Oral lichen planus: comparative efficacy and treatment costs-a systematic review.

OBJECTIVE: To compare the reported efficacy and costs of available interventions used for the management of oral lichen planus (OLP). MATERIALS AND METHODS: A systematic literature search was performed from database inception until March 2021 in MEDLINE via PubMed and the Cochrane library following PRISMA guidelines. Only randomized controlled trials (RCT) comparing an active intervention with placebo or different active interventions for OLP management were considered. RESULTS: Seventy (70) RCTs were included. The majority of evidence suggested efficacy of topical steroids (dexamethasone, clobetasol, fluocinonide, triamcinolone), topical calcineurin inhibitors (tacrolimus, pimecrolimus, cyclosporine), topical retinoids, intra-lesional triamcinolone, aloe-vera gel, photodynamic therapy, and low-level laser therapies for OLP management. Based on the estimated cost per month and evidence for efficacy and side-effects, topical steroids (fluocinonide > dexamethasone > clobetasol > triamcinolone) appear to be more cost-effective than topical calcineurin inhibitors (tacrolimus > pimecrolimus > cyclosporine) followed by intra-lesional triamcinolone. CONCLUSION: Of common treatment regimens for OLP, topical steroids appear to be the most economical and efficacious option followed by topical calcineurin inhibitors. Large-scale multi-modality, prospective trials in which head-to-head comparisons interventions are compared are required to definitely assess the cost-effectiveness of OLP treatments.

Hypertrophic lichenoid dermatitis immune-related adverse event during combined immune checkpoint and exportin inhibitor therapy: A diagnostic pitfall for superficially invasive squamous cell carcinoma.

Immune checkpoint inhibitors (ICIs) for cancer treatment have revolutionized the field of medicine. However, an unintended but frequent consequence of ICI therapy is the development of cutaneous immune-related adverse events (irAEs), such as lichenoid dermatitis irAEs (LD-irAEs). The hypertrophic variant of LD-irAE may be a diagnostic challenge since it can mimic superficially invasive squamous cell carcinoma (SCC). A 79-year-old woman with metastatic melanoma who began treatment with an ICI-pembrolizumab-plus exportin-1 (XPO1) inhibitor presented after 1 month of therapy with symmetrical violaceous papules coalescing into plaques and with two nodules of the bilateral dorsal hands. Biopsy of the nodules revealed an actinic keratosis and atypical epidermal proliferation concerning for SCC. However, in the ensuing 3 weeks, the patient developed multiple new erythematous, violaceous, and scaly macules and papules, some coalescing into plaques on the extremities. Biopsies of these lesions revealed exuberant irregular epidermal hyperplasia with hypermaturation and lichenoid infiltrate concentrated at the base of the elongated, broadened rete ridges, consistent with hypertrophic LD-irAE. Treatment included topical fluocinonide ointment, intralesional triamcinolone injections and oral acitretin. Distinguishing hypertrophic LD-irAE and SCC can be challenging since both entities share histopathologic features; thus, correlation with clinical presentation is essential for diagnosis and optimal patient management.

Successful management of pediatric oral pemphigus vulgaris with topical corticosteroid monotherapy.

Pemphigus vulgaris (PV) is an autoimmune intraepithelial bullous disease that affects the skin and mucous membranes. Typically, the management of PV is challenging, with systemic corticosteroids being the mainstay of treatment. We describe the case of a 14-year-old girl who was diagnosed with oral PV and successfully treated with topical corticosteroids alone. This case details a pediatric mucosal PV case successfully managed solely with topical corticosteroids.

A Pilot Study Characterizing Factors in Adherence to Cutaneous Lupus Treatment.

Cutaneous lupus erythematosus (CLE) is an autoimmune skin disease that manifests as scarring, dyspigmentation, erythema, and pain. Topical corticosteroids are a mainstay of treatment. Irritation, messiness, and tediousness may deter use. Thus, nonadherence, rather than nonresponse, can result in treatment failure. Prior adherence studies were limited to systemic lupus erythematosus. We performed a single-center, open-label pilot study to assess adherence to topical medication in patients with CLE. CLE adherence to topical medications is suboptimal and declines over time. Shorter treatment duration and greater patient perception of disease severity may contribute to higher adherence. Improving adherence to existing treatments could be as or more valuable than new therapies for the disease.

Drugs for discoid lupus erythematosus.

