Type VI (HIV-associated type): Similar to type 1, follicular plugs with spicules are seen. Erythroderma frequently develops. Lesions can be seen together in the setting with acne conglobata, hidradenitis suppurativa, and lichen spinulosus. It is often chronic.

Other conditions that might conceivably be confused with AD include lichen planus, especially if there are larger lesions with lichenification from rubbing, lichen nitidus, and lichen spinulosus. Lichen planus lesions are typically violaceous, polygonal papules that often display the Koebner phenomenon. Lichen nitidus typically presents in children, particularly those of preschool and school age, with numerous, asymptomatic, pinhead-sized papules, often with koebnerization on the abdomen, chest, glans penis, and upper extremities (Tilly et al. 2004) (Fig 3.71). Lichen spinulosus presents as well-delineated patches with multiple keratotic follicular plugs. It may be confused with the patches of eczema in infants with darker skin that display follicular prominence.

Lichen nitidus is an uncommon inflammatory skin condition characterized by typically asymptomatic flesh-colored papules 1 to 2 mm in diameter. Lesions are usually localized to the trunk, upper limbs, and genitalia. Although lesions due to lichen nitidus are usually asymptomatic, some patients report pruritus, requiring treatment.1 Lichen nitidus tends to affect children and adolescents more than adults and does not appear to demonstrate a preference for any race or gender. Though the exact pathophysiology of lichen nitidus is unknown, it has been known to co-occur with lichen planus, erythema nodosum, segmental vitiligo, and lichen spinulosus.2 Several published case reports identify cases of generalized lichen nitidus in children with Down syndrome.3–9 Here, we document another case of generalized lichen nitidus in a child with Down syndrome and synthesize findings from relevant cases. We also share photographed improvement of lesions at 3-month follow-up, something not previously documented in children concurrently affected by lichen nitidus and Down syndrome.
