Benign epidermal tumors and proliferations. Lichen striatus LS is a benign, uncommon, self-limited, linear inflammatory skin disorder that primarily affects children up to 15 years of age, most commonly around 2 to 3 years of age, and is seen more frequently in girls.

The lesions may be erythematous, flesh colored, or hypopigmented. Most cases spontaneously resolve within 1 year. Digital involvement may result in onycholysis, longitudinal ridging, splitting, and nail loss. Treatment is not necessary but options include topical steroids, topical retinoids, and topical calcineurin inhibitors. Epidermal changes include intercellular and intracellular edema, focal spongiosis, lymphocytic exocytosis, parakeratosis, patchy hyperkeratosis, and keratinocyte necrosis Figure 2A.

Figure 1. Figure 2. Another condition that distributes linearly along the lines of Blaschko is linear epidermolytic hyperkeratosis EHK. Similar to LS, histology shows hyperkeratosis, focal parakeratosis, and acanthosis of the epidermis. Figure 3. Linear lichen planus LLP , similar to LS, histologically shows a lichenoid lymphocytic bandlike infiltrate obscuring the dermoepidermal junction, vacuolization of the basal cell layer, and pigment incontinence.

Linear lichen planus characteristically consists of wedge-shaped hypergranulosis and irregular acanthosis with saw-toothed rete ridges Figure 4. Linear porokeratosis can be mistaken for the linear lesion of LS. Both entities may reveal perivascular lymphocytes in the dermis, and porokeratosis can be lichenoid in the central portion of the lesion. Figure 5. Similar to LS, linear psoriasis follows lines of Blaschko clinically. However, it is distinguished by its characteristic psoriatic epidermal changes as well as its lack of lichenoid or perieccrine inflammation.
