A 71-year-old woman presented to the clinic with a one-month history of pruritic, burning, flaky pink to dark red erythematous plaques. The lesions had a very narrow, linear, Blashkoid distribution which extended from the left lateral sole to the popliteal region ( Figure 1). The right leg also had a similar erythematous plaque located at the pretibial region. The patient had no other lesions or previous history of psoriasis. Punch biopsies were performed which revealed orthokeratosis and mounds of parakeratosis, and traumatized Koebnerization. Elongation of rete ridges was not prominent, however, mild psoriasiform hyperplasia and suprapapillary thinning of the epidermis with mildly increased vessels in the dermal papillae and a lymphocytic infiltrate in the upper dermis were observed. (Figure 2A-D). The findings were consistent with features of an early psoriasis lesion.PAS and the direct immunofluorescence (DIF) stains were negative, but Ki-67 showed increased expression ( Figure 2E). Together with the clinical presentation, a diagnosis of linear psoriasis was favored. ABSTRACTA 71-year-old woman presented with a one-month history of pruritus, burning, flaky, and erythematous plaques. The lesions had a very narrow lineal distribution, extending from the lateral left sole to the left popliteal region. Microscopically, the skin biopsy sample revealed orthokeratosis, parakeratosis and traumatized Koebnerization. Elongation of rete ridges was not prominent. The patient had a good clinical response to oral prednisone. Linear psoriasis is a rare variant of psoriasis of unknown etiology. Approximately 23 reports have been published in the English literature. The main differential diagnosis is Inflammatory linear verrucous epidermal nevus (ILVEN). Thorough clinicopathologic findings and response to treatment are all required in the diagnosis and management of this rare form of psoriasis. CASE REPORT

“…Linear psoriasis, a rare form of psoriasis, is characterized by the linear distribution of psoriatic lesions along Blaschko's lines 1 , 2 . Histopathologically, the classic features of psoriasis may be observed 1 , 2 . Herein, we report a case of linear psoriasis on the right side of the trunk.…”

“…Because of clinical and histologic similarity, the main differential diagnosis is inflammatory linear verrucous epidermal nevus (ILVEN) 1 , 2 . Late onset but rapid progression of asymptomatic or slightly pruritic lesions with a possible involvement of the scalp and nails, and a favorable response to antipsoriatic treatment would indicate linear psoriasis 1 , 2 . In contrast, ILVEN lesions that usually appear in the first months of life, are slowly progressive, very pruritic, and highly refractory to antipsoriatic treatment 1 , 2 .…”

In contrast, ILVEN lesions that usually appear in the first months of life, are slowly progressive, very pruritic, and highly refractory to antipsoriatic treatment 1 , 2 . Histologically, ILVEN classically presents with hypergranulosis and orthokeratosis alternating with hypogranulosis and parakeratosis, while Munro's microabscess is considered as characteristic of psoriasis 1 , 2 .…”
