background: the presence of noncutaneous neoplasms does not seem to increase the risk of cutaneous malignant melanoma; however, it seems to be associated with the development of other hematological, brain, breast, uterine, and prostatic neoplasms. an ecological transversal study was conducted to study the geographic association between cutaneous malignant melanoma and 24 localizations of cancer...

Perivascular epithelioid cell tumors (PEComas) refers to a family of mesenchymal neoplasms composed of angiomyolipomas, clear cell "sugar" tumors of the lung, and lymphangioleiomyomatoses. These tumors have a distinctive and common component of perivascular epithelioid cells that show an association with blood vessel walls and immunohistochemically display myomelanocytic differentiation. The un...

BACKGROUND According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not b...

Background: Leiomyomas are by far the commonest uterine neoplasms in female reproductive age group. Giant leiomyomas quite scarce and when longstanding tend to undergo various degenerations owing decreased blood supply which on imaging may simulate malignancy compromised imaging.Case Presentation: We present a case of 48-year-old post-menopausal multiparous woman complaining intermittent lower ...

A possible association between Friedreich's ataxia (FA) and neoplastic development has been recognized. FA patients have low frataxin levels and insufficient response to oxidative stress. In these patients fibroblasts are characterized by a high rate of mutations. Herein, a case of a 39-year-old woman with FA tetraplegia, who was admitted in our department with intestinal obstruction due to a h...

Primary ovarian leiomyoma is a rare tumor, accounting for only 0.5%-1% of benign ovarian neoplasms. About 80 cases have been reported in the literature worldwide to date. Most cases are asymptomatic and usually found incidentally in routine gynecologic workup, during surgery, or at autopsy. Ovarian leiomyoma is diffi cult to be differentiated from other ovarian benign and malignant neoplasms, p...

Recebido em 22 de julho de 2004 Aceito em 5 de setembro de 2005 *Corresponding author (autor para correspondência) E-mail: [email protected] Reports of tumors of the reproductive tract in female non-human primates are not frequent. In the literature some cases were observed in females, and they included a cervical leiomyoma, an uterine carcinoma (Mcclure and Guilloud, 1971), four ute...

BACKGROUND The vast majority of uterine cervical malignancies are primary carcinomas, and secondary neoplasms that metastasize to the uterine cervix from a distant organ are uncommon. Although relatively rare, metastases to the uterine cervix from a primary colon cancer have been reported. We report a rare case of metastatic carcinoma originating from a cecal adenocarcinoma with an unusual cyto...

The following serum tumor markers are elevated above normal levels in 50 percent or more of patients with various malignant neoplasms: Alpha-fetoprotein in yolk sac tumors, hepatomas, retinoblastomas, embryonal carcinomas, breast carcinomas, and carcinomas of uterine cervix; Carcinoembryonic antigen in colon carcinomas, choriocarcinomas, pancreatic carcinomas, medullary thyroid carcinomas, oste...
