RESUMEN
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.
RESUMEN
INTRODUCTION: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR) are linked with side effects involving skin and mucosa. Herein, we present a unique case of oral lichenoid drug eruption (LDE) in a patient treated with osimertinib. CASE REPORT: A 75-year-old woman was diagnosed with metastatic EGFR-mutated lung adenocarcinoma, and started on osimertinib 80â mg PO daily. At 24 months of therapy, the patient developed a painful, red, and white striated oral lesion involving the left buccal mucosa and the adjacent buccal aspect of gingivae. Biopsy showed oral LDE. Causality assessment between osimertinib and the oral LDE via Naranjo Adverse Drug Reaction probability scale revealed a score of 5. MANAGEMENT AND OUTCOME: Osimetinib discontinuation was not felt to be in the best interest of the patient. Therefore, diphenhydramine HCL mouthwash every 6â h PRN (before meals) was started. Spicy and hot foods were discontinued. At a four-week follow-up visit, the patient reported moderate improvement in her symptoms. CONCLUSION: Oral LDEs are considered premalignant lesions as they can transform into squamous cell carcinoma; therefore, regular follow-up is needed. Awareness of this potential side effect of osimertinib would also prevent unnecessary (and potentially costly) work-up and lead to its prompt diagnosis and treatment.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.

Antihypertensive agents such as spironolactone have been reported to cause lichenoid drug eruptions. Eruptive keratoacanthomas (KA), considered to be well-differentiated squamous cell carcinoma (SCC), may develop in the setting of such lichenoid reactions. Thus, definitive treatment is imperative. This case report describes a patient on spironolactone who developed a lichenoid drug eruption followed by eruptive KAs and SCC. The treatment approach used systemic methotrexate. While most treatment regimens for widespread eruptive KA/SCC employ intralesional methotrexate, this case demonstrated the utility of its systemic counterpart. This may have also facilitated the resolution of the patient's lichenoid eruption. There are only three other reports in the literature describing a spironolactone-induced lichenoid drug eruption. Further investigations are needed to evaluate the adverse cutaneous effects of spironolactone as well as the efficacy of systemic methotrexate in treating patients with a significant number of SCCs arising from lichenoid drug eruptions.
RESUMEN
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.
RESUMEN
Pembrolizumab is an immune checkpoint inhibitor approved for use in many cancer types such as non-small cell lung cancer (NSCLC), metastatic melanoma, head and neck cancers, hepatocellular carcinoma, and renal cell carcinoma. There are many reported cases of patients on immunotherapy who have discontinued treatment due to the development of immune-related adverse effects (irAE). Recognition of the histopathologic patterns of dermatologic toxicities due to immunotherapy will become increasingly important for ensuring appropriate management and optimal patient care. Here, we present a case of a 72-year-old man with metastatic carcinoma of unknown primary origin treated with pembrolizumab who developed an immune-related cutaneous adverse event (ircAE) in the form of lichenoid dermatitis.
RESUMEN
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.

BACKGROUND: A rare type of cutaneous adverse drug reaction (CADR), lichenoid drug eruption (LDE), can be associated with ethambutol. CASE REPORT: A 60-year-old woman with spinal tuberculosis received multiple anti-TB medications and developed rashes after 3 months of the treatments. A skin biopsy from the posterior auricular area confirmed lichenoid dermatitis, and the Naranjo causality assessment indicated ethambutol as a probable cause of LDE in the patient. The rashes slowly improved after discontinuation of ethambutol. Unfortunately, the residual of brown hyperpigmentation on the body still persisted for over 16 months. CONCLUSION: The medications were reduced to isoniazid 300 mg/day and rifampicin 450 mg /day as planned for another 3 months. This case report points out the essentials of early recognition of ethambutol LDE by health care professionals.

The differential diagnosis between lichenoid drug eruption (LDE) and lichen planus (LP) is difficult due to similar clinical and histological signs but important for treatment and prognosis. The purpose of this study was to propose the new diagnosis method for differentiate LDE from LP. During 2015-2018, 20 patients with confirmed LDE, 13 patients with LP and 134 controls were examined and treated at the Lenoblcenter. All enrolled patients were underwent the injection of 0.5 mL of the 2% lidocaine solution by insulin syringe into the papule with following histological examination. The formation of a blister (bulla) at the site of injection was considered a positive test result. Among LDE, 18 of 20 patients were found positive for developing blister (bulla) and two results were questionable. In 12 of 13 LP patents, bulla on the site of injection was not identified and the result of one patient was nonspecific. All control patients were negative for the proposed test. The histological sections showed that the bulla has corresponded to the separation of the epidermis from the dermis. Intracutaneous injection of 0.5 mL of lidocaine into the papule is an easy highly specific and sensitive method to differentiate LDE from LP.

INTRODUCTION: Lichenoid cutaneous reactions to antituberculosis drugs are rare. Herein we report a new case. PATIENTS AND METHODS: A 41-year-old patient was seen for a profuse and pruriginous rash occurring 2 weeks after administration of rifampicin and isoniazid for pulmonary tuberculosis. Dermatological examination revealed polymorphic erythemato-squamous plaques with lichenoid, psoriatic and eczematous features, associated with cheilitis, erosions on the cheeks and diffuse onychodystrophy. The skin biopsy confirmed a lichenoid reaction. The pharmacovigilance investigation incriminated isoniazid and rifampicin. The patient was treated with topical corticosteroids and UVB phototherapy. The outcome involved complete regression of the eruption but with secondary anonychia. DISCUSSION: Antituberculosis drugs including isoniazid and rifampicin are known to induce lichenoid reactions. It is difficult to distinguish the results from lichen planus. The clinical polymorphism of the rash as well as the patient's drug intake militate in favour of a diagnosis of lichenoid reaction. Widespread ungual involvement, which is extremely rare, warranted early management in order to avert irreversible anonychia.

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. LEARNING POINTS: Cutaneous adverse events due to trimebutine maleate, an antispasmodic agent frequently used for the treatment of irritable bowel syndrome (IBS), have rarely been reported.Lichenoid drug eruption (LDE), also called drug-induced lichen planus, is an uncommon cutaneous adverse effect of several drugs.Here we report the first case of trimebutine maleate-induced LDE.
