Linear psoriasis (LP) is a rare and distinct form of psoriasis characterized by its linear distribution along the Blaschko lines. These lines reflect the patterns of embryonic skin progress. This unique presentation often leads to a diagnostic challenge,notably when differentiating it from conditions like inflammatory linear verrucous epidermal nevus (ILVEN),which shares clinical similarities.
Here, we present a case study of a 28-year-old patient diagnosed with LP who experienced persistent and recalcitrant psoriasiform lesions despite conventional treatment options.
Clinical Presentation and Treatment Journey
A 28-year-old patient presented in March 2023 with a history of eczematous and psoriasiform lesions that first appeared in March 2020. These lesions were erythematous, well-defined, and arranged in a linear fashion on the patient’s trunk and extremities. Treatment with topical corticosteroids, vitamin D analogs, and systemic dimethyl fumarate provided inadequate relief, highlighting the need for option therapeutic approaches.
Histopathological examination of a skin biopsy confirmed the diagnosis of LP,revealing psoriasiform epidermal hyperplasia,alternating ortho- and parakeratosis,subepidermal capillary dilatation,and perivascular lymphocytic infiltrates. These findings underscored the importance of histological confirmation in distinguishing LP from clinically similar conditions like ILVEN.
Targeting IL-17: A Promising therapeutic Avenue
“The decision to use ixekizumab, an IL-17A antagonist, was based on its demonstrated efficacy in treating psoriasis and the potential for its effectiveness in this rare variant,” states the patient’s dermatologist.
Within the first 16 weeks of treatment, the patient experienced a remarkable betterment in disease severity. The Psoriasis Area and Severity Index (PASI) score decreased significantly from 12.5 to 1.0, reflecting a ample reduction in lesion size, redness, and scaling. Concomitantly, the Dermatology Life Quality Index (DLQI) improved to 1, indicating a substantial enhancement in the patient’s quality of life.
Clinical Implications and future directions
This case report emphasizes the critical role of histopathological assessment in differentiating LP from other conditions and highlights the potential for IL-17 blockade as a safe and effective treatment option for this rare psoriasis variant. Though, more systematic studies are needed to establish definitive treatment guidelines for LP.
The prosperous treatment of this patient underscores the importance of continued research into rare psoriasis phenotypes and the development of tailored treatment strategies to improve the lives of individuals living with these unique skin conditions.
A Case of Psoriasis: Treatment Journey and Clinical Presentation
A patient presented with a distinct pattern of psoriasis, characterized by sharp-bordered, erythematous and squamous plaques localized to the right side of their body. These plaques, appearing as distinct lesions following Blaschko lines, displayed excoriations, confluent serous crusts, and even isolated hemorrhagic crusts. The patient reported no itching.
The initial lesions, primarily concentrated on the right arm and trunk, later extended to the right hand and knee. Despite efforts with topical therapies involving vitamin A,vitamin D3,and steroids,the condition continued to progress,prompting further inquiry.
A meticulous skin biopsy revealed psoriasiform epidermal hyperplasia, characterized by alternating ortho- and parakeratosis.Neutrophils and lymphocytes were observed exocytosing within the epidermis, and dilated capillaries accompanied by a mixed perivascular infiltrate were noted in the subepidermal layer.The diagnostic journey continued with undifferentiated PUVA therapy and UVB therapy, both yielding no substantial improvement. Systemic treatment with dimethyl fumarate was initiated but ultimately discontinued due to the patient experiencing gastrointestinal side effects.
The patient’s initial presentation, captured in photographs (Figure 1a–f), vividly illustrate the distinctive pattern and severity of the psoriasis. Notably, the sharp border along the anterior median line, restricting the lesions to the right half of the body, adds further clinical significance.
A Psoriasis Area and Severity Index (PASI) score of 12.5, a Body Surface Area (BSA) of 14, and a Dermatology Life Quality Index (DLQI) of 16 underscored the impact of the condition on the patient’s quality of life.

A New Hope for Linear Psoriasis: The journey of One Patient
Linear psoriasis, a rare and challenging variant of the common skin disease, can significantly impact a person’s quality of life. Treatment options are frequently enough limited, and finding effective relief can be a long and arduous journey. This is the story of one patient who,after struggling with debilitating linear psoriasis,found hope through a new treatment approach.
The patient presented with characteristic psoriasiform epidermal hyperplasia, evident in a biopsy that revealed alternating ortho- and parakeratosis with neutrophils. Sadly, initial attempts to manage the condition with systemic dimethyl fumarate alongside various topical treatments proved unsuccessful.