BACKGROUND: Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE. OBJECTIVES: To assess the effects of drugs for discoid lupus erythematosus. SEARCH METHODS: We updated our searches of the following databases to 22 September 2016: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We also searched five trials databases, and checked the reference lists of included studies for further references to relevant trials. Index Medicus (1956 to 1966) was handsearched and we approached authors for information about unpublished trials. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) of drugs to treat people with DLE in any population group and of either gender. Comparisons included any drug used for DLE against either another drug or against placebo cream. We excluded laser treatment, surgery, phototherapy, other forms of physical therapy, and photoprotection as we did not consider them drug treatments. DATA COLLECTION AND ANALYSIS: At least two reviewers independently extracted data onto a data extraction sheet, resolving disagreements by discussion. We used standard methods to assess risk of bias, as expected by Cochrane. MAIN RESULTS: Five trials involving 197 participants were included. Three new trials were included in this update. None of the five trials were of high quality.'Risk of bias' assessments identified potential sources of bias in each study. One study used an inappropriate randomisation method, and incomplete outcome data were a concern in another as 15 people did not complete the trial. We found most of the trials to be at low risk in terms of blinding, but three of the five did not describe allocation concealment.The included trials inadequately addressed the primary outcome measures of this review (percentage with complete resolution of skin lesions, percentage with clearing of erythema in at least 50% of lesions, and improvement in patient satisfaction/quality of life measures).One study of fluocinonide cream 0.05% (potent steroid) compared with hydrocortisone cream 1% (low-potency steroid) in 78 people reported complete resolution of skin lesions in 27% (10/37) of participants in the fluocinonide cream group and in 10% (4/41) in the hydrocortisone group, giving a 17% absolute benefit in favour of fluocinonide (risk ratio (RR) 2.77, 95% CI 0.95 to 8.08, 1 study, n = 78, low-quality evidence). The other primary outcome measures were not reported. Adverse events did not require discontinuation of the drug. Skin irritation occurred in three people using hydrocortisone, and one person developed acne. Burning occurred in two people using fluocinonide (moderate-quality evidence).A comparative trial of two oral agents, acitretin (50 mg daily) and hydroxychloroquine (400 mg daily), reported two of the outcomes of interest: complete resolution was seen in 13 of 28 participants (46%) on acitretin and 15 of 30 participants (50%) on hydoxychloroquine (RR 0.93, 95% CI 0.54 to 1.59, 1 study, n = 58, low-quality evidence). Clearing of erythema in at least 50% of lesions was reported in 10 of 24 participants (42%) on acitretin and 17 of 25 (68%) on hydroxychloroquine (RR 0.61, 95% CI 0.36 to 1.06, 1 study, n = 49, low-quality evidence). This comparison did not assess improvement in patient satisfaction/quality of life measures. Participants taking acitretin showed a small increase in serum triglyceride, not sufficient to require withdrawal of the drug. The main adverse effects were dry lips (93% of the acitretin group and 20% of the hydroxychloroquine group) and gastrointestinal disturbance (11% of the acitretin group and 17% of the hydroxychloroquine group). Four participants on acitretin withdrew due to gastrointestinal events or dry lips (moderate-quality evidence).One trial randomised 10 people with DLE to apply a calcineurin inhibitor, pimecrolimus 1% cream, or a potent steroid, betamethasone 17-valerate 0.1% cream, for eight weeks. The study reported none of the primary outcome measures, nor did it present data on adverse events.A trial of calcineurin inhibitors compared tacrolimus cream 0.1% with placebo (vehicle) over 12 weeks in 14 people, but reported none of our primary outcome measures. In the tacrolimus group, five participants complained of slight burning and itching, and for one participant, a herpes simplex infection was reactivated (moderate-quality evidence).Topical R-salbutamol 0.5% cream was compared with placebo (vehicle) over eight weeks in one trial of 37 people with DLE. There was a significant improvement in pain and itch in the salbutamol group at two, four, six, and eight weeks compared to placebo, but the trial did not record a formal measure of quality of life. None of the primary outcome measures were reported. Changes in erythema did not show benefit of salbutamol over placebo, but we could not obtain from the trial report the number of participants with clearing of erythema in at least 50% of lesions. There were 15 events in the placebo group (experienced by 12 participants) and 24 in the salbutamol group (experienced by nine participants). None of the adverse events were considered serious (moderate-quality evidence). AUTHORS' CONCLUSIONS: Fluocinonide cream may be more effective than hydrocortisone in clearing DLE skin lesions. Hydroxychloroquine and acitretin appear to be of equal efficacy in terms of complete resolution, although adverse effects might be more frequent with acitretin, and clearing of erythema in at least 50% of lesions occurred less often in participants applying acitretin. Moderate-quality evidence found adverse events were minor on the whole. There is not enough reliable evidence about other drugs used to treat DLE. Overall, the quality of the trials and levels of uncertainty were such that there is a need for further trials of sufficient duration comparing, in particular, topical steroids with other agents.

