RESUMEN

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory skin lesion with an undefined cause. It is more commonly found in the genital area, particularly in adolescents, premenopausal women and postmenopausal women. LSA is difficult to treat and often recurs. The primary treatment for LSA involves the administration of potent topical corticosteroids. Dupilumab is increasingly being used for the treatment of itching in non-atopic dermatitis patients but there are few reports on its use for the treatment of LSA. Here, we present a case of LSA in a 61-year-old woman with extensive vulvar itching. Over four months of dupilumab therapy, significant therapeutic effects were observed, including vulvar skin thinning and pruritus relief without adverse reactions.

RESUMEN

Introduction: Lichen sclerosus is a chronic inflammatory dermatological condition of unknown etiology, primarily impacting the genital epidermis in individuals of all genders, with a higher prevalence observed among postmenopausal women and prepubescent girls. Additionally, extragenital manifestations occur in approximately 20% of the patients diagnosed with genital lichen sclerosus. Notably, folliculocentric extragenital lichen sclerosus is rare and unusual, with only limited instances documented in existing literature. Case Description: We report a 33 years old lady presented with multiple asymptomatic lesions on the dorsal feet for 1 year and similar lesions on the left hand for 4 months. On examination: folliculocentric, shiny, atrophic papules coalescing into reticulated plaques over the dorsum of both feet and few shiny, flat-topped, pink papules over the dorsum of the left hand. A skin biopsy was performed and confirmed the diagnosis of extragenital lichen sclerosus. Conclusion: Acral folliculocentric extragenital lichen sclerosus is an unusual and rare clinical variant. Clinicopathologic correlation is necessary to establish the correct diagnosis. Contribution to the Literature: Herein, we present an unusual presentation of extragenital lichen sclerosus, and we highlight the importance of considering it in the differential diagnosis of guttate acral skin lesions. We also review and summarize relevant cases from the literature in hope to aid physicians, especially dermatologists, to consider and swiftly reach the diagnosis and offer appropriate management. We also hope to bring about new insights and broaden future research efforts regarding lichen sclerosus especially and atrophic skin disease in general.

RESUMEN

Lichen sclerosus (LS) is an uncommon, chronic, inflammatory mucocutaneous disorder found predominantly in females with unknown etiology. It presents as a white sclerotic plaque commonly located on the anogenital area. Extragenital LS is less prevalent, and LS affecting the oral mucosa is extremely rare, with only 39 biopsy-confirmed cases reported in the literature. Due to its several mimicking conditions, histological examination is usually required for a definitive diagnosis, particularly in patients with oral LS. Current evidence-based treatment recommendations for oral LS are unavailable; however, most cases tend to improve after treatment with topical or intralesional corticosteroids. We report a case of a 58-year-old female referred from the otolaryngology department for evaluating an asymptomatic whitish sclerotic plaque on the lower lip mucosa that had existed for 1 year. Following a punch biopsy, the patient was diagnosed with LS of labial mucosa. The condition improved after 2 months of treatment with topical and intralesional corticosteroids. The present case report raises awareness in recognizing oral LS and contributes to knowledge of this rare disorder.

RESUMEN

PURPOSE: We evaluate the efficacy and safety profiles of currently available conservative management options for penile and urethral lichen sclerosus. MATERIALS AND METHODS: A systematic review of existing literature on lichen sclerosus was conducted utilizing the PubMed, Embase, and Web of Science databases. References were assessed for relevance to nonsurgical management of male genital lichen sclerosus by title and abstract by 3 independent reviewers, then reviewed in full and in duplicate by 5 independent reviewers. RESULTS: Seventeen studies describing conservative management of histologically confirmed penile and urethral lichen sclerosus in male patients were included in the final review. We present available evidence supporting the use of 4 major treatment modalities represented in the existing literature: topical corticosteroids, tacrolimus, platelet-rich plasma, and CO2 laser. We also briefly discuss the limited studies on the use of oral acitretin and polydeoxyribonucleotide injections. Outcomes assessed include symptoms, clinical appearance, quality of life, sexual satisfaction, adverse effects, and long-term efficacy of treatment. CONCLUSIONS: Topical corticosteroids remain the mainstay of conservative management of penile and urethral lichen sclerosus, with current literature supporting the use of other therapies such as tacrolimus and platelet-rich plasma as alternatives or adjuvant treatments when escalation of treatment is necessary. Future research should further explore the efficacy and safety of newer therapies through additional controlled clinical trials in the targeted population.