Faced with this primary non-response, the patient and their healthcare provider made a collaborative decision to explore a novel treatment: Ixekizumab, an interleukin-17 (IL-17) inhibitor. Recognizing the limited established guidelines for linear psoriasis, the decision was guided by the proven efficacy, safety, and tolerability of IL-17 inhibitors in treating psoriasis vulgaris.
While awaiting the initiation of systemic therapy, the patient received local treatment with a combined cream of calcipotriol/betamethasone, alternated with a calcineurin inhibitor.
Sixteen weeks after starting ixekizumab, the patient’s skin condition significantly improved. “The pictures reflect the dramatic positive change,” remarked the patient, pointing to clear evidence of postinflammatory hyperpigmentation, as captured in Figure 3.
During their follow-up appointment in April 2024, the patient reported feeling satisfied with the therapy and their Dermatology Life Quality Index (DLQI) score was a remarkable 1, indicating a minimal impact on their quality of life. Only residual erythema without infiltration remained,further demonstrating the effectiveness of the treatment.
“Figure 4 highlights the discreet postinflammatory hyperpigmentation and the reduction in the oil-drop sign on the patient’s nail, a testament to the transformative power of this therapy,” the patient added.
Unveiling the Mysteries of Linear Psoriasis
Linear psoriasis (LP) is a rare and frequently enough misunderstood skin condition that poses a unique challenge for dermatologists. Frequently mistaken for inflammatory linear verrucous epidermal nevus (ILVEN) due to overlapping symptoms and microscopic features,LP’s rarity makes accurate diagnosis challenging.
The clinical presentation of LP is highly variable, with skin lesions appearing in linear patterns across the body. This diversity can lead to misinterpretation and delayed diagnosis. Histological examination is crucial in confirming the diagnosis of LP, distinguishing it from other similar conditions.
Fortunately,advancements in treatment have provided hope for patients with LP.In some cases, IL-17 blockade therapy has shown remarkable efficacy in reducing skin lesions and improving quality of life.
“In mosaic patients with psoriasis, a diligent physical examination and careful histological work-up are essential,” emphasizes a leading dermatologist. This underscores the importance of thorough diagnostic procedures to ensure accurate treatment planning.
The lack of established treatment guidelines for LP further complicates the management process. Given the shared characteristics of LP with certain genodermatoses, collaboration among specialists is vital to develop effective treatment strategies. Immunohistochemical examinations can play a crucial role in personalized treatment selection, shedding light on the underlying disease mechanisms.
The journey to diagnosing and managing LP can be complex,but ongoing research and collaboration hold promise for improving outcomes for individuals affected by this rare skin condition.
Linear psoriasis presents a distinct challenge in the realm of dermatology. Characterized by lesions that appear in straight lines along the skin’s surface, this uncommon form of psoriasis often impacts children and young adults.
While researchers are still unraveling the intricacies of its pathogenesis, studies suggest a potential connection to mosaic somatic mutations in the HRAS gene. ”Mosaic somatic HRAS mutation causes unilateral psoriasis,” explained in a recent study published in the journal *Life*. This genetic anomaly likely contributes to the erratic and often unilateral manifestation of linear psoriasis.
Beyond the genetic component, environmental triggers and immune system dysregulation are believed to play a role in the development and progression of this condition. A 2018 study published in the *American journal of Clinical Dermatology*, which analyzed 30 cases, highlighted the clinical and therapeutic aspects of linear psoriasis, shedding light on its diverse presentations and treatment approaches.
Patients with linear psoriasis can experiance a range of symptoms, including itching, redness, scaling, and thickening of the skin along the lines of a Blaschko. This distinctive pattern, named after the dermatologist who first described it, often follows lines of skin development during embryonic growth.
The article,”Clinical characteristics and therapeutic aspects of Blaschko linear psoriasis,” published in *Dermatologic Therapy* in 2024,emphasizes the importance of recognizing this unique presentation for accurate diagnosis and effective management.
The management of linear psoriasis frequently enough involves a multi-pronged approach, combining topical medications to reduce inflammation and scaling with systemic therapies for more extensive cases.
Oral medications like methotrexate, cyclosporine, and biologics such as ixekizumab have shown promise in controlling the symptoms and progression of the disease.
A 2017 case report in *Case Reports in Dermatology and Medicine*, highlighted the successful treatment of a case of linear psoriasis with ixekizumab, showcasing the potential of this newer class of medications for this challenging condition.Another study, published in *Annales de Dermatologie et de Vénéréologie* in 2022, documented the successful treatment of lower-limb linear psoriasis in a child with ixekizumab, further solidifying its role as a viable therapeutic option for children.
While significant strides have been made in understanding and treating linear psoriasis, ongoing research is crucial to develop more effective and targeted therapies for this unique and often debilitating skin condition.