Molluscum Contagiosum-Like Presentation of Langerhans Cell Histiocytosis: A Case and Review.

Langerhans cell histiocytosis (LCH) is a rare disorder characterized by clonal proliferation of Langerhans cells in the skin. A molluscum-like presentation of cutaneous LCH is rare but important to consider for examination and management. We present an atypical molluscum-like LCH case and review the literature for common features of this unusual presentation.

Urticarial hypersensitivity reaction caused by temozolomide.

Temozolomide is an oral alkylating agent approved for the treatment of glioblastoma and anaplastic astrocytoma, and is currently under clinical investigation for the treatment of brain metastases from a variety of cancers. Temozolomide is well tolerated, and the reported dermatologic side effects of this medication are limited. Here, the authors report the first case of an urticarial hypersensitivity reaction induced by temozolomide. As this drug will likely be increasingly utilized in the near future, it is important to be aware of its potential to cause adverse cutaneous manifestations.

Improvement in treatment adherence with a 3-day course of fluocinonide cream 0.1% for atopic dermatitis.

Variations in adherence may cause variations in treatment outcomes with topical corticosteroid therapy for atopic dermatitis. An intensive short course of outpatient treatment may promote good adherence and provide a high level of efficacy. The purpose of this study was to assess the efficacy, tolerability, and adherence to short-term treatment with fluocinonide cream 0.1% in the treatment of atopic dermatitis. Twenty participants with mild to severe atopic dermatitis were instructed to use fluocinonide cream 0.1% twice daily for 3 consecutive days for a total of 6 doses. Disease severity was assessed at baseline, day 3, day 7, and day 14. Electronic monitoring was used to measure adherence to treatment. Median adherence to treatment over the 3-day period was 100%. By day 14, the median visual analog scale (VAS) of pruritus and eczema area and severity index (EASI) scores improved from baseline by 79% and 76%, respectively. By the end of the study period, 11 participants had investigator global assessment (IGA) scores of clear or almost clear. The absolute degree of improvement was proportional to baseline disease severity. Short-term treatment with fluocinonide cream 0.1% for atopic dermatitis was well-tolerated and resulted in significant disease improvement (P < .001). Participants were highly adherent to the 3-day treatment regimen. Efforts to improve adherence may be valuable approaches for treating recalcitrant atopic dermatitis.

Patients preferences for different corticosteroid vehicles are highly variable.

Introduction: Topical corticosteroids, available in an array of vehicles are used to control a variety of inflammatory skin diseases. Patients preferences for different vehicles may affect their willingness to use treatment. We assess corticosteroid vehicle preference and potential impact of topical characteristics on adherence and quality of life in patients with psoriasis.Methods: Subjects with psoriasis were recruited from Wake Forest University Dermatology Clinic. Subjects sampled desoximetasone 0.25% spray, betamethasone valerate 0.1% cream, triamcinolone acetonide 0.1% ointment, fluocinonide 0.05% gel, betamethasone valerate 0.1% lotion, clobetasol propionate 0.05% foam, and fluocinonide 0.05% solution in a predetermined randomized order. Subjects completed a Vehicle Preference Measure, Determinants of Adherence Measure, and a Determinants of Quality of Life Measure.Results: Patients preferences for the various products were highly variable. Regarding Determinants of Adherence, patients perception of absorption of the medication was ranked as 'quite important/extremely important' by 85% of total subjects. A majority of patients rated medication side effects as 'quite important/extremely important' when asked to consider topical characteristics effect on quality of life.Discussion: There was wide variation in patient preference for topical medication vehicles used for treating psoriasis. Several vehicle characteristics were considered important to adherence. Given the marked variation in vehicle preference, topical treatment should be individualized according to patients preferences.

Drugs for discoid lupus erythematosus.

