Basal cell carcinoma (BCC) is the most common skin cancer in humans, and although metastasis rarely occurs, the tumor cells are nevertheless able to invade and destroy the surrounding tissue. Intralesional injection of IFN-alpha has been found to be highly effective in inducing BCC regression by an unknown mechanism. We show that in untreated patients, BCC cells express CD95 ligand, but not the...

Giant basal cell carcinoma (BCC), defined as a lesion greater than 5 cm at its largest diameter, is a rare variant of BCC. In contrast to small BCC, giant BCC develops on skin that is not exposed to sunlight, including the back, shoulder, groin and thigh. Most of the histopathologic subtypes of giant BCC are micronodular, morpheaform and nodular, but the superficial subtype is rare. Giant super...

Background: Basal cell carcinoma (BCC), the most common form of skin cancer, usually occurs in the sun-exposed areas of the body like head and neck, yet is also seen in unexpected sites. Myriad studies have mentioned a lower limb BCC incidence rate of 1.5-13.5%.Methods: The present retrospective cross-sectional study was conducted on 650 BCC patients, who were referred to the dermatology tumor ...

Background and aim: Basal cell carcinoma (BCC) is the most common skin cancer in white-skin populations. Recent studies suggest that BCC is not a single entity and different histological subtypes show different clinical behavior and might have different etiology. The aim of this study was to assess differences in age, sex, site of distribution and proliferative activity in histological subtypes...

One of the important issues in data envelopment analysis (DEA) is sensitivity analysis. Heretofore the existent studies have considered the data modification of inputs and outputs in one or multiple DMUs. In this paper the number of DMUs is increased and a stability region is obtained in  by applying defining hyperplanes in which if the added DMU (only one DMU) is in this region then all of the...

Background: Basal cell carcinoma (BCC) is the most common skin cancer in whites. Objective: Determination of anatomical localization of BCC in relation to histological subtypes of this tumor. Patients and methods: This survey is a descriptive cross sectional study carried out on 189 cases of BCC patients diagnosed in Hamadan Sina hospital between 1997-1999. Results: This study showed 7 hi...

the aim of this study was to assess the relative efficiency of the iranian forest management plans using the non-parametric method – data envelopment analysis (dea) as a well-known and robust technique for measuring the relative efficiency of organizations. the relative efficiency of forest management plans was calculated using the most frequency dea models such as global technical efficiency (...

Basal cell carcinoma (basalioma, BCC) is undoubtedly the most common malignant skin cancer and the most common human malignancy in general, with the continuous increase in its incidence. BCC is generally a disorder of white individuals, especially those with fair skin. UV radiation is the most important risk factor in the development of BCC. Short-wavelength UVB radiation (290-320 nm, sunburn r...
