A case of unilateral linear lichen planus: related to orthopedic prosthesis or not?

A Review of Linear Lichen Planus Case Reports

ABSTRACT

Lichen linear planus is a rare variant of lichen planus that appears as pruritic, polygonal, purple papules in a blaschkoid distribution. This review critically assesses all reported cases of linear lichen planus (LLP) for proposed etiology, clinical and histologic traits, treatment options, and recurrence. A PubMed search from inception through March 2023, followed by article screening and full-text review, identified 51 unique cases of LLP. Data from each case including the sex of the patient, anatomic distribution of lesions, biopsy results, proposed etiology, treatment, and recurrence were recorded. LLP did not show a significant gender or age predilection, most frequently presented unilaterally with pruritus, and involved numerous anatomic regions. Various triggers including metal implants, vaccinations, infections, malignancy, and pregnancy were identified. The most common histopathologic descriptions included band-like lymphocytic or lichenoid infiltrate, basal liquefactive, vacuolar degeneration, hypergranulosis, hyperkeratosis, civatte or colloid bodies, melanin incontinence, and orthokeratosis. Treatment options, duration of treatment, and recurrence rate of LLP lesions were variable. Although LLP is rare, dermatologists should be aware of this presentation and appropriate diagnostic and treatment options because swift diagnosis can reduce patient morbidity.

Orthopedic Dermatopathies: Skin Manifestations in Orthopedic Conditions

Orthopedic diseases often present with dermatological symptoms that require prompt identification for appropriate treatment. Understanding these dermatologic presentations is crucial for accurate diagnosis and effective management. This article critically reviewed the dermatological manifestations observed in general and regional pathologies, followed by treatment-related manifestations. An extensive literature search was performed and limited to manifestations in orthopedic disease, excluding those pertaining to infection or syndromes. Case reports and case series documenting unusual and rare dermatologic presentations of orthopedic conditions were examined, providing novel perspectives on both prevalent and uncommon illnesses. The identified pathologies are discussed in detail, including their clinical features and diagnosis, while treatment approach varies depending on the severity of the condition, ranging from self-care to surgical intervention. The findings emphasize the need for interdisciplinary collaboration and highlight the importance of careful diagnosis and appropriate management to eliminate unnecessary approaches and ensure optimal outcomes for patients with orthopedic diseases and dermatologic symptoms.

Treatment modalities of palmoplantar lichen planus: a brief review

Palmoplantar lichen planus is a localized and uncommon variant of lichen planus which is mostly resistant to treatment. Our purpose was to discuss all treatment modalities proposed and tested for palmoplantar lichen planus in the literature. A systematic review of the literature was conducted to evaluate evidence regarding all treatment modalities proposed and tested for palmoplantar lichen planus in the literature. Two major databases (PubMed, Google scholar) were searched. The review included all case reports, letters and original articles reporting any treatment for palmoplantar lichen planus but not treatment used in the other type of lichen planus, generalized lichen planus or other type of palmoplantar dermatoses. We have gone over more than 50 articles. There are many drugs that have been used in the treatment of lichen planus and generalized lichen planus but the palmoplantar type is a rare variety of lichen planus. That is why we could not find any clinical trial on the subject and just case reports have been described in this manuscript. In spite of plentiful investigations carried out on lichen planus, there is no treatment modality that has proved to be utterly satisfactory in treatment of palmoplantar lichen planus.
