Flat wart

Skin warts are ubiquitous, self-limiting, benign neoplasms caused by human papillomaviruses (HPV). Several studies have investigated the prevalence and diversity of HPV types in the three main types of skin warts: common, plantar, and flat warts. Using different methodological approaches and diverse populations, several HPV types were detected in skin warts, but often the etiological link remained unconfirmed. This review addresses recently improved multiple strategies for investigating the presence of HPVs in skin warts, covering proper sampling techniques for HPV testing, choice of molecular method(s) for HPV detection, and assignment of the etiological causality of the tested skin wart to a causative HPV type using cellular viral load estimation...

Photodynamic therapy (PDT) uses light energy to excite a photosensitizing agent, leading to production of reactive oxygen species, which exert cytotoxic effects on targeted cells. PDT has emerged as a promising therapeutic modality for the treatment of flat warts caused by human papillomavirus (HPV) infection, by targeting infected keratinocytes and inactivating nonenveloped viral particles. Some patients with recalcitrant flat warts on the face who have poor response to traditional treatment often seek effective therapy to have the warts removed...

Tattoos are a form of decorative body art in which pigment dyes of different colors are inoculated into the skin. It is estimated that 15-25% of general population has one or more tattoos (1), and the reasons for the popularity of this procedure may include greater social acceptance, aesthetic appeal, or perhaps the option of using laser removal techniques to eliminate unwanted tattoos. Even though modern professional tattoos are usually performed in sterile conditions, complications still occur, and with increasing numbers of people getting tattoos, the incidence of tattoo-associated side-effects presenting to dermatologists, which may be as high as 2%, is likely to increase (2)...

BACKGROUND AND AIMS: The treatment of recalcitrant facial flat warts has always been challenging for dermatologists. The pain related to the application of the different treatments, side effects and costs are determining factors in the choice of therapy. To date, it is known that oral isotretinoin administered at a dose of 0.5 mg/kg/day is effective and safe; However, the different adverse effects reported have a dose-dependent behavior and they could limit their use. Our aim is to assess the effect of low-doses of oral isotretinoin to reducing side effects in the complete removal of recalcitrant facial flat warts and the current evidence in this regard...

BACKGROUND: GATA2 deficiency is an inborn error of immunity (IEI) characterized by infectious susceptibility and increased risk of myelodysplasia leading to acute myeloid leukaemia (AML). Oral anomalies already described in this disorder include recurrent viral and fungal infections and oral ulcers. MATERIAL AND METHODS: We report a 9-year-old girl presenting with AML with myelodysplasia-related changes, monosomy 7 karyotype on marrow aspirate, numerous flat warts on her hands and multiple dental caries at oral cavity inspection...

To date, 10 types of human papillomavirus have been identified that cause flat warts, including human papillomavirus type 3, which belongs to species group 2 of the genus alpha papillomavirus. Among these 10 types, human papillomavirus type 94 is most closely related to human papillomavirus type 10, sharing 86% homology. In this study, we conducted polymerase chain reaction analysis with sequencing on samples obtained from cutaneous lesions located on the face and lower legs of an individual, revealing the presence of human papillomavirus type 94...

BACKGROUND AND OBJECTIVES: HPV infections cause a wide spectrum of pathological changes in lower anogenital epithelium. The aim of this study was to investigate the HPV DNA status and histological findings in cervical biopsy specimens diagnosed as flat condyloma. MATERIALS AND METHODS: This study included 20 cervical biopsy specimens diagnosed as flat condyloma. The histopathological criteria and presence of HPV DNA were evaluated. HPV genotyping was determined in HPV-positive specimens using BioEdit software and the results were analyzed in SPSS software...

Unusual viral skin infections might be the first clinical manifestation in children with an inborn error of immunity (IEI). We performed a prospective study from 1 October 2017 to 30 September 2021, at the Department of Pediatric Infectious Diseases and Clinical Immunity of Ibn Rochd University Hospital-Casablanca. During this period, on 591 patients newly diagnosed with a probable IEI, eight of them (1.3%), from six independent families, had isolated or syndromic unusual viral skin infections, which were either profuse, chronic or recurrent infections, and resistant to any treatment...

CASE HISTORY AND CLINICAL FINDINGS: : A 6-year-old Thoroughbred mare developed multiple flat plaques, < 1 cm in diameter, on the left front fetlock. These were treated topically using 5-fluorouracil and resolved after 4 weeks. However, additional similar plaques developed on the left front pastern 5 months later. These lesions resolved within 3 months without treatment. PATHOLOGICAL AND MOLECULAR FINDINGS: One plaque that developed initially and one plaque that developed later were examined histologically...

