Abstrakt:	Background: Non-melanoma skin cancer (NMSC) is highly prevalent in the United States, with darker-skinned patients (DSP) exhibiting lower incidence but increased morbidity and mortality. The purpose of this study is to elucidate NMSC disparities between DSP (Fitzpatrick skin phototype IV or more) and lighter-skinned patients (LSP, Fitzpatrick skin phototype III or less), focusing on surgical features of non-Mohs micrographic surgery-treated NMSC. Methods: This retrospective cohort study included LSP and DSP diagnosed with either basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) in an academic dermatology setting. Variables collected included age, gender, type of NMSC, location, staging, time-to-diagnosis (TTD), pre-operative lesion size, and post-operative defect size. Categorical variables were reported as counts and percentages, while the association between categorical variables was assessed using a two-tailed Fisher's test. A paired t-test was used to determine the association between continuous variables. P-values <0.05 were considered statistically significant. Results: A total of 27 patients with NMSC were identified, of which 9 (33.3%) were DSP. Patients of darker skin were predominantly female (n=7; 77.8%), while no gender predilection was found in LSP (n=9; 50.0% female; p=0.23). Time-to-diagnosis was significantly longer in DSP than in LSP (61.3 weeks vs 25.1 weeks, respectively; p = 0.02). Despite this, there was no statistical difference in terms of staging, pre-operative lesion size (11.89 mm in DSP vs 10.76 mm in LSP, p=0.75), and post-operative defect size (45.56 ± 29.21 mm in DSP vs 31.22 ± 19.60 mm in LSP; p=0.33). Conclusions: Darker-skinned patients had a longer TTD without staging differences. Our study confirms the need for reducing TTDs for NMSC in DSP. Action initiatives include continued educational efforts to increase awareness of NMSC risk in DSP and more rigorous routine skin cancer screening.
