Note: Tumor staging is separated by TNM classification (International Classification of Diseases, ICD). TNM classifications for carcinomas of the gallbladder, extrahepatic bile ducts and the ampulla of Vater. The histopathological classification of biliary tract carcinoma follows WHO classification: adenocarcinoma, adenosquamous carcinoma, squamous cell carcinoma, small cell carcinoma, adenoend...

The diagnosis of endometrial carcinoma requires histopathological confirmation. This diagnosis is made according to the WHO pathological classification. About 80% of endometrial carcinomas are of endometrioid type. Serous (5–10%), clear cell (1–5%), mucinous, mixed, squamous cell, transitional cell and undifferentiated carcinomas are other established subtypes. Endometrial carcinosarcoma is now...

We report a case of carcinosarcoma of the minor salivary glands of the left palatine tonsil, an especially rare location. Imaging characteristics assessed at CT, MR imaging, and angiography are presented. In addition, we describe our experience with preoperative therapeutic endovascular embolization of this hypervascular tumor.

Carcinosarcomas are rare biphasic malignant neoplasms with an epithelial and a spindle cell component. We present a 62-year-old man with a history of noticeably abdominal distension, proved by surgery to be caused by carcinosarcoma of the renal pelvis and urinary bladder, occupying the entire left abdominal flank. We also illustrate the appearance of this rare entity on sonography and computed ...

Three cases of carcinosarcoma of the salivary gland, two in the submandibular gland, and one in the parotid, were investigated with CT and exhibited a variety of findings. The density of the tumors was lower than that of normal submandibular tissue. A calcification was found in one case. One case showed extensive lymphadenopathy. The parotid lesion had low central density with an enhancing margin.

•Secondary uterine sarcomas occur in < 1% of patients treated with CCRT.•Secondary uterine sarcomas can occur > 5 years from CCRT.•The median survival period from the secondary tumor occurrence was only 4 months.•All our patients had heterologous carcinosarcoma of the uterine corpus.

A corneal micropocket assay for angiogenesis in the rat eye is described in detail. With our test system, a partially purified, low molecular-weight endothelial cell growth stimulatory factor isolated from the Walker 256 rat carcinosarcoma is demonstrated to have potent angiogenic activity in vivo. The advantages and applications of our rat corneal assay are discussed.