Bolbostemma paniculatum (Maxim.) Franquet is a unique species in China with a long history of medicinal use, which has the effects of detoxifying, dissolving lumps and dispersing swellings. And it is commonly used to treat many diseases, such as carbuncle and sore, acute mastitis, mammary cancer, scrofula and subcutaneous nodule traditionally. Modern clinical studies have found that B. paniculatum and its compounds can be used for the treatment of a variety of cancers, mastitis, hyperplasia of mammary glands, chronic lymphadenitis, cervical lymph tuberculosis and surgical wart skin diseases, and the curative effect is positive...

AIM: Cutaneous warts caused by human papillomavirus are benign proliferative lesions that occur at any ages in human lives. Updated, comprehensive and systematic evidence-based guidelines to guide clinical practice are urgently needed. METHODS: We collaborated with multidisciplinary experts to formulate this guideline based on evidences of already published literature, focusing on 13 clinical questions elected by a panel of experts. We adopted Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to form classification of recommendations as well as the improved Delphi method to retain respective recommendations with a consensus degree of over 80%...

The SARS-CoV-2 pandemic has affected health systems across the globe, making the use of vaccines more urgent and topical than ever. Since the first months after the introduction of vaccinations, several reactions, both local and systemic, have been reported although they were mostly very mild and only rarely harbingers of more serious complications. We present a case of multiple flat warts onset over the cheeks in a patient after the second dose of mRNA BioNTech-Pfizer BNT162b2 vaccine, and we discuss the possible temporal association between the two events, also considering the patient's antibody status...

(2) Methods: In this paper, we report our twenty-five years' experience with the Erbium laser. More than three thousand patients were treated for common skin disorders such as flat warts, seborrheic keratosis, xanthelasmas, and scars. (3) Results: A complete response was observed in 89...

BACKGROUND: Cutaneous warts are benign epithelial skin lesions, caused by human papilloma virus (HPV). These warts can affect any part of the body, and the clinical presentation of cutaneous warts is highly variable, making it difficult to diagnose. Dermoscopy is a relatively new, non-invasive, diagnostic tool, which can assist in the identification of different types of skin lesions. PURPOSE: The purpose of this research article is to determine the effectiveness of dermoscopy in discerning the most common characteristics of cutaneous warts, in order to provide sufficient information on characteristic features of cutaneous warts, which may aid in differentiating cutaneous warts from other similar skin lesions...

Human papillomavirus (HPV) infections can cause common warts, which usually resolve spontaneously or become recalcitrant, resistant to multiple treatments. In rare cases, they transform into cutaneous giant horns resulting in the tree-man syndrome (TMS). Defective β-HPVs can cause flat warts in epidermodysplasia verruciformis (EV), a genetic disorder. In typical EV, limited to the skin, the mutated genes are critical for keratinocyte-intrinsic immunity, whereas atypical, syndromic EV involves genes controlling T cells...

BACKGROUND: The quadrivalent human papillomavirus (HPV) vaccine was shown to prevent infections and lesions related to HPV6, 11, 16, and 18 in a randomised, placebo-controlled study in men aged 16-26 years. We assessed the incidences of external genital warts related to HPV6 or 11, and external genital lesions and anal dysplasia related to HPV6, 11, 16, or 18, over 10 years of follow-up. METHODS: The 3-year base study was an international, multicentre, double-blind, randomised, placebo-controlled trial done at 71 sites in 18 countries...

Epidermodysplasia verruciformis (EDV) is a rare, autosomal recessive, genetic disorder of immune dysregulation characterized by increased susceptibility to cutaneous human papilloma virus infections. It was first described by Lewandowsky and Lutz in 1922 as a form of epidermal nevus. Its association with skin cancers was proposed by Sullivan and Ellis in 1939. Initial lesions often occur in childhood and are of two types; lifelong eruptions of pityriasis versicolor like lesions and flat wart like papules. The latter is characterized by malignant transformation in 35%-50% of patients especially after 40-50 years of age...

Therapies of common warts are cumbersome and not very effective. Recurrences are common. A new 20 MHz high-intensity focused ultrasound (HIFU) method is introduced as a new potential treatment modality. With HIFU, selected targets in the epidermis and dermis can be treated with full control of the depth and position of the ultrasound lesion and the energy applied to the target. The treatment can be monitored directly in real-time via an integrated dermoscope in the ultrasound probe. Two warts were treated with 8-10 shoulder-by-shoulder treatment doses, focal depth 1...

Dermatologists often encounter keratotic or warty lesions in the genital area. Establishing a clear diagnosis may seem challenging, particularly when the differential diagnosis includes bowenoid papulosis, seborrheic keratosis, and condyloma acuminatum. This study aimed to compare the dermoscopic features of bowenoid papulosis (BP), seborrheic keratosis, and condyloma acuminatum in the genital area. All lesions histopathologically confirmed underwent clinical assessment and dermoscopic observation. Dermoscopically, glomerular vessels were predominant in bowenoid papulosis, whereas seborrheic keratosis was the least vascular-patterned disease...
