as a tumor composed of admixed benign epithelial and malignant nonepithelial components, and this tumor usually develops as a solitary lesion in the uterine corpus (1). These neoplasms can develop in the endometrial tissue as well as in the ectopic foci of endometriosis. Rare extrauterine müllerian adenosarcomas have been reported to arise in the ovary, cervix, vagina, pelvis, bladder and colon...

S ince 1970, cancer of the uterine cervix has accounted for 10% of all new cases of malignant neoplasms occurring among women in Cuba. Although the age-adjusted incidence rates in women 30-74 years of age have decreased from 41.3 per 100 000 women in 1970 to 37.8 per 100 000 in 1990, mortality from this cancer has not changed significantly over the past 10 years (I). This situation exists in sp...

With the exception of leiomyomas, soft tissue tumors of the uterine corpus are not common. This is particularly true for vascular neoplasms, with the epithelioid hemangioendothelioma being a curiosity; not more than twenty-two cases of malignant hemangioendotheliomas have been reported in the literature so far, all of which were high-grade hemangioendotheliomas (hemangiosarcomas). We present he...

From march 1996 to January 1997 we enrolled 14 consecutive patients, median age 53 years (range 3274), Performance status 1 or 2, affected by histologically proven uterine neoplasms. PET imaging was performed using a whole body PET-camera (Siemens EXACT 47 scanner). All patients were submitted to PET with FOG (370 MBq i. v., pelvic and whole body images) before radiotherapy. Fluorine 18 was pro...

The presentation of antigenic peptides by MHC class I molecules is important for tumor rejection by CTLs. Such antigenic peptides are generated as a result of the degradation of intracellular proteins by the proteasome pathway, a process that is influenced by the IFN-gamma-inducible low molecular mass polypeptide-2 (LMP2) subunit of the proteasome complex. LMP2 knockout mice thus exhibit a defe...

Uterine cervix carcinoids are distinct neuroendocrine cervical tumors, representing a comparatively small percentage of them. These well-differentiated neoplasms are far less prevalent than small- and large-cell carcinomas, characterized by a more favorable biological course. We report a case of a 43-year-old woman with a nonmetastatic cervical carcinoid, managed with radical hysterectomy. She ...

The clinical and pathological features of 20 patients with coexistent squamous cell carcinoma and adenocarcinoma of the uterine cervix have been analyzed. Various combinations of in situ and invasive carcinomas were found. Located adjacent to each other and at times intermingling, these lesions probably originated from the subcolumnar reserve cells of the transformation zone. They are early les...

Granulocytic sarcoma (GS) is a solid tumor that is the extramedullary presentation of acute myelogenous leukemia, other myeloproliferative disorders, or myelodysplastic syndromes. Less commonly, it also may arise as an isolated mass. In this report, we describe a 23-year-old female patient, with a GS in the uterus and we stress the value of diffusion weighted imaging for the evaluation of uteri...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

Background: The carcinogenic effect of asbestos is accepted for lung cancer and mesothelioma, while conflicting opinions exist for other cancer sites. The aim of the present investigation is to study cause-specific mortality of women compensated for asbestosis who had certainly been exposed to high levels of asbestos fibers. Methods: The cause-specific mortality of all Italian women compensated...
