Table 1.

Summarizes the most frequent dermatoscopic characteristics of skin cancer subtypes (BCC, SCC and melanoma) in Skin of Colour patients.

Skin cancer in skin of colour	Dermatoscopy characteristics
BCC in Hispanics	the chance of pigmentation for BCC is twice as common as in white patients. the main dermatoscopic finding for nodular BCC was blue-gray ovoid nests. The main dermatoscopic feature for pBCCs were the shortened vessels, the gray-blue ovoid nests and the maple-leaf like regions. In superficial BCCs the spoke-wheel areas and shortened vessels were mostly seen. A blue-white veil subtype of BCCs can be observed.
BCC in Asians	III – IV phototype populations The majority BCCs are pigmented or at least with pigmented structures in dermatoscopy Similar dermatoscopic features and approach as that of Caucasians Branching vessels as the dominant vascular pattern. The presence of other vascular formations has a low diagnostic value in this population IV–VI phototype populations Ulceration, blue-white veil, and branching vessels are significantly associated with nodular BCC Maple leaf-like areas, the red-white structureless areas, multiple small erosions, and radial wheel areas were noted in the surface BCCs
BCC in Blacks/Africans	Pigmented subtypes with characteristic structures that are also observed in white populations (maple-like leaves, radial wheel structures, etc.) are reported. Reticular pigmentation can be observed in the surrounding uninvolved skin, more intense around the lesion and central hypopigmentation.
SCC in Hispanics	Very limited literature on SCC in this population and on its dermatoscopic features The dermoscopic features observed are similar to those described in white subjects, but there is a higher incidence of pigmented variants
SCC in Asians	III – IV phototype populations Glomerular vessels plus a squamous surface were the most common dermoscopic findings of BD High probability of detecting pigmentation dermatoscopically Common dermatoscopic findings for pigmented BD included dotted vessels, hairpin vessels, a pink-white network, and a pink-white structureless area. IV–VI phototype populations A combination of pigmented structures associated with Bowen’s disease is often seen
SCC in Blacks/Africans	The dermoscopic features observed are similar to those described in white individuals, but there is a higher incidence of melanocytic variants. Dermatoscopically, loss of the normal pigmented network surrounding the lesion of squamous cell carcinoma can be observed.
Melanoma in Hispanics	Dermatoscopic features of melanomas in Hispanics are similar to those in Caucasians; Dermatoscopic features such as whitish blue veil, bright white structures and milky red areas were reported
Melanoma in Asians	Usually, melanomas of specific location They may appear dermatoscopically with an asymmetric colorful pattern, blotches, blue-white veils. atypical pigment networks, irregular peripheral striae, atypical vascular patterns, ulcer, atypical dots/balls bright white lines and hypopigmented structures The most common vascular pattern seen in melanoma was linear and irregular vessels.
Melanoma in Blacks/Africans	High incidence of palmoplantar melanomas that show a parallel ridge pattern There may be loss of pigmentation surrounding the lesion itself, creating a hypopigmented “halo”
