Does Molluscum Contagiosum Need to be Managed Differently in Atopic Children?

The association between molluscum contagiosum and concomitant atopic dermatitis and its impact on clinical features and treatment outcomes remains unclear. This retrospective study, conducted in the paediatric dermatology clinic of a tertiary medical centre, aimed to compare molluscum patients with and without atopic dermatitis. A total of 615 children with molluscum were included, 13.17% of whom had atopic dermatitis. While the latter group exhibited higher lesion count and itchiness (p=0.026 and p=0.044, respectively), no significant differences were observed in average lesion diameter, ulceration, purulence, and erythema (p=0.239, p=0.730, p=0.682, and p=0.296, respectively). Both groups showed comparable responses to molluscum-specific and supportive treatments, with no distinct difference in outcomes or recurrence of visits. It was concluded that atopic dermatitis does not exacerbate molluscum morbidity, inflammation markers, treatment outcomes or recurrence rates.

Molluscum contagiosum presenting as periorbital abscess in immunocompetent children.

Molluscum contagiosum presenting as a periorbital region abscess is unusual. The virus generally causes a self-limiting localized disease in children. Presentation as an abscess has been reported mainly in immunocompromised patients. We performed a retrospective study of ten children treated for Molluscum contagiosum infection presenting as periorbital abscess. Data investigated included age, immunocompetence, systemic antibiotic treatment, clinical findings, and histopathology. All children were immunocompetent. Bacterial cultures taken in six of the ten children were positive in two. Seven patients received oral antibiotics before presentation but required IV antibiotics on admission. One patient received IV antibiotics only. All antibiotic treatment had very limited effect. Two patients had no antibiotic treatment. CT imaging in one case where orbital cellulitis was suspected showed no significant intraorbital findings with anterior involvement only. Nine out of ten children had surgery and intra-operative cryotherapy at our center with immediate improvement and recovery. One child whose parents initially refused surgical excision had initial limited clinical improvement of periorbital swelling with antibiotics. However, the lesions were excised shortly following discharge from our hospital at another medical center with a complete cure. Molluscum is a cause of periorbital abscess in immunocompetent children which should be part of the differential diagnosis in periorbital/adnexal infection. Antibiotic treatment has a limited effect, and the abscess is most likely a virally triggered reaction. Surgical excision and intra-operative cryotherapy are curative of the disease in our experience.

Quality of life in children with skin disease: A Spanish sample.

INTRODUCTION: The impact of skin diseases on quality of life varies widely, and some can have an impact similar to that of asthma or cystic fibrosis. MATERIAL AND METHODS: We conducted a cross-sectional, observational and descriptive study with the aim of describing the degree to which quality of life was affected in paediatric patients managed in a dermatology clinic by means of the Children's Dermatology Life Quality Index (CDLQI). RESULTS: In our study, the skin disease with the greatest impact on quality of life was atopic dermatitis, chiefly on account of symptoms like pruritus and insomnia. It was followed by acne, mainly due to the associated negative feelings (shame, sadness, etc.). Quality of life in patients with viral warts and molluscum contagiosum was mostly affected by the treatment, chiefly based on cryotherapy. Most patients with nevi or café-au-lait spots did not have a decreased quality of life, although up to one third of them had negative feelings in relation to their skin disease. DISCUSSION: Atopic dermatitis was the common skin disease that caused the greatest impairment in quality of life in our sample, although other diseases also had an impact on different dimensions of quality of life. We ought to underscore the recommendation to use less painful treatments than cryotherapy for viral warts and molluscum contagiosum, as the impairment in quality of life in paediatric patients with these conditions was mainly due to the treatment.

Heterologous effect of influenza vaccination on molluscum contagiosum infection; a case report of siblings.

BACKGROUND: Molluscum contagiosum virus (MCV) is a benign, common cutaneous infection predominantly affecting the younger pediatric population. Traditional treatments may be time consuming with variable efficacy. Time to spontaneous resolution is variable and treatment is often sought to shorten duration of infection, prevent further autoinoculation, prevent infectious spread to others and treat cosmetic intolerability. CASE PRESENTATION: We present the case of two patients with complete, simultaneous clearance of their molluscum contagiosum infections after receiving a routine 2018 quadrivalent influenza vaccination. Neither patient has had recurrence of molluscum contagiosum or permanent scarring. We review trials of intralesional immunotherapy in treatment of cutaneous infections to theorize the mechanism of MCV infection clearance post influenza vaccination. CONCLUSION: We propose a delayed-type hypersensitivity reaction was induced as a heterologous effect of the influenza vaccination, similar to that seen in current immunotherapy treatments. This is the first reported case of MCV-directed immune reaction with infection clearance after influenza vaccination.

Eyelid molluscum contagiosum lesion in a pediatric patient treated with topical nail polish.

Molluscum contagiosum causes umbilicated periocular lesions, which commonly affect children. Topical clear nail polish for treatment of molluscum has been reported anecdotally, but there are few reports in the medical literature. We report the case of an eyelid molluscum lesion in an 8-year-old girl that resolved with 4 topical applications of nail polish over 6 weeks.

