In vivo characterization of solitary angiokeratoma by reflectance confocal microscopy and high definition optical coherence tomography

Fig1. Angiokeratoma. A, Clinical appearance showing a blue-black and dark red papule with a crust. B, Dermoscopy showing keratotic scale, hemorrhagic crusts, and rainbow pattern. C, Mosaic of reflectance confocal microscopy showing epidermal cells surrounding the prominent ectatic vascular lacunae (asterisk) forming septa. D, En face mode of high-definition optical coherence tomography showing a branch vessel of the subpapillary plexus (arrow) with a dilatation at the end forming a lacunae (asterisk).
