Non-melanoma skin cancers (NMSC) are malignancies that are common especially in the elderly population and are closely associated with sun exposure, and they represent an important public health problem with an increasing incidence in our country. This retrospective study aimed to evaluate the demographic and clinical characteristics of NMSC cases diagnosed in the region and to compare the findings with the literature. The clinical data of 70 patients diagnosed with NMSC in the Dermatology outpatient clinic between March 2024 and November 2025 were reviewed. Age, sex, tumor type, lesion localization and number, clinical subtype, lesion development duration, history of previous skin cancer, and immunosuppression status were evaluated. Of the 70 patients, 49 (70%) were diagnosed with basal cell carcinoma, 19 (27.1%) with squamous cell carcinoma, and 2 (2.9%) with basosquamous carcinoma. The mean age of the patients was 72.8 years, and cases were most frequently observed in the 70–79 age group with male predominance. Most of the lesions were located in the head and neck region, and the most frequent site was the face, particularly the nose. The most common clinical subtype was the nodulo-ulcerative form in basal cell carcinoma, whereas hyperkeratotic and eroded/ulcerative nodular subtypes were predominant in squamous cell carcinoma. The mean lesion development duration was 9 months and the median was 6 months. Immunosuppression was detected in only 2 patients. This study is the first to present epidemiological data on NMSC in the Amasya region, and the findings are consistent with the literature.
