Our purpose was demographic clinical and pathological aspect of BCE in patients seen in Razi Hospital, during a six-month period (75.8.12 to 76.2.12). Results: From the total 20000 patients, 103 cases of BCE were detected. (0.5%). The male female ratio was 1.71 BCE was more frequent in sixth decade. 40.8% of patients were fair skin (Type II), 54.4% tawny (Type III) and 4.9% brown (Type IV, V). 15.5% of patients had a past history of freckles and history of radiotherapy in childhood was present in 41.7% 89.3% had no history of acne and seborrhea. The scalp was the most common site of BCE. The most common clinical type was nodular BCE and solid BCE was the dominant histological feature. Conclusion: BCE was more common in male and fair skin patients with dry skin. In those having history of radiotherapy of the scalp, lesions were seen mostly on the scalp, forehead and neck: pigmented BCE was predominant in this group.

Background: Long term use of immunosuppressive therapy in transplant recipients in order to prevent acute and chronic rejection increases the long term risk of cancer. This study evaluates the incidence of different organs’ cancer after renal transplantation and immunosuppressive therapy.
Methods: This is a retrospective analysis of malignant tumors in renal graft recipients with more than one year graft survival. Patients were assessed according to their age, sex, diagnosis of cancer, immunosuppressive drugs, donors and period of dialysis before transplantation.
Results: Evaluating all existing files in selected private clinics in Isfahan 350 patients were reviewed and 289 of them had entrance criteria. A total of 186 men and 103 women (mean age: 42.17±13.09 years) were included. They were followed up over a mean period of 52.46±33.24 months. A total of six cases (2.1%) of cancer were diagnosed in six recipients: All patients with cancer were male with a mean age of 51.17±14.7 years (range: 26-68 years). Tumor presented at a mean time of 51 months (rang: 15-82 months) after transplantation. There were two patients with BCC, two patients with SCC and two patients with lymphoma. Two patients died of progressive malignant disease. Age, period of dialysis before transplantation, and using immunosuppressive and anti-rejection drugs had no significant impact on development of post transplant malignancy.
Conclusion: The frequency of tumors in these patients is lower than what reported by other centers, probably due to short period of follow up and low incidence of cancer in our general population. The risk of malignancy was 28 fold higher among transplant recipients than in general population. High risk of cancer in this group, confirms the necessity of routine examination for organ transplant recipients both before and after transplantation.
