Primary ovarian angiosarcoma is a very rare gynaecological sarcoma, with poor prognosis. These tumors are though to arise from carcinosarcomas, teratomas, or the ovarian vasculature and occur at any age. There are only a few cases reported in the international literature, most commonly associated to surface epithelial-stromal or germ cell tumours. Herein,… (More)
Screening tools have greatly improved prostate cancer (PCa) detection, but the disease course is heterogeneous, and standard clinicopathological parameters do not fully discriminate aggressive from indolent tumors. To evaluate the prognostic value of the TMPRSS2-ERG fusion gene combined with chromosome arm 8q relative gain in diagnostic biopsies of PCa, we… (More)
Risk factors for acquisition of imipenem-resistant Pseudomonas aeruginosa by hospitalized patients were assessed at a tertiary care hospital. Two case-control studies with different control groups were used. In Study 1, patients with imipenem-resistant P. aeruginosa (IRPA) (case group) were compared with patients selected at random from the same unit. In… (More)
Primary liver sarcomas represent a rare group of neoplasias, with angiosarcoma being the most common histological type. Primitive neuroectodermal tumor (PNET) represents a high malignant neoplasia that usually affects the central nervous system and soft tissues. An 18-year-old male patient was admitted with clinical complains of pain in the right upper… (More)
Carcinoid is a rare gastrointestinal tumor, with an incidence varying from 1 to 2.5 per 100,000 in the general population. In this article, we report an elevated incidence of carcinoid tumor in an obese population, showing the importance of performing an endoscopic procedure before bariatric surgery.
CONTEXT Adrenocortical virilizing tumors are rare in the pediatric age group. Laparoscopic surgery is the gold standard method for treatment of adrenal functional tumors under 6 cm in size, in adults. There has been very little use of laparoscopy in children and there is no report of its application in the treatment of adrenal carcinoma in childhood. … (More)
[reaction: see text]. The reaction of unsubstituted indole with different acylating agents such as acid chlorides, anhydrides, nitriles, and amino acid derivatives in the presence of Lewis acid is reported.
BACKGROUND Historically, tertiary syphilis infection has been the most common cause of thoracic aortic aneurysm, resulting in 5% to 10% of cardiovascular deaths until the era of antibiotics. METHODS A 49-year-old Caucasian man presented to our institution with progressive dysphagia, weight loss, incomplete bladder emptying, alcohol and tobacco… (More)
Primary tumors of the esophagus can be classified on the basis of cell origin into epithelial and nonepithelial tumors. Each category may be further subdivided into benign and malignant types. The nonepithelial tumors arise from the mesenchymal or supporting stromal tissue, most of them are benign. Nearly all esophageal cancers are carcinomas. Sarcomas… (More)
