Background/Objectives: Skin cancer is increasingly prevalent. Non-melanoma skin cancers pose a challenge, as most lesions are diagnosed at later stages and often lead to complications. Although dermatoscopy has emerged valuable tool that enhances the confidence of dermatologists, specific patterns for accurately identifying various subtypes non-melanoma have yet be detailed. This study aimed investigate dermatoscopic clues facilitate accurate diagnosis among dark-skinned Mexican individuals. There insufficient acknowledgment high rates non-Whites. Methods: The included fifty-three patients with cancer, aged 39 89, who visited an academic dermatology department examinations. Two certified dermatologists evaluated least three images each lesion. A biopsy was taken confirm preliminary diagnosis. Statistical analysis performed using GraphPad Prism v8.0, considering probability (p) value less than 0.05 significant. Results: Most were classified phototype III. Patients IV younger time Basal cell carcinomas common subtype. Nodular ulcerated tumors prevalent morphology. examination revealed 60% pigmented, predominance polymorphic vascular patterns. Squamous exhibited monomorphic structures. Both groups' blood vessel arrangements primarily radial. Conclusions: did not demonstrate effectiveness criteria in distinguishing basal from squamous carcinomas. However, certain factors, such pigmentation linear vessels, seem occur more frequently nodular
