Correlation of dermoscopic and histopathological changes in lupus vulgaris

Dermoscopic patterns	Histopathological correlation
Yellowish-white globules	Dermal granulomas
Pinkish-red background	Widespread vasodilatation
Dotted vessels	Tips of normal vertical papillary loops
Red globules	Tips of ectatic/elongated papillary loops
Linear vessels	Ectatic/elongated subpapillary capillary plexus
Ulceration	Erosions in the epidermis and dermis
Whitish structureless areas*	Acanthosis and dermal fibrosis
Superficial white or yellow scales	Hyperkeratosis and/or parakeratosis
White shiny streaks	Orientation of collagen bundles in different angles in the dermis
Follicular plugs	Keratotic material in follicular infundibulum
Patulous follicles	Dilatation of infundibulum
Bluish hue	Orthokeratosis

*White structureless area correlate with keratin (acanthosis) and collagen (fibrosis)