RESUMEN

SIGNIFICANCE: ALA-PDT effectively treats Vulvar lichen sclerosus et atrophicus (VLSA), but it requires multiple repetitions for satisfactory results. To enhance efficacy, we employed a combination of high-frequency electrocautery therapy and ALA-PDT in treating seven VLSA patients. APPROACH: Lesions and leukoplakia in the seven women with VLSA were removed using a high-frequency generator. PDT was administered after wound healing, and it was repeated six times. Follow-up assessments were carried out at 1, 3, and 6 months to evaluate the severity of pruritus and investigate lesion repigmentation. RESULTS: Following the combined therapy, the disappearance of pruritus was observed in all patients, and normal color and thickness were restored to their skin. Two patients reported mild pruritus with a score of 2 one month after treatment, which persisted until the 6-month follow-up, while the remaining patients remained free from pruritus. No recurrence of skin lesions was observed in any of the patients. CONCLUSIONS: The combined therapy for the treatment of VLSA is found to be convenient, effective, and easily promotable.

RESUMEN

Lichen sclerosus et atrophicus (LSA) is an inflammatory dermatosis of unknown etiology, usually affecting the genital region, with extragenital involvement being uncommon. The coexistence of LSA and morphea in the same lesion is rare. The present study aims to demonstrate that LSA and morphea might share similar pathologic processes. We present a case of a 53-year-old female patient with extragenital lesions with clinical appearance and histopathological features of both LSA and morphea. Finally, the two diseases might lie on the same disease spectrum.

RESUMEN

Background Postmenopausal women comprise a very unique population with various dermatological, genital, and oral dermatoses due to the various physiological, age-related, and hormonal changes in this period, which have not yet been studied extensively, especially in India. Aims and objectives The aim of the study was to study the various epidemiological and clinical patterns of postmenopausal dermatosis. Material and methods We conducted a single-center observational cross-sectional study on 223 postmenopausal women attending the dermatology outpatient department (OPD) with various dermatological concerns to understand the various clinical patterns and presentations of postmenopausal dermatoses. Women were interviewed face to face using a pre-designed, pre-tested questionnaire. A detailed history followed by general physical, systemic, and cutaneous examination was done, along with investigations wherever needed. Results A total of 223 postmenopausal women were enrolled in our study, with a mean age group of 58.4 ± 5.1 years. The mean age of menopause in our study was 48.7 ± 3.8 years. In our study, 186 (83.4%) women had cutaneous dermatosis, 65 (29.1%) had genital dermatosis, 23 (10.3%) had oral mucosa involvement, 75 (33.6%) had hair disorders, and 58 (26%) had nail disorders. Limitation The limitation of our study is that it is a single-center study, and women with active HIV or hepatitis infection or known malignancy were excluded from the study. Conclusion A broader understanding of the diverse dermatological concerns of postmenopausal women would enable dermatologists to be better equipped to identify and treat postmenopausal dermatosis as well as provide better support to women going through this phase of life.

RESUMEN

The urological examination includes the inspection of the external male genitals. Harmless normal variants, such as heterotopic sebaceous glands and pearly penile papules must be differentiated from malignant and infectious manifestations. Lichen sclerosus et atrophicus is a frequent connective tissue disease that can lead to functional impairments and an associated high level of suffering for those affected. Both conservative and invasive treatment options are available. Sexually transmitted diseases, such as syphilis, are gaining increasing importance in routine clinical and daily practice due to the increasing incidence in recent years. An early diagnosis and treatment of malignant neoplasms, such as Queyrat's erythroplasia can be carried out by routine inspection of the genital skin.

