Oral lichenoid drug eruption: a report of a pediatric case and review of the literature

Lichenoid Lesions of the Oral Mucosa

Lichenoid lesions involving the oral cavity present with an array of complex clinical manifestations and etiologies. The etiology ranges from local factors, systemic entities, and even autoimmune conditions. Several different types of lichenoid lesions may affect the oral cavity, and it is imperative that these are correctly diagnosed to ensure effective patient care. Lichenoid lesions such as chronic ulcerative stomatitis prove to be challenging as these are recalcitrant, present with overlapping features, require unique treatment and patients suffer a long time if not promptly diagnosed.

Oral fixed drug eruption: Analyses of reported cases in the literature

BACKGROUND

This analytic study aimed to summarize the data regarding OFDEs manifestations and characteristics available up to date.

MATERIALS AND METHODS

We searched online databases for relevant articles and summarized their data regarding age, gender, Main drug classification and name, additional drugs, dosages, primary disorders, OFDE presentation and location, extra-oral presentation and location, follow-up, and treatment.

RESULTS

The mean age of OFDE-affected patients was 38.9. Most of the reported cases were between 30 and 60 years of age. The female/male ratio was 1.12/1. Three drug classifications, which were mainly associated with OFDEs, were analgesics (27.8%), antibiotics (22.2%), and antifungals (11.1%). The most common additional drugs were oral contraceptives and corticosteroids. The three most prevalent disorders or conditions were infectious disease (23.7%), pain (13.2%) and auto-immune disease (10.5%). Erythematous lesions without blister (38.9%), lichenoid drug eruptions (16.7%), blisters/vesicles (13.9%) and ulcers (13.9%) were the most common manifestations of OFDEs. The rarest manifestation of OFDE was pigmentation. Lips, tongue, buccal mucosa, palate and gingiva were the sites in which OFDEs occurred in the included studies. Similar to OFDEs, erythematous lesions without blisters and lichenoid drug eruptions were the most prevalent extra-oral manifestations. The most common time for OFDE manifestations was one to three days after taking the drug.

CONCLUSIONS

Due to the similarities between the reported cases of OFDEs, clinicians should familiarize themselves with OFDE cases in order to screen suspected patients effectively.

Demystifying Esophageal Lichen Planus: A Comprehensive Review of a Rare Disease You Will See in Practice

Lichen planus (LP) is a chronic inflammatory disorder that often affects the skin, hair, nails, and mucus membranes. Although esophageal involvement has traditionally been felt to be rare, recent reports suggest that it is often unrecognized or misdiagnosed. The diagnoses of esophageal lichen planus can be challenging and is suspected based on patients' endoscopic and histologic findings and in the context of their clinical history and physical examination. Physicians must have an index of suspicion, particularly in older white women and in those patients with an atypical esophagitis or stricturing disease, which do not respond to traditional treatment. Currently, there are limited data on esophageal lichen planus patients, and no formal management guidelines for this disease, which all gastroenterologists will see in practice. This article reviews the etiology and histopathology of LP and provides a comprehensive discussion of the clinical features, diagnosis, and management of esophageal disease from the gastroenterologist's perspective. Finally, we address the esophageal complications of LP.

Persistent cutaneous lesion in a child with tyrosinemia: Esomeprazole-induced lichenoid drug eruptions

Lichenoid drug eruptions (LDEs) are among well-recognized adverse reactions that different drugs including Proton-pump inhibitors (PPIs) are associated with. LDEs are rare adverse reaction of PPIs but they should be considered as appropriate management can lead to full resolution. Herein, we report a case of Esomeprazole-induced LDE in a child with tyrosinemia.

Fixed drug eruptions, bullous drug eruptions, and lichenoid drug eruptions

Drug reactions are among the most common reasons for inpatient dermatology consultation. These reactions are important to identify because discontinuation of the offending agent may lead to disease remission. With the rising use of immunomodulatory and targeted therapeutics in cancer care and the increased incidence in associated reactions to these drugs, the need for accurate identification and treatment of such eruptions has led to the development of the "oncodermatology" subspecialty of dermatology. Immunobullous drug reactions are a dermatologic urgency, with patients often losing a significant proportion of their epithelial barrier; early diagnosis is critical in these cases to prevent complications and worsening disease. Lichenoid drug reactions have myriad causes and can take several months to occur, often leading to difficulties identifying the offending drug. Fixed drug eruptions can often mimic other systemic eruptions, such as immunobullous disease and Stevens-Johnson syndrome, and must be differentiated from them for effective therapy to be initiated. We review the clinical features, pathogenesis, and treatment of immunobullous, fixed, and lichenoid drug reactions with attention to key clinical features and differential diagnosis.

