrosarcoma is a rare entity with a five year survival rate of over 90%. Surgery is still the most common treatment modality with amputation often necessary. There have been reports supporting the use of neoadjuvant chemotherapy to debulk the tumour in an effort to facilitate limb sparing surgery. We report a case of a newborn who presented with a life threatening haemorrh...

Sclerosing epithelioid fibrosarcoma (SEF) is a rare variant of fibrosarcoma. It is a mesenchymal neoplasm composed of round to oval cells dispersed in a nestlike or cordlike distribution on a highly collagenous tissue background and is now recognized as a distinct clinical entity. In this report we discuss the presentation, diagnosis, and treatment of SEF. We focus on the unique histologic and ...

The underlying data demonstrates that fibroblast activation protein (FAP) paves the way for fibrosarcoma cells, which require the proteolysis of the extracellular matrix (ECM) and basement membranes to intravasate from implanted subcutaneous primary tumors into blood vessels, be transported to distant organs where they extravasate from the blood vessels, reattach and proliferate to metastases. ...