RESUMEN

Background Lichen sclerosus et atrophicus (LSEA) is a chronic inflammatory dermatosis of genital and extragenital sites with a prevalence ranging from 9% in prepubertal patients to 50% in postmenopausal patients. Chat generative pre-trained transformer (ChatGPT) is an artificial intelligence tool designed to assist humans based on supervised and reinforcement techniques. In this study, we aimed to evaluate the characteristics of patients with LSEA using ChatGPT. Methods In this retrospective study, we included all patients who presented to the outpatient dermatology department during 2017-2022 at a tertiary care teaching hospital in South India. Information regarding demographic data, characteristics of LSEA, comorbidities, and associated autoimmune disorders was gathered using a medical chart review. Following data analysis and drafting of the manuscript, the utility of ChatGPT-3 and ChatGPT-4 in finalizing the draft was assessed. Results Of 20 patients diagnosed with LSEA, 16 (80%) and four (20%) patients were females and males, respectively. Of them, 50% of female patients had attained menopause. While 65% of patients had genital LSEA, 30% of patients had extragenital LSEA only, and 5% of patients had both genital and extragenital LSEA. Furthermore, four (20%) patients were prepubertal children. Of four male patients, two (50%) were younger than 18 years of age, and one patient was diagnosed with balanitis xerotica obliterans. The commonest associated features in LSEA included joint involvement (30%), hypertension (25%), and anemia (15%). Rare concomitant disorders included psoriasis, asthma, and basal cell carcinoma over the nose. Conclusions LSEA may be confused with other various dermatoses, such as morphea, vitiligo, and lichen planus. A high index of suspicion is required, especially in children, to diagnose it early and intervene to prevent further complications. Its relationship with autoimmune disorders and comorbidities warrants further large-scale studies. ChatGPT was unreliable in the literature search due to the provision of non-existent citations. ChatGPT-4 was better than ChatGPT-3 since it provided few true publications. ChatGPT was used in this study to summarize the articles identified by the authors during the literature search and to correct grammatical errors in the final draft of the manuscript.

RESUMEN

In this case report, we outline a case of a 36-year-old woman who presented to the dermatology clinic with a history of a hypopigmented macule on her lip. After conducting hepatitis C antibody testing and a shave biopsy, the patient was diagnosed with lichen sclerosus. Because of the increased risk for squamous cell carcinoma, she underwent an anogenital exam, where no lesions were found.

RESUMEN

Tumor necrosis factor-alpha inhibitor therapy for inflammatory bowel disease may be associated with paradoxical cutaneous adverse events, most commonly psoriasiform eruptions. We present the case of a pediatric female patient with Crohn's disease who developed multiple concurrent cutaneous eruptions while on infliximab treatment, including morphea, psoriasiform dermatitis, and genital lichen sclerosus. Although refractory to skin-directed treatments, all three conditions resolved upon discontinuation of infliximab, supporting their development as a paradoxical reaction to infliximab therapy.

