PURPOSE To assess the accuracy of MR imaging in predicting dural, venous sinus, and perineural invasion by skull base tumors. METHODS The preoperative MR images of 22 patients who had resection of skull base neoplasms were evaluated for the following characteristics: dural enhancement, pial enhancement, local perineural invasion by adjacent tumor, and venous sinus invasion by tumor. The great...

Background: Aggressive angiomyxoma is a rare mesenchymal tumor with extensive local invasion. It often presents with a lump in the perineal area and pelvic. Since it often does not involve adjacent organs such as the urethra and anus, does not cause obstructive symptoms. Its incidence is 6 times higher in women than men. This tumor grows slowly and has a slight tendency to metastasize. However,...

Extramammary Paget's disease (EMPD) is a rare malignancy, and little was known about its prognostic factors and optimal treatment. In the current study, we aimed to discuss clinical and pathological features of scrotal EMPD and determine the prognostic factors for cancer-specific survival and local recurrence. A total of 206 patients with scrotal EMPD lesions surgically treated at our institute...

Abstract Nowadays, as accepted as the era of information or digital, time has changed and has invited all people to a new world in which everybody must define himself. Avoiding from getting benefit from this human progress is useless; Rather, we must know this great technology best and adapt ourselves with its consequences. In fact, in many countries and among many nations there had been peopl...

Many pathogenic bacteria cause local infections but occasionally invade into the blood stream, often with fatal outcome. Very little is known about the mechanism underlying the switch from local to invasive infection. In the case of Neisseria gonorrhoeae, phase variable type 4 pili (T4P) stabilize local infection by mediating microcolony formation and inducing anti-invasive signals. Outer membr...

OBJECTIVE To analyze the prognostic factors related to the recurrence rate of vulvar cancer. METHODS Retrospective study of 87 patients diagnosed of vulvar squamous cell carcinoma diagnosed at a tertiary hospital in Madrid between January 2000 and December 2010. RESULTS The pathological mean tumor size was 35.1±22.8 mm, with stromal invasion of 7.7±6.6 mm. The mean free margin after surgery...
