Dermatologists routinely use dermoscopy in the evaluation of pigmented and non-pigmented skin lesions but may be unfamiliar with usual global and local dermoscopic features of lesions on the vulva. Digital imaging of this site can be diffi cult; images are clearer if lubricant or antiseptic gel is applied to the lesion. The instrument ’ s glass plate can be protected with stretched cling fi lm. Angiokeratomas, viral warts and molluscum contagiosum are easy to recognise with a good light, magnifi cation and fl uid immersion or polarisation. Melanocytic lesions on hair-bearing areas of the genitalia and mucosal surfaces typically appear ‘atypical’ with complex patterns. Asymmetry of structure and colour and specifi cally, blue colour, are characteristic of melanoma which may also have atypical vascular pattern. Vulval intraepithelial neoplasia may resemble seborrhoeic keratosis. Lentigines and melanosis have structureless, ring-like and parallel dermoscopic patterns.
