Background: Lichenoid drug eruption (LDE) is an uncommon cutaneous adverse drug reaction, where a variety of drugs used in day-to-day clinical practice have been implicated. Objective: To describe the clinico-demographic characteristics of patients with LDE and to identify the most likely drugs involved. Methods: In this prospective, observational study, consecutive patients with LDE presenting to the dermatology department of a tertiary teaching hospital were included. The clinico-demographic profile of patients with LDE and implicated drugs was noted. Treatment of drug reaction along with outcome was also documented. Naranjo adverse drug reaction probability scale was used for causality assessment of the drug reactions. A thorough literature review on LDE was also undertaken due to the paucity of existing literature. Results: A total of 15 patients (11 males and 4 females) with LDE were evaluated. Their age ranged from 37 to 61 years, with a mean of 51.53 ± 7.59 years. Anti-hypertensive medications (40%) were the most common culprit agent, followed by antitubercular drugs (33.4%), anti-diabetic agents (13.3%), and others (13.3%). The latent period (time from drug initiation to the appearance of a cutaneous eruption) varied from 15 days to 6 months (mean 2.2 months). Cutaneous involvement was generalized in 73.4% and photo-distributed lesions in 26.6%. Drug provocation test was done to identify the culprit drug. According to the Naranjo adverse drug reaction probability scale, one-third of LDEs were “definite,” whereas two-thirds were designated as “probable.” Conclusion: LDE is more common in the elderly population. The latent period is comparatively longer in LDE than in other common drug reactions. Prompt recognition and withdrawal of suspected drug are essential to minimize disease morbidity.

Disseminated superficial actinic porokeratosis (DSAP) is an uncommon skin condition that can be inherited or may occur sporadically with multiple red-brown, thin plaques in a photodistribution. The condition more often affects middle-aged women and is often recalcitrant to therapy. In rare literature reports, systemic medications can trigger exacerbation or promote inflammation in pre-existing lesions of DSAP. We present a novel case of chemotherapy-associated DSAP inflammation in a 66-year-old woman after triple therapy with durvalumab (PD-L1 inhibitor), olaparib (PARP inhibitor) and paclitaxel, showing similarities to primary lichen planus-like eruption from immune checkpoint inhibitors.

Introduction: Lichenoid drug eruption (LDE) is an uncommon cutaneous drug reaction (CDR) that has classically been associated with anti-hypertensive drugs, gold, and penicillamine. Case presentation: We present the case of a 63-year-old woman who developed a pruriginous disseminated dermatosis composed of violaceous polygonal flat-topped papules affecting the flexural aspects of the upper and lower limbs, abdominal flanks, and the lumbar and sacral regions. The lesions started 2 weeks after initiating esomeprazole intake. A histopathological exam of one of the lesions was compatible with LDE. The patient discontinued esomeprazole and was treated with medium potency topical corticosteroids and emollient with full resolution of symptoms. Conclusion: Even though CDRs associated with proton-pump inhibitors (PPI) are relatively common, there are only three reported cases of LDE. We report this case to highlight the importance of considering PPIs as the culprit drug in similar clinical situations. [ABSTRACT FROM AUTHOR]

Context: Lichen planus (LP) is known to be associated with viral infections such as hepatitis B and C, but its association with HIV is rarely reported. Lichenoid drug eruptions have been implicated as the side effects of anti-retroviral therapy. Aims and Objectives: The aim of this study is to study demographics, clinical, histological, and immunological profile of the HIV patients presenting with lichenoid dermatitis. Subjects and Methods: HIV patients presenting with LP such as lesions were evaluated with complete history and physical examination. Demographic profile of patients was studied with features such as age, sex, duration of disease, distribution of the lesions, CD4 count, concomitant medications, associated comorbidities, and response to the treatment. Results: Twenty-one HIV patients presenting with LP such as lesions were studied. Of these, 20 patients had LP and one patient had lichenoid drug reaction. The age of the patient ranged from 40 to 60 years with no sex predilection. The duration of lesions ranged from 15 days to 7 years. Eleven patients had simultaneous cutaneous and oral involvement, five patients had only oral involvement and four patients of LP and one patient of lichenoid drug reaction had only cutaneous lesions. All the patients were on antiretroviral therapy, mainly on lamivudine, zidovudine, and nevirapine. Almost all the patients had CD4 count of more than 250 at the time of presentation. One patient was diagnosed to have lupus erythematosus and LP overlap. Patients were treated with oral medications such as corticosteroids, methotrexate, and dapsone and topical medications such as corticosteroids and calcineurin inhibitors. Conclusions: The appearance of LP such as lesions in HIV patients is a rare occurrence with 11 cases of LP reported till date. Our case series of 20 patients will throw light on possible etiology and difficulties in the management of LP such as lesions in HIV patients. [ABSTRACT FROM AUTHOR]