BACKGROUND: Discoid lupus erythematosus is a chronic form of cutaneous (skin) lupus which can cause permanent scarring if treatment is inadequate. Many drugs have been used to treat this disease and some of these are potentially very toxic. OBJECTIVES: To assess the effects of drugs for discoid lupus erythematosus. SEARCH STRATEGY: In June 2009 we updated our searches of the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 2, 2009), MEDLINE, EMBASE, LILACS, and online ongoing trials registers. The reference lists of relevant reviews were searched. Index Medicus (1956 to 1966) was handsearched and we approached authors for information about unpublished trials. SELECTION CRITERIA: We included all randomised trials of drugs to treat people with discoid lupus erythematosus. Drugs included in the search were azathioprine, chloroquine, clofazimine, corticosteroids, (oral and topical), dapsone, gold, interferon alpha-2a, methotrexate, phenytoin, retinoids, sulphasalazine, thalidomide, topical calcineurin blockers (pimecrolimus and tacrolimus), and biological agents (etanercept, efalizimab, infliximab, and rituximab). DATA COLLECTION AND ANALYSIS: Two reviewers independently examined each retrieved study for eligibility. MAIN RESULTS: Two trials involving 136 participants were included. No new trials were included in this update.In a cross-over study of 12 weeks duration, fluocinonide 0.05% cream (a potent topical corticosteroid), appeared to be better than hydrocortisone 1% cream (a mild corticosteroid) when the first arm of the trial involving 78 participants was analysed at 6 weeks. Clearing or excellent improvement was seen in 27% of people using fluocinonide and in 10% of those using hydrocortisone, giving a 17% absolute benefit in favour of fluocinonide (95% CI 0.0 to 0.34, NNT (Number needed to treat) 6).In the second trial, acitretin (50mg/day) was compared with hydroxychloroquine (400mg/day) in 58 people in a parallel trial of 8 weeks duration. There was marked improvement or clearing in 46% of people using acitretin and in 50% of those on hydroxychloroquine but there was no significant difference between the 2 interventions. The adverse effects were more frequent and more severe in the acitretin group. In this trial clearing of erythema was measured and found to be better in the hydroxychloroquine group (RR 0.61, 95% CI 0.36 to 1.06). AUTHORS' CONCLUSIONS: Fluocinonide cream may be more effective than hydrocortisone in treating people with discoid lupus erythematosus. Hydroxychloroquine and acitretin appear to be of equal efficacy, although adverse effects are more frequent and more severe with acitretin. There is not enough reliable evidence about other drugs used to treat discoid lupus erythematosus.

The efficacy of three class I topical synthetic corticosteroids, fluocinonide 0.1% cream, clobetasol 0.05% cream and halobetasol 0.05% cream: a Scholtz-Dumas bioassay comparison.

BACKGROUND: This study compared the efficacy of a novel, topical class I synthetic, 0.10% fluocinonide corticosteroid with two other class I corticosteroids and placebo for the treatment of plaque psoriasis. METHODS: A 0.5 gram dose of fluocinonide 0.1% cream, clobetasol propionate 0.05% cream, halobetasol propionate 0.05% cream, and placebo ointment were applied to test sites on one psoriatic plaque per patient (n=5). Test sites were outlined according to the Scholtz-Dumas bioassay. Test sites were assessed by a blinded evaluator (1 = psoriasis worsened to 5 = psoriasis clear or almost clear), cleaned and medications were reapplied on days 3, 5, 7, 10 and 12. RESULTS & CONCLUSION: The three class I corticosteroid products were comparably effective, numerically and statistically, in clearing the psoriatic plaques. Upon completion of treatment, 60-80% of active-treated sites were clear or almost clear of psoriasis compared to zero with the placebo.

Case report: Fluocinonide-induced perioral dermatitis in a patient with psoriasis.

Topical corticosteroids are the primary treatment for psoriasis. A patient with psoriasis being treated with topical fluocinonide for lesions on the extremities developed an erythematous facial eruption consistent with perioral dermatitis. When topical agents are applied, they often end up in unintended areas. The potential for drug-induced perioral dermatitis should be considered in psoriasis patients treated with potent topical corticosteroids.

Bullous mastocytosis: report of a patient and a brief review of the literature.

We report a 6-month-old male infant who presented to the pediatric dermatology clinic at Wake Forest University Baptist Medical Center with a generalized bullous eruption since 3 months of age. A sepsis work up was performed at an outside hospital before presentation and did not reveal any evidence of systemic infection. Clinical presentation revealed a well-nourished, appropriate-for-age, 6-month-old boy with multiple tense bullae, some in a "string of pearls" arrangement, on the bilateral upper extremities and trunk. Multiple erosions were also noted. Laboratory evaluation revealed a normal complete blood count. Polymerase chain reaction was negative for herpes simplex virus types I and II. Histologic sections demonstrated a large space of separation between the epidermis and dermis which was filled by a monomorphous infiltrate composed of round to oval cells with centrally placed nuclei, consistent with mast cells. Leder and C-Kit stains were strongly positive, confirming the diagnosis of bullous mastocytosis. Treatment included fluocinonide 0.05% cream and tacrolimus 0.1% ointment to active lesions and silver sulfadiazine 1% cream to erosions. Improvement was noted during follow-up examination.

