Metastasis into a thyroid neoplasm-tumor-to-tumor metastasis-is exceedingly rare. We describe the 28th documented case of a tumor metastatic to a thyroid neoplasm and review the literature on tumor-to-tumor metastasis involving a thyroid neoplasm as recipient. All cases showed a recipient thyroid neoplasm with an abrupt transition to a morphologically distinct neoplasm. Metastasis into primary ...

Abstract Introduction/Objective Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare pancreatic tumor with low malignant potential composed poorly cohesive epithelial cells forming solid and structures. It develops almost exclusively (90%) in young females (mean age: 28 years, range: 7-79 years), while it rarely men 35 25-72 years). Methods/Case Report Herein we report an unusual pres...

Ependymoma constitute 5 % to 7 % of all primary CNS neoplasm. But their prevalence relative to other tumor type varies with patient age and presenting location. Ependymoma constitute approximately 1O % of intracranial neoplasm in pediatric population and up to 30 % of those encountered in children under 3 years of age. In spinal column, ependymoma constitute 60% of glial neoplasm, and opposed...

Primary sarcomas of the major blood vessels can be classified based on location in relationship to the wall or by histologic type. Angiosarcomas are malignant neoplasms that arise from the endothelial lining of the blood vessels; those arising in the intimal compartment of pulmonary artery are rare. We report a case of pulmonary artery angiosarcoma in a 36-year old female with pulmonary masses....

INTRODUCTION Vascular endothelial growth factors (VEGF) are members of a family of polypeptides encoded by a single gene containing eight exons and seven introns. Alternative splicing of exons 6 and 7 results in the production of four isoforms of the VEGF peptide. All four isoforms have the ability to increase vascularisation. The production of vascular endothelial growth factors (VEGF) is a ma...

Sclerosing angiomatoid nodular transformation(SANT) is benign neoplasm originating from vascular cells of the spleen. These tumors are rare between splenic lesions. In this paper,we present a SANT that arose in the upper pole of the spleen of a 61-years-old female. During the examination for anemia and diabetes mellitus,an splenic mass was found incidentally at the CT imaging. Open laparotomy w...

Intramuscular hemangiomas are rare benign vascular neoplasms. IMH accounts for less than 1% of all hemangiomas. These neoplasms commonly occur in trunk and extremities but are rare in head and neck region. The present case is a 17-year-old female patient, who presented with a painless, slowly enlarging mass in left sided upper neck for 4 years. Investigations were suggestive of vascular neoplas...

Background Right colectomy is the surgical treatment for malignant pathologies involving the intestinal tract between the ileocecal Bahuino valve and the colic hepatic flexure. Laparoscopic resection must respect the same oncological criteria as the open approach including: ‘’no-touch isolation technique’’, isolation and ligation of the vascular pedicles at the origin, oncological lymphadenecto...

Intraosseous hemangiomas are the rarest lesion of jaw bones (0.5–1%) occurs more commonly in vertebral column, skull bone, and rarely in mandible. Mostly occurs in the 2 nd decade of life with female: male predilection (2:1). Origin of hemangiomas is still not clear. World Health Organization considers it as a true benign neoplasm of vascular origin, and many authors believe it to be a hamartom...
