The primary squamous cell carcinoma of prostate is a rare tumor that its histogenesis has not been clearly identified. This tumor comprises 0.5 to 1 % of malignant tumors of prostate. In most cases, there exists a severe and atypical metaplasia. The case was a 66 years man that admitted for increased frequency of urination and a burning sensation.

background: carcinomas of esophagus, mostly squamous cell carcinomas, occur throughout the world. there are a number of suspected genetic or environmental etiologies. human papilloma virus (hpv) is said to be a major etiology in areas with high incidence of esophageal carcinoma, while it is hardly detectable in low incidence regions. this study was designed to evaluate the prevalence of hpv in ...

the role of oxygen free radicals in the initiation, promotion and progression of carcinogenesis and the protective role of anti-oxidant defenses has been the subject of much speculation in the recent past with conflicting reports in the literature. in recent years, increasing experimental and clinical data have provided compelling evidence for the involvement of oxidative stress in a large numb...

basaloid squamous cell carcinoma of the esophagus are rare [1–4], while esophageal combined carcinoma is very rare [5]. Most cases of combined carcinoma of the esophagus consist of squamous cell carcinoma, adenocarcinoma, and small cell carcinoma [5].

Non-melanoma skin tumors are a fairly common. Squamous cell carcinoma of the is characterized by particularly high malignancy, which due to ability metastasize. However, it has also been shown that patients with basal have an increased risk developing squamous carcinoma. The molecular phenotype these tumors, as well markers progression, not studied.

the purpose of the present study was to estimate the frequency of hpv dna in four groups of oral lesions, including oral squamous cell carcinoma. sixty paraffin-embedded oral tissue samples were examined for the presence of hpv dnas using the pcr technique. these specimens were obtained from patients with oral squamous cell carcinoma (oscc), leukoplakia, oral lichen planus (olp), and pyogenic g...

background: although the imbalance of cytokines in head and neck squamous cell carcinoma (hnscc) is well known, there is scarce data regarding its occurrence during dysplasia, before the malignant transformation. objective: to determine whether laryngeal dysplasia patients show a different cytokine profile than patients with cancer and healthy controls. methods: seventeen newly diagnosed, untre...
