Since the incidence of injury is taken into consideration in the pathologic diagnosis, the study of clinical and microscopic views of BCC is of particular importance. The present study aimed at determining the frequency of clinical and microscopic views of BCC in a 10-year period in Ilam province.</span><br> <strong><span dir="LTR">Materials and Methods</span></strong><span dir="LTR">: This study is descriptive. The study population consisted of all the subjects with BCC in the head and neck area referring to the pathology department of Imam Khomeini hospital in Ilam province in a 10-year period. The data were entered into SPSS 19 software and were analyzed using descriptive statistical methods and Chi-Square test.</span><br> <strong><span dir="LTR">Results: </span></strong><span dir="LTR">In the present study, 205 patients were diagnosed with BCC. The maximum and minimum frequency rates of the lesion were detected in the frontal area (9.23%) and neck (8.7%), respectively. The maximum frequency was related to the nodular type (57.1%), while the pigmented variant showed the lowest rate (8.3%). Among the evaluated microscopic variants, maximum views were related to the solid-cystic type (57.1%), while minimum views were related to the pigmented variant (37.3%). There was no significant correlation between the location of the lesion in males and females (p=0.14) or between the location of the lesion and age (p=0.16).</span><br> <strong><span dir="LTR">Conclusion: </span></strong><span dir="LTR">The results of this study showed that the nodular type was the </span><span dir="LTR">most common clinical</span><span dir="LTR"> variant of BCC</span><span dir="LTR">, while the least common type was the pigmented variant. The most common histological type was the solid-cystic type, while the pigmented variant was the least common type. </span><br> &nbsp;</p> کانسر پوست – بازال سل کارسینوما – پیگمانته skin neoplasms, Basal Cell Carcinoma, cancer 39 44 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-362-2&slc_lang=en&sid=1 KH Abdal dr.faribaabdal@yahoo.com 10031947532846009066 10031947532846009066 No Assistant professor,Oral Pathology Dept, Faculty of Dentistry, ilam university of medical sciences J Salehinejad j-salehinejad@yahoo.com 10031947532846009067 10031947532846009067 No Professor, Department of Oral Pathology, Faculty of Dentistry, mashhad University of Medical Sciences, Mashhad, Iran S Mostafazadeh fariba4479@yahoo.com 10031947532846009068 10031947532846009068 Yes Assistant professor,Oral Pathology Dept, Faculty of Dentistry,urmia University of Medical Sciences, Urmia, Iran