British Association for Sexual Health and HIV national guideline for the management of Genital Molluscum in adults (2021).

This guideline offers recommendations on diagnosis, treatment regimens and health promotion principles needed for the effective management of genital molluscum, including management of the initial presentation and recurrences. The Primary focus of the guideline is on infection which affects the genital area and has a sexual mode of transmission. This is an update to the guideline previously published in this journal in 2014.

Molluscum and Tinea and Warts, Oh My!

The skin is the largest organ in the human body, and it acts as the barrier between the world and our bodies. As such, it is constantly being exposed to infections, irritants, and allergens. Approximately one-third of primary care visits involve at least one skin complaint. This may manifest as a rash, a lesion, pruritis, pigment changes, or textural abnormalities. Whatever the presentation, it is important to know the common causes of these skin abnormalities and the appropriate management. Just as important as management is the ability to set expectations for patients, as many common skin conditions can be difficult to treat and may take significant time to resolve. This article will highlight some of the most common skin lesions we see in pediatric patients. [Pediatr Ann. 2022;51(1):e2-e5.].

Intralesional measles, mumps, and rubella vaccine immunotherapy in molluscum contagiosum: A retrospective observational study from a tertiary care center in north India.

Molluscum contagiosum (MC) is a mucocutaneous viral infection, often self-limiting but untreated lesions can often last for 2 months to 2 years. Previously intralesional measles, mumps, and rubella (MMR) vaccine has been tried for the treatment of warts but no studies exist of its use in MC. We report our experience with intralesional MMR in 22 patients of MC. The study was carried out to assess the efficacy and safety of intralesional MMR vaccine in patients of MC. We retrospectively analyzed records of patients who received intralesional MMR for MC from September 2018 to September 2019. Demographic characteristics, number, size, and site of molluscum lesions, number of MMR injections given, and response were recorded. Records of 22 patients were analyzed. There were 10 males and 12 females. The age of the patients ranged from 6 to 50 years with a mean of 19.72 ± 10.92. At the end of 12 weeks, 18 patients (81.8%) had complete clearance of lesions, with 4 patients (18.18%) having a partial response of more than 50%. No patient showed less than 50% or no response. In only one patient who had giant molluscum, postinflammatory hyperpigmentation was noted. No other adverse effect was seen in any of the patients. MMR is a safe, effective, easy to administer, time-saving, and inexpensive therapy for lesions of MC.

2020 European guideline on the management of genital molluscum contagiosum.

Molluscum contagiosum is a benign viral epidermal infection associated with high risk of transmission. The guideline is focused on the sexually transmitted molluscum contagiosum. The diagnosis is clinical with characteristic individual lesions, termed 'mollusca', seen as dome-shaped, smooth-surfaced, pearly, firm, skin-coloured, pink, yellow or white papules, 2 - 5 mm in diameter with central umbilication. Dermoscopy may facilitate diagnosis. Therapeutic options are numerous, including physical treatments (cautery, curettage and cryotherapy), topical chemical treatments (e.g. podophyllotoxin and imiquimod) or waiting for spontaneous resolution in immunocompetent patients. In pregnancy, it is safe to use physical procedures (e.g. cryotherapy). Immunosuppressed patients develop severe and recalcitrant molluscum lesions that may require treatment with cidofovir, imiquimod or interferon. Patients with molluscum contagiosum infection should be offered to be screened for other sexually transmitted infections.

A comparative study of topical cantharidin and intralesional PPD to treat molluscum contagiosum.

Background: The immune system plays an important part in the clearance of molluscum contagiosum (MC) and, therefore, there has lately been a trend in using immunotherapy in MC therapy. Tuberculin-purified protein derivatives (PPDs) and topical cantharidin have not earlier been compared with their effectiveness in therapyAim: The aim of this research was to determine the effectiveness and security of intralesional immunotherapy in the therapy of MC with tuberculin PPD versus topical cantharidinPatients and methods: Twenty patients with various MC lesions received topical cantharidin as control (group A) and 20 MC patients received intralesional tuberculin PPD following prior intradermal immunity tests (group B ).Results: Complete clearance of lesions was detected in 90.0% of patients in the cantharidin group; the partial response was detected in10.0% of the patients. However, in the PPD group, 85% of the patients showed a complete response and 15% showed a partial response, with no significant difference in the clinical response between the two groups. Mild side effects were detected .Conclusion: The results suggest that intralesional PPD and topical cantharidin 0.7% are effective and safe treatment modalities, but benefits of intralesional PPD is being a simple, effective and safe treatment with tolerable pain and can be an alternative treatment for multiple resistant types .

Intralesional vitamin D immunotherapy for recalcitrant molluscum contagiosum.

Molluscum contagiosum (MC) is a benign viral infection, which may have florid manifestations in immunosuppressed patients. Moreover, the treatment is often unsatisfactory in these patients and it maybe recalcitrant. We hereby report the use of intralesional vitamin D immunotherapy in two immunosuppressed patients with persistent widespread MC lesions.
