Article Synopsis
- Diagnosing basal cell carcinoma (BCC) in individuals with darker skin tones (dark phototypes IV-VI) is difficult due to varied presentations and fewer identifiable clues; dermoscopy can aid in identifying BCC in these patients.
- This review provides a comparison of BCC's clinical and dermoscopic patterns in people of color to those in lighter-skinned individuals, identifying common mimickers like squamous cell carcinoma and melanoma.
- Key dermoscopic features of BCC in darker skin include blue, black, and gray dots, with arborizing vessels being the primary indicator, while unique conditions in darker skin such as dermatosis papulosa nigra are also considered in differential diagnosis.