RESUMEN

Introduction: Lichen sclerosus (LS), is an uncommon inflammatory dermatosis with preferential involvement of anogenital region. Diagnosis of LS is mainly clinical, but clinical differentiation from conditions like vitiligo, morphea may be a difficult task at times that often requires histological analysis. Dermoscopy is one such non-invasive tool which can help diagnose the disease. There is paucity of Indian data on dermoscopy of LS. Objectives: To evaluate clinical, dermatoscopic patterns of LS and correlate them with histopathology. Methods: The study was conducted in a tertiary hospital after obtaining consent from 20 patients. OITEZ e-scope digital microscope was used to evaluate the lesions. Both polarized and nonpolarized mode were used and skin biopsy was done to confirm diagnosis. Results: Based on morphology, LS was classified as scleroatrophic lesions (61.5%), guttate lesions (30.8%) and hyperkeratotic lesions (7.7%). Dermoscopic analysis revealed structureless white to yellow areas as most common finding (100%) followed by chrysalis like structure (80.8%). Linear irregular vessels were seen in 61.5% lesions and perifollicular scaling in 50.0% lesions. Keratotic plugs were seen in 50.0% lesions. A new characteristic finding, "rosettes" was seen in 38.5% lesions has never been reported with LS before. Non polarized mode was particularly useful for identifying texture changes, keratotic plugs and minute scales which were not visible otherwise. Conclusions: Dermoscopy is a simple diagnostic tool that helps in the early diagnosis of LS with specific pattern which can avoid invasive procedure like biopsy. Both non-polarised and polarized dermoscopy must be done to visualize the changes of LS well.

RESUMEN

Lichen sclerosus (LS) is a chronic inflammatory mucocutaneous disease of unknown aetiology. About 85% of total cases of LS are genital cases, while extragenital form is seen in only 15-20% of cases. Extragenital LS (EGLS) can occur simultaneously with genital form; however, in 6% of the cases, only extragenital form has been described. Genetic, autoimmune, infectious, environmental and hormonal factors are implicated in its aetiology. Extragenital LS presents as asymptomatic white opalescent papules, which cluster in plaques and slowly progress over time resulting in parchment-like skin usually involving upper trunk, neck and shoulders. Lesions are frequently accompanied by purpura/haemorrhagic spots. The relationship with morphoea has been a topic of debate. Association with several autoimmune diseases has been observed. Diagnosis is usually based on clinical and dermoscopic examination and further supported by histopathological findings. LS needs to be differentiated from several other dermatological conditions such as discoid lupus erythematosus, vitiligo, mycosis fungoides (hypopigmented variant), lichen planus, graft-versus-host disease and morphoea depending upon the stage of the disease. Generally, extragenital LS is believed to lack carcinogenic potential. However, case reports with possible malignant transformation have been described. In this article, the authors have described a concise review of the extragenital form of LS.

RESUMEN

Vulval Lichen Sclerosus (VLS) is a chronic inflammatory dermatosis that significantly impacts the quality of life. We report 2 cases of severe treatment-resistant VLS treated with subcutaneous adalimumab. One patient showed modest clinical improvement with no significant improvement in quality-of-life measures. The second patient showed a significant improvement in both clinical and quality-of-life measures. Both patients achieved optimal control with a maintenance dosing of 40 mg subcutaneously weekly. Adalimumab may be a treatment option for recalcitrant VLS; however, clinical trials are required to confirm efficacy for this indication.

RESUMEN

Lichenoid reactions are one of the most frequently observed toxicities with anticancer agents and, recently, a rapid emergence of immunotherapies in oncology has hastened the need to better characterize their unique toxicity profiles, particularly for less common skin toxicities, including anogenital lichen sclerosus et atrophicus (LSA). This case series describes four patients with advanced cancer (one melanoma, two lung cancers, and one kidney tumor) developing LSA lesions while receiving an immunotherapy. Medical records from 2017 to 2020 were retrospectively reviewed. Two patients received pembrolizumab, anti-programmed cell death-1 (PD-1), one nivolumab, anti-programmed cell death-1 (PD-1), and one ipilimumab, an immune checkpoint inhibitor. LSA emerged after a median of 3 months (range, 2-4 months) from starting immunotherapy. All LSA cases were grade 2. Three cases occurred on the penis and one case on the anus. All patients improved after a specific treatment for LSA, and no LSA-related antineoplastic treatment interruption/life-threatening condition were reported. To date, this is the first case series of LSA lesions associated with immunotherapy. Early LSA recognition and management is helpful in cancer patients on immunotherapy allowing a long survival and treatment response.
