Epidemiological and localization characteristics of non-melanoma skin cancers: Retrospective analysis of 400 cases

Abstract

Aim: In this study, it was aimed to investigate the epidemiological and localization characteristics of the patients diagnosed with nonmelanocytic skin cancer (NMSC). Materials and Methods: Histopathologic results of patients diagnosed with NMSC in the Pathology Department of Necmettin Erbakan University, Meram School of Medicine, between 2007 and 2017 were retrospectively reviewed. The age, sex, tumor type, and localization of the patients were investigated. Results: A totals of 400 patients diagnosed with NMSC were identified. 220 of the patients were male (55%) and 180 were female (45%). The male to female ratio was 220/180 (1.22). The age range was 10–105-year-old and the mean age was 67.8. Basal cell carcinoma (BCC) was found in 263 patients (65%), squamous cell carcinoma (SCC) in 114 patients (28%) and baso SCC (BSCC) in 12 patients (3%). BCC and SCC were observed together in 9 patients. BCC was most commonly detected in the nasal region with (31%) 82 patients (50%). SHC was most commonly detected in the lower lip region with 26 patients (22%). The localization of the BSCC was most common in the nasal region with 6 patients (%50). The rate of BCC/SCC in the nasal region was 82/11. The BCC/SCC ratio in the extremity region was 4/14. Conclusion: In our region, the most frequent histopathologic diagnosis was found BCC in patients prediagnosed with NMSC, and most cases were seen in male patients. In cases of BCC a BSCC, the most common tumor localization was nose area while it was lower lip area in SCC cases. In addition, BCC and BSCC were not detected in the lower lip.