Abstract 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.

Adalimumab, an anti-tumor necrosis factor-α (TNF-α), is widely prescribed for many autoimmune diseases and chronic inflammatory skin diseases such as hidradenitis suppurative, psoriasis, etc. We report a case of lichenoid drug eruption secondary to adalimumab, a rare side effect, in a 62-year-old female with ulcerative colitis. The skin eruption appeared two weeks after initiating adalimumab. A skin biopsy was taken, and the histopathological findings correlated with a lichenoid drug eruption. Although rare, drug-induced lichen planus has been associated with adalimumab. Early recognition and a high index of suspicion are key in the prompt management of these cases. The discontinuation of adalimumab must be carefully weighed against its therapeutic benefits, as the discontinuation might trigger a severe form of inflammation in the primary autoimmune disease being treated. Extreme caution, early intervention, and a multidisciplinary approach are best for the overall well-being and optimal care of the individual., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Trimebutine is a spasmolytic agent with antimuscarinic effects that is used for the treatment of irritable bowel syndrome (IBS) and lower gastrointestinal tract motility disorders. Lichenoid drug eruptions (LDE) to trimebutine maleate have not been previously reported. Here we present the case of a 50-year-old male patient who developed an extensive lichenoid eruption on his upper and lower extremities and trunk 4 weeks after starting treatment with trimebutine maleate 300 mg once daily for IBS. Two months after discontinuation of the drug and administration of topical treatment with emollients and corticosteroids, the LDE cleared completely with no recurrence. The diagnosis of LDE due to trimebutine was made, based upon the clinical features resembling lichen planus, the histological findings of interface dermatitis, the evidence of a temporal relationship between drug intake and the development of skin lesions, and resolution upon discontinuation of the drug. To the best of the authors’ knowledge, LDE following trimebutine maleate intake has not been previously reported. Management of trimebutine-induced LDE includes withdrawal of the causative agent and treatment with potent topical corticosteroids.

Lichenoid drug eruption is characterized by multiple discrete violaceous shiny papules often becoming confluent. It is a common benign adverse drug reaction and has been extensively described in the literature with various drugs. Here, we report an unusual presentation of lichenoid drug eruption in the form of generalized exfoliative dermatitis with hair loss in a patient of human immunodeficiency virus infection due to isoniazid.

Pertuzumab and trastuzumab are monoclonal antibody inhibitors targeting human epidermal growth factor receptor 2 (HER‐2) and are increasingly being utilised in the management of HER2‐positive breast cancer, having been demonstrated to improve progression‐free survival in conjunction with docetaxel. We present a rare presentation of a lichenoid drug eruption, in an annular atrophic variant, in a 35‐year‐old woman after initiation of HER2‐inhibitor (pertuzumab and trastuzumab) therapy for metastatic breast cancer.

3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) are generally safe and well-tolerated drugs that are extensively used for the primary and secondary prevention of atherosclerotic cardiovascular events. Muscle and liver adverse reactions are the best recognized, while cutaneous side effects are exceedingly rare. We present the case of a 65-year-old woman with severe hypercholesterolemia, who developed generalized erythematous cutaneous lesions with pruritus, resembling lichen planus, months after starting treatment with simvastatin. The symptoms disappeared on withdrawal of simvastatin and reappeared within 3 months upon rechallenge with rosuvastatin. In addition to describing a rare adverse effect of statins, the authors also discuss the nutraceutical approach to the management of a statin-intolerant patient.

