A study on incidence of Epidermal Tumors

Abstract

Introduction: A skin tumor encompasses a vast area of pathology, because skin is a heterogeneous organ with many varied elements having ectodermal and mesodermal origins. The surface epidermis tumors are the most common group of neoplasms. The most of the tumors appears as sebaceous cysts but FNAC and Histopathology examination is the confirmatory. The present study confirmed many tumors. Methods: The total 1332 tumors which are registered for Histo pathology examination are taken as a Study group. The study is retrospective and prospective with regard to skin tumors. The skin tumors collected over a period of 4 years from the Department of Pathology, S.V.Medical College, Tirupati and diagnosed. The paraffin embedded present and previous blocks collected and cut to 5 micron sections and stained routinely with haematoxylin and eosin and examined microscopically for establishing the precise nature of lesions. Results : - About 1332 were the number of total tumors recorded in the Department of Pathology, out of these number of skin tumors were 114, giving incidence of 8.6%. Among the total skin tumors of 114, the epidermal tumors are 80 and incidence rate is 68%. The surface epidermis tumors were the predominant group with incidence of 69% followed by adnexal tumors with 26%incident and the least incidence shown by melonogenic tumors of 14% incidence. Among the skin tumors recorded with the study are majority of the lesions occurred between the 5 th ,6 th , and 4 th decades giving incidence of 24.94%,19.78% and 18.92% with peak age incidence between 41-50 years. Benign skin tumors displayed peak incidence in the forth decade. Conclusion: - out of a total of 1332 the skin tumors are 114(8.6%) were skin tumors accounting for 114 cases (99.56%) and secondary deposits accounted for only 1 case (0.86%) and unclassified 1 case 0.86%.