Reticulated phototoxic eruption in a patient on long-term diltiazem therapy.

Diltiazem hydrochloride is a commonly prescribed medication in the treatment of cardiovascular disease. A case of diltiazem-induced hyperpigmentation in a patient after significant sun exposure is reported. The morphological appearance was reticulated and slate-gray to blue in color. The pathogenesis of the hyperpigmentation is discussed and possible treatment options are reviewed.

CO2 laser evaporation of oral lichen planus.

Oral lichen planus is a relatively common disease of the oral mucosa. The buccal mucosa and lateral border of the tongue are mostly involved, although the condition can occur anywhere in the oral cavity. The erosive type in particular can cause spontaneous pain during eating. In the period from 1975 to 2003, a group of 21 patients with 39 lesions of oral lichen planus which caused pain, even after conservative therapy, were treated with CO2 laser evaporation. During a follow-up period of 1-18 years (mean 8 years) 21 patients were pain free (85%) and 6 patients (15%) experienced painful recurrence after treatment. After retreatment with CO2 laser evaporation there were no complaints of pain. Among the many treatments available, high-potency topical corticosteroids remain the most consistent and effective. In patients whose condition is unresponsive to topical corticosteroids, CO2 laser evaporation can cause long-term remission of symptoms, and may even be the treatment of first choice in patients suffering from painful oral lichen planus.

Subcorneal pustular dermatosis (Sneddon-Wilkinson disease) occurring in association with nodal marginal zone lymphoma: a case report.

Sneddon-Wilkinson disease or subcorneal pustular dermatosis (SPD) is a rare, benign inflammatory skin disorder of unknown etiology. SPD is associated with various systemic disorders, including immunoglobinopathies and lymphoproliferative disorders. The relationship between SPD and immune dysfunction is unlikely to be incidental, although it still remains a mystery whether the associated gammopathies are primary or secondary to the pathogenesis of the disease. Herein, we report the first case of SPD in association with marginal zone lymphoma.

A case of disseminate and recurrent infundibulofolliculitis responsive to treatment with topical steroids.

Disseminate and recurrent infundibulofolliculitis (DRIF) is an uncommon pruritic follicular eruption of unknown etiology that is predominantly seen in black men. This condition tends to affect the trunk and upper extremities and is usually unresponsive to local and systemic treatment. Recently, several investigators have reported successful treatment with isotretinoin. Herein, we report a case of a patient with disseminate and recurrent infundibulofolliculitis who was successfully treated with potent topical corticosteroids.

Left-sided eruption on a child: case study.

Asymmetric periflexural exanthema of childhood is a benign, self-limiting disease of unknown origin. Patients generally present a few weeks after a viral-like prodrome with erythematous macules and papules within flexural spaces followed by centrifugal spread. Treatment focuses on alleviating symptoms of pruritus.

Acute generalized exanthematous pustulosis: clinical characteristics, etiologic associations, treatments, and outcomes in a series of 28 patients at Mayo Clinic, 1996-2013.

BACKGROUND: Acute generalized exanthematous pustulosis (AGEP) is a rare skin condition typically caused by medications. The objective of this study was to examine the clinical features, causes, and outcomes of AGEP at a sole tertiary care center. METHODS: A retrospective review of patients with AGEP (European Study of Severe Cutaneous Adverse Reactions score of ≥ 5) seen at Mayo Clinic (Rochester, MN, USA) between January 1, 1996, and December 31, 2013, was conducted. RESULTS: Of 28 patients (mean age at onset: 56 years), 17 (61%) were women. The development of AGEP was attributed to medications in 25 patients (89%), with clindamycin the most common culprit (six patients). Three patients (11%) had mucous membrane involvement, and 21 (75%) showed systemic involvement. Ten patients (36%) received systemic corticosteroids for treatment of AGEP. Skin findings resolved within 15 days in 26 patients (93%) (mean time to resolution: 7.6 days). In three patients (11%), generalized skin eruptions or dermatitis developed weeks to months after the resolution of AGEP. Twenty-four patients (86%) had a personal history of drug reactions before the development of AGEP. CONCLUSIONS: A previous history of drug reactions and clindamycin causation were more common in the present cohort than in prior reports. A small subset of patients experienced new-onset non-AGEP skin eruptions within a few months of the resolution of AGEP.
