(A) Dermoscopic image of a fully developed lesion showing whitish scales (arrows), brown-red structureless areas with poorly defined borders (red stars), multiple irregularly distributed brownish blue-gray dots and globules (yellow stars), and blue-white veil like structures (white ovals) over a background of erythema (DermLite II, hybrid M, ×10, polarized).(B) Resolving lesions demonstrated brownish background reticular pigmentation surmounted by volcano-like islands composed of multiple irregular brown-gray dots and prominent linear blood vessels (white arrows, DermLite II, hybrid M, ×10, polarized). (C) Histopathology revealed mild hyperkeratosis, acanthosis, and superficial dermis showing perivascular inflammation on low power view. (D) Histopathology revealed basal cell vacuolization, pigment incontinence, apoptotic keratinocytes (arrow in inset), neutrophilic exocytosis, and interface dermatitis evident on high power magnification.
