A review of malignant Brenner tumors reported in the literature reveals widespread confusion over diagnosis and many cases that are not valid. The reasons for this are discussed. Newly defined diagnostic criteria are suggested and illustrated by a case report.

Malignant rhabdoid tumor (MRT) was originally described by Haas et al. in 1981 as an aggressive childhood renal tumor that was believed to represent a rhabdomyosarcomatous variant of Wilms tumor (or nephroblastoma). MRT was later recognized as a separate entity, and extrarenal rhabdoid tumors occurring in various sites such as the brain (atypical ...

Malignant tumors of the eyelid
Plastic and Reconstructive Surgery, 1972A retrospective analysis was conducted of all malignant tumors of the eyelids and canthi at Pondville Hospital, Norfolk, Massachusetts from 1929 through April 1971 involving 296 patients with 334 lesions.

Mayo Clinic Proceedings, 1993
Malignant tracheal tumors are uncommon and present diagnostic and therapeutic challenges. The most frequently diagnosed types of such tumors are squamous cell and adenoid cystic carcinomas. These tumors usually manifest with the obstructive symptom of wheezing; thus, they are often misdiagnosed as asthma.

Pituitary malignancies are rare. The definition of pituitary malignancy is still subject to debate. Three types of malignancy with the description of clinical course and complete autopsy were presented; i) true carcinosarcoma, ii) ectopic sphenoid invasive tumor, and iii) post-irradiation sarcoma.

Human Pathology, 1994
Two patients, 14 and 46 years of age, presented with diffuse, rapidly growing intracerebral tumors leading to death 6 1/2 and 9 1/2 months, respectively, after diagnosis. Histological examination showed sheets of moderate-sized tumor cells with clear cytoplasm and central nuclei interrupted by delicate arciform vasculature, an appearance distinctly ...

Angiogenesis in malignant tumors.
Acta medica Croatica : casopis Hravatske akademije medicinskih znanosti, 2001Angiogenesis is the formation of new blood vessels from the existing vascular network. It is a complex, multi-step process involving extracellular matrix remodeling, endothelial cell migration and proliferation, capillary differentiation, and anastomoses. Angiogenesis is crucial for tumor progression and metastasizing. Intratumor microvessel density is
