Background and Aim: Lichen planus (LP) is a cutaneous disease characterized by violaceus flat topped papules in variable size. It may involve body surface areas such as mocus membranes. Some studies have reported an association between oral LP ad diabetes mellitus. The aim of this study was to compare the frequency of diabetes mellitus between patients with and individuals without LP.
Methods: A case-control study was done on 30 patients suffering oral LP as case group and 60 healthy individuals as control group. Diagnosis of oral LP was confirmed by typical clinical and histopathologic findings. Participants in control group were selected from general population after matching for sex and age. Venipuncture was done to take 5 ml blood sample for measuring fasting serum blood glucose levels in both groups. A repeated blood sampling was done for ones with abnormal results in the first sampling. Findings of the study were analyzed using SPSS 16.0 statistical software.
Results: Thirty LP patients [man 13 (43.3%), woman 17 (56.7%)] with mean age (mean±stabdard deviation) of 46±13.7 years and 60 healthy individuals [man 26(43.3%), woman 34 (56.7%)] with mean ages of 46±14 years were recruited to this study. In case group only one person (3.3%) suffered from diabetes mellitus, but none of healthy group had fasting blood sugar above the normal value. In quantative evaluation, mean level of fasting blood sufar was 102.5±33 mg/dL in case group and 111.1±49.3 mg/dLin control group (P=0.09).

Background and Aim: Non-Melanoma Skin Cancer (NMSC), including squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) is the most common cancer in Iran. This study aimed to infer implicit information in the cases of NMSC patients referred to the Cancer Institute of Tehran.

Methods: A number of 865 cases of NMSC related to 2007-2015 years were selected from the archives of Cancer Institute using simple random sampling method. Initially, epidemiological variables, were extracted and after preprocessing of the data, descriptive statistics were used to classify and graphic display of information.

Results: The mean age for patients was identified 65 years and the highest and lowest numbers of cases were in age groups of 69-60 and 19-10 years respectively. The incidence of SCC was higher than BCC in the first four age decades and this trend was reversed in the next decades. About 56% of cases were BCC and 44% were SCC and frequency of NMSC in men was 2/33 times more than women. The head/neck and trunk were the highest and lowest involved positions. The disease had relapsed at least twice in 32% of cases. The disease history showed that most of patients were previously affected by kinds of cancers, cardiovascular or metabolic diseases. The occupation of 114 patients was found to be as high-risk jobs. Most patients were referred to Cancer Institute from northern and western parts of the country.

Conclusion: Along with other studies, we found more cases of BCC than SCC, involvement of patients over 60 years at the head-neck and a previous history of cancer. But against other studies, SCC cases was found more in the first four decades of life than BCC cases, feet affected twice than hands and the locality of most cases was found in high latitudes. Patient records are potential resources that can help management of the diseases.