Oral Lichenoid Reaction: An Uncommon Side Effect of Rituximab

Oral lichenoid reactions (OLR) can be caused by systemic drug exposure. To the best of our knowledge, this is the second report describing a case of OLR induced by rituximab administration in a patient with a diagnosis of non-Hodgkin B-cell lymphoma. After 5 doses of rituximab, a typical pattern of OLP was identified with bilateral and symmetrical lesions on the buccal mucosa and on the right lingual margin. This temporal relationship suggested a probable association between oral lesions and drug therapy. The clinical diagnosis of a rituximab-induced OLR was confirmed by an incisional biopsy reporting a histopathological result of lichenoid mucositis consistent with oral lichen planus. Because of the increasing use of rituximab, it is necessary to know and recognize this uncommon side effect.

Lichen Planus Pemphigoides: From Lichenoid Inflammation to Autoantibody-Mediated Blistering

Lichen planus pemphigoides (LPP) is a very rare autoimmune sub-epidermal blistering disease associated with lichenoid skin changes. Initially thought to be a mere variant of more common inflammatory dermatoses, particularly Bullous Pemphigoid (BP) or Lichen Planus (LP), a growing body of evidence suggests that it is a disease entity in its own right. In common with a range of autoimmune blistering diseases, including BP, pemphigoid gestationis (PG), mucous membrane pemphigoid (MMP) and linear IgA dermatosis (LAD), a key feature of the disease is the development of autoantibodies against type XVII collagen (COL17). However, accurately establishing the diagnosis is dependent on a careful correlation between the clinical, histological and immunological features of the disease. Therefore, we present an up to date summary of the epidemiology and etiopathogenesis of LPP, before illustrating the predisposing and precipitating factors implicated in the development of the disease. In addition to a selective literature search, we compare reports of potential drug-induced cases of LPP with pharmacovigilance data available via OpenVigil. We subsequently outline the cardinal clinical features, important differential diagnoses and current treatment options. We conclude by demonstrating that an improved understanding of LPP may not only lead to the development of novel treatment strategies for the disease itself, but may also shed new light on the pathophysiology of more common and treatment-refractory autoimmune blistering diseases.

A review and guide to drug-associated oral adverse effects-Oral mucosal and lichenoid reactions. Part 2

Dental practitioners and other health professionals commonly encounter and manage adverse medicine effects that manifest in the orofacial region. Numerous medicines are associated with a variety of oral adverse effects. However, due to lack of awareness and training, these side effects are not always associated with medicine use and are underreported to pharmacovigilance agencies by dentists and other health professionals. This article aims to inform health professionals about the various oral adverse effects that can occur and the most commonly implicated drugs to improve the management, recognition and reporting of adverse drug effects. This article follows on from Part 1; however, the focus here is on lichenoid reactions and oral mucosal disorders including oral aphthous-like ulceration, mucositis and bullous disorders such as drug-induced pemphigus, pemphigoid, Stevens-Johnson syndrome and toxic epidermal necrolysis.

Diagnosis of oral lichen planus: a position paper of the American Academy of Oral and Maxillofacial Pathology

Despite being one of the most common oral mucosal diseases and recognized as early as 1866, oral lichen planus (OLP) is still a disease without a clear etiology or pathogenesis, and with uncertain premalignant potential. More research is urgently needed; however, the research material must be based on an accurate diagnosis. Accurate identification of OLP is often challenging, mandating inclusion of clinico-pathological correlation in the diagnostic process. This article summarizes current knowledge regarding OLP, discusses the challenges of making an accurate diagnosis, and proposes a new set of diagnostic criteria upon which to base future research studies. A checklist is also recommended for clinicians to provide specific information to pathologists when submitting biopsy material. The diagnostic process of OLP requires continued clinical follow-up after initial biopsy, because OLP mimics can manifest, necessitating an additional biopsy for direct immunofluorescence study and/or histopathological evaluation in order to reach a final diagnosis.

The Lichenoid Tissue Reactions of the Oral Mucosa: Oral Lichen Planus and Other Lichenoid Lesions

Lichenoid changes in the oral mucosa can be encountered in a wide range of lesions and can have varied etiologies. Immune-mediated disorders, including lichen planus, mucous membrane pemphigoid, discoid lupus erythematosus, and graft-versus-host disease, can have clinical and histologic overlaps. Lichenoid reactions to dental materials, such as amalgam, or to many systemic drugs are also well documented. Dysplasia of the oral cavity at times can also express a lichenoid histology, which may mask the potentially cancerous component. Proliferative verrucous leukoplakia, an unusual clinical disease, mimics oral lichen planus clinically and requires careful correlation of the clinical and pathologic features.

Reação liquenoide à carbamazepina em mucosa bucal: relato de caso

As reações liquenoides por drogas são mais comuns na pele, mas também podem ocorrer na mucosa bucal. Estas lesões são de difícil diagnóstico por causa de sua semelhança clínica com às do líquen plano oral idiopático. O presente artigo relata um caso de reação liquenoide em mucosa bucal, associado ao uso de carbamazepina, no qual o processo de diagnóstico é enfatizado