Cutaneous adverse reactions are a common complication of anti-retroviral therapy. Tenofovir is a newer anti-retroviral drug belonging to the nucleotide reverse transcriptase inhibitor group. Systemic adverse effects like nausea, vomiting, diarrhea, hepatotoxicity and renal toxicity are common with tenofovir but cutaneous adverse effects are rare. Lichenoid drug eruptions are a common adverse effect seen with a large variety of drugs including antimalarials, antihypertensives, nonsteroidal anti-inflammatory drugs and diuretics. Lichenoid drug eruption is a rare cutaneous adverse effect of tenofovir with only a single case reported till date. Here, we report a case of tenofovir induced lichenoid drug eruption in a 54-year-old human immunodeficiency virus affected male who presented with generalized lichenoid eruption after 6 weeks of initiation of tenofovir and complete clearance on cessation of the drug.

Imatinib mesylate (IM), an anticancer drug, has been widely used to treat chronic myeloid leukemia (CML), gastrointestinal stromal tumors (GIST), and dermato-fibrosarcoma protuberans. Cutaneous reactions to IM have been reported to occur in varying number of patients in different case series. Non-lichenoid cutaneous reactions secondary to IM have been well-documented in the literature and are the commonest non-hematologic adverse reactions associated with its use. Lichenoid drug eruption (LDE) associated with IM therapy has rarely been reported in the literature. A case of a generalized LDE associated with IM therapy has been described here for its rarity and interesting clinical presentation. As the clinical usage of IM is increasing, one might expect an increasing number of similar patients in the future. It is thus important to realize the potential of IM to produce LDE and to differentiate this entity from idiopathic lichen planus. In the present article, the reports of IM-associated LDE, described in the PubMed and Medline database (in English language literature), have also been reviewed.

Introduction: Practically all physicians encounter a diverse range of suspected cutaneous adverse drug reactions (CADRs) in their daily clinical practice. The skin and mucosa are the most often encountered areas for the early presentation of numerous adverse drug reactions. Cutaneous adverse drug reactions are classified as benign or severe. The clinical manifestations of drug eruptions can range from mild maculopapular exanthema to severe cutaneous adverse drug reactions (SCARs)., Objective: To determine the varied clinical and morphological presentations of CADRs and to identify the culprit drug and common drugs causing CADRs., Materials and Methods: Patients with clinical features suspected of CADRs presenting to the outpatient department (OPD) of dermatology, venereology, and leprosy (DVL) between December 2021 to November 2022 at Great Eastern Medical School and Hospital (GEMS), Srikakulam, Andhra Pradesh, India, were considered for the study. This was a cross-sectional, observational study. The patient's clinical history was taken in detail. This included chief complaints (symptoms, site of onset, duration, drug history, latency time between drug administration and the appearance of cutaneous lesions), family history, associated diseases, the morphology of lesions, and mucosal examination. Upon drug discontinuation, improvement in cutaneous lesions and systemic features were noted. A complete general examination, systemic examination, dermatological tests, and mucosal examination were performed., Results: A total of 102 patients were involved in the study, of whom 55 were males and 47 were females. The male-to-female ratio was 1.17:1, with a slight male majority. The most common age group was 31 to 40 years for both males and females. Itching was the predominant complaint in 56 patients (54.9%). The mean latency period was shortest in urticaria (2.13+/- 0.99 hours) and longest in lichenoid drug eruption (4.33+/- 3.93 months). Most patients developed symptoms after a week of taking the drug (53.92%). A history of similar complaints was present in 38.23% of patients. Analgesics and antipyretics (39.2%) were the most common culprit drugs followed by antimicrobials (29.4%). Among analgesics and antipyretics, aceclofenac (24.5%) was the commonest culprit drug. Benign CADRs were observed in 89 patients (87.25%), and severe cutaneous adverse reactions (SCARs) were observed in 13 patients (12.74%). The common CADRs presented were drug-induced exanthem (27.4%). Imatinib-induced psoriasis vulgaris and lithium-induced scalp psoriasis were observed in one patient each. Severe cutaneous adverse reactions were observed in 13 patients (12.74%). Anticonvulsants, nonsteroidal anti-inflammatory drugs (NSAIDs), and antimicrobials were the culprit drugs for SCARs. Eosinophilia was present in three patients, deranged liver enzymes was present in nine patients, a deranged renal profile was present in seven patients, and death occurred in one patient with toxic epidermal necrolysis (TEN) of SCARs., Conclusion: Before prescribing any drug to a patient, a detailed drug history and family history of drug reactions need to be obtained. Patients should be advised to avoid over-the-counter usage of medications and self-administration of drugs. If adverse drug reactions occur, it is advised to avoid readministration of the culprit drug. Drug cards must be prepared and given to the patient, mentioning the culprit drug as well as the cross-reacting drugs., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Ashifha et al.)

