Progressive vitiligo visualised by UV dermoscopy (x20) which better delineates the perifollicular pigmentation and fuzzy borders in the depigmented macule compared to polarized microscopy (x20) (Source: Yuan et al.)[5]
Figure 2
Figure 2
Infrared dermoscopy showing different patterns of malignant and borderline malignant lesions highlighting areas with different metabolic activity (Source: Ferrari et al.)[12]
Figure 3
Figure 3
Optical coherence tomography (6 mm × 1.5 mm) (a) and corresponding histology (H and E, 50x) (b) of a basal cell carcinoma on the lower eyelid. The distribution of signal in the malignancy is more homogenous compared to adjacent healthy skin (Source: Welzel et al.)[21]
Figure 4
Figure 4
Melasma on the left cheek of a 61-year-old female patient. (a) Dermoscopy shows a thin pigment network with arcuate and annular structures sparing follicular openings. (b) Bright-edged papillae at the dermo-epidermal junction (DEJ) and hyper-reflective cobblestone pattern observed at the supra basal layer. The angulated, bright-edged papillae (yellow arrowhead) at the DEJ correspond to the pigment network on dermoscopy. (c) Increased keratinocyte pigmentation with few dendritic cells (red arrowhead). (d) Within dermal papillae, large oval bright structures (red circle) are seen, representing melanophages (Source: Farabi et al.)[37]

Photoacoustic images at 532 nm illumination wavelength of (a) Abdominal (i) melanoma lesion, and (ii) healthy; (b) Flank (i) melanoma lesion and (ii) healthy; (c) Bar chart of photoacoustic signal intensity. Higher signal intensity from melanoma lesion due to the presence of an increased melanin in the epidermis and, therefore, higher absorption compared to normal skin (Source: Kratkiewicz et al.)[51]
