Non-pigmented AK
Strawberry pattern is present
- erythematous pseudonetwork
- prominent yellowish hair follicles surrounded by a white halo (keratin plug)
- grey or brown dots and globules
- Surface scale.

SCC
The hallmark of SCC is keratinisation
- White circles
- White structureless areas
- Looped (irregular) vessels, blood spots common
- Central keratin
- Pink or red background in poorly differentiated or rapidly growing tumours.
+/- Ulceration

Pigemnted BCC
The dermoscopic features of pigmented basal cell carcinoma include:
- Absence of pigment network
- Linear and arborising (branch-like) telangiectasia
- Structureless or leaf-like areas on the periphery of the lesion
- Large blue-grey ovoid nests or blotches
- Multiple blue-grey globules
- Specks of brown and grey pigment
- Spoke wheel areas (radial projections from a well circumscribed dark central hub)
- Focal ulceration

Non-Pigemnted BCC
Much more common than pigmented basal cell carcinoma.
- They contain flecks of grey colour
- typical bluish-pink colour,
- Asymmetrical arborising vessels
- focal ulceration
- Slight scaling and white areas of regression may also be present.
- Chrystalline structures, i.e. white shiny lines, strands and larger irregular-shaped white areas, are common in all histological types of basal cell carcinoma

Milia-like cysts – there are two types:
- Tiny white starry
- Larger yellowish cloudy
Irregular crypts
Fissures/ridges
Blue-grey globules
Light brown fingerprint-like parallel structures