Out of a total of 1147 patients on antihypertensive drugs, 23 (2.04%) developed adverse cutaneous drug reactions (ACDR). The commonest antihypertensive drug group causing ACDR was beta-blockers of which atenolol was the commonest culprit. The second most common group was calcium channel blockers with amlodipine as the commonest offender. The most common patterns of ACDR observed included urticaria followed by lichenoid drug eruption (LDE). We noted 2 new patterns of reactions; (i) one patient developed brownish blue pigmentation of nails while on atenolol for 3 years, which resolved in 4 months after withdrawal and (ii) another patient on amlodipine for 8 years developed Schamberg′s like purpuric pigmentation, which resolved on withdrawal of drug within 3 months. These findings have not been reported in the literature earlier. This study is presented for paucity of Indian data on ACDR due to antihypertensive drugs, and remarkable advancement in area of cardiovascular and antihypertensive pharmacology and a large number of population taking antihypertensive drugs.

Drug-induced lichen planus has been induced by antibiotics, anticonvulsants, antidiabetics, antimalarials, antitubercular drugs, antihypertensives, psychiatric drugs, chemotherapeutic agents, diuretic, heavy metals, NSAIDs, etc. Terbinafine, an antifungal agent, is widely used for dermatophyte infections and onychomycosis. Cutaneous adverse effects of terbinafine are rarely reported. Here, we report a case of terbinafine-induced lichenoid drug eruption in a 22-year-old who presented with generalized lichenoid eruption 2 weeks after terbinafine initiation of. The body and lip cleared completely after 8 weeks of drug withdrawal; nail change cleared after 12 weeks. [ABSTRACT FROM PUBLISHER]

Lichenoid drug eruptions have been previously reported. Here, we report two cases of bilateral oral lichenoid lesions on the buccal mucosa that appeared during low-dose methotrexate treatment for rheumatoid arthritis. The first case was a 71-year-old woman on methotrexate for rheumatoid arthritis, who presented with bilateral oral ulceration on the buccal mucosa. On examination, erythematous ulcers surrounded by white plaques and striae were seen. Oral lichen planus was suspected clinically but topical steroids were ineffective. However, an improvement was observed after reducing the dose of methotrexate, and epithelialization occurred after drug cessation. Reintroduction of methotrexate resulted in recurrence. Histopathological examination of a biopsy taken from the oral mucosa confirmed the lesion as an oral lichenoid lesion. The second case was an 87-year-old woman on methotrexate for rheumatoid arthritis, who presented with pain of the oral mucosa. On examination, ulceration, erythema, and white plaques were observed bilaterally on the buccal mucosa. The disease was diagnosed clinically as oral lichen planus but no improvement was seen after topical steroid treatment. The lesions disappeared after discontinuation of methotrexate. This is the first report of oral lichenoid lesions due to methotrexate. [ABSTRACT FROM AUTHOR]

Ophthalmic preparations are commonly used medications that have been implicated in causing a variety of dermatological reactions. These reactions include toxic epidermal necrolysis, anaphylaxis, fixed drug eruption, lichenoid drug reaction and local and systemic contact dermatitis. This article reviews the dermatological and systemic reactions associated with ophthalmic preparation use and highlights the need for a thorough medication history to be done for all patients presenting with a suspected drug reaction.
