Benign cephalic histiocytosis in a 2-year-old boy with an inconspicuous clinical presentation at onset.

We report on a 2-year-old boy whose initially inconspicuous skin lesions later on evolved into a typical clinical presentation of benign cephalic histiocytosis (BCH). The diagnosis of BCH can often be made on clinical grounds without the need for an extensive diagnostic work-up. Given the benign and self-limited course of the disease treatment is not required and the clinical management can be limited to a watchful waiting approach.

Rosacea in children: a review.

Rosacea is a facial inflammatory disorder that shows an increasing incidence with age. While rosacea is common > 60 years of age, pediatric rosacea is uncommon. Diagnostic criteria are based on clinical symptoms. Laboratory investigations and histopathology are only needed to exclude other differential diagnoses. There are several subtypes such as erythemato-telangiectatic, papulo-pustular, periorificial, and granulomatous variants. In contrast to adult rosacea, phymatous subtypes do not belong to pediatric rosacea. A special subtype seen in infants and children is an idiopathic facial aseptic granuloma. Genetic and environmental factors contribute to its pathogenesis. Treatment options are in analogy to adult rosacea classified into topical and systemic drugs. In the case of oral tetracyclines, discoloration of teeth and impairment of enamel are possible adverse events. CONCLUSION: Pediatric rosacea belongs to the rosacea spectrum but has peculiarities compared to the adult subtype. WHAT IS KNOWN: • Rosacea is a chronic inflammatory disorder different from acne. • Rosacea gets more common with advanced age. WHAT IS NEW: • Pediatric rosacea is an uncommon subtype with peculiar clinical presentation. • Demodicosis is very rare in immunocompetent children.

Analysis of willingness-to-pay for the treatment of acute facial inflammatory dermatoses with red and yellow light from light-emitting diodes / 中华皮肤科杂志

Objective:To analyze the willingness-to-pay (WTP) for the treatment of acute facial inflammatory dermatoses with red and yellow light from light-emitting diodes (LEDs), and to evaluate their cost-effectiveness.Methods:A questionnaire survey was conducted on outpatients with or without acute facial inflammatory dermatoses, which mainly manifested as erythema and swelling, in Department of Dermatology, Xiangya Hospital from August 2019 to June 2020. The WTP for the treatment of acute facial inflammatory dermatoses of varying severity with red and yellow light from LEDs were investigated, clinical data on the prevalence of facial skin diseases, previous medical visits and quality of life were collected, and a benefit-cost analysis was conducted. Logistic regression analysis was conducted to investigate factors influencing the patients′ WTP for the LED treatment.Results:The median WTP of the subjects was 200, 300 and 300 RMB yuan for 1-session treatment of three cases of acute facial inflammatory dermatoses of increasing severity assumed to require 1-, 3-, and 5-session LED treatments respectively, and the WTP for 1-session treatment of case 2 and case 3 was higher than the cost of 1-session LED treatment (217 RMB yuan). The subjects with high family incomes (≥ 100 000 RMB yuan/year) were significantly more willing to pay for the treatment than those with low family incomes (< 100 000 RMB yuan/year) (case 1: 40.46% vs. 27.50%, χ2 = 7.00, P = 0.008; case 2: 60.69% vs. 44.5%, χ2 = 9.75, P = 0.002; case 3: 51.20% vs. 48.8%, χ2 = 6.54, P = 0.011), and the subjects who never suffered from facial inflammatory dermatoses were significantly more willing to pay for the treatment than those who ever suffered (case 1: 35.49% vs. 28.82%, χ2 = 1.56, P = 0.212; case 2: 56.10% vs. 42.34%, χ2 = 5.92, P = 0.015; case 3: 68.32% vs. 56.75%, χ2 = 4.58, P = 0.032). No significant difference in the WTP was observed among patients with different facial dermatoses, different degrees of impairment on quality of life, or different treatment experience (all P>0.05) . Conclusion:The cost of red and yellow light from LEDs for the treatment of acute facial inflammatory dermatoses manifesting as erythema and swelling was highly acceptable in this population, and it was worthy of clinical promotion.

Facial Dermatoses in Patients With Blepharitis: a Cross-sectional Prospective Analysis.

Introduction: The relationship between facial dermatoses and blepharitis has been known for a long time. Objectives: We aimed to investigate the frequency of accompanying facial dermatoses in patients with blepharitis and their relationship with the severity of blepharitis. Methods: In this cross-sectional study, 95 patients with blepharitis were examined for attending facial dermatoses. The type of blepharitis, the severity of blepharitis, and the degree of dry eye were determined in the patients. Dermoscopic and microscopic examinations were used in the diagnosis of facial dermatoses. The history of allergic rhinitis was questioned because Demodex species frequently accompany blepharitis, facial dermatoses, and allergic rhinitis patients. Mann-Whitney U test was used compare 2 independent groups. In comparing categorical variables, Pearson chi-Squared, Fishere Exact, and Fisher-Freeman-Holton tests were used. Results: At least 1 facial dermatosis was detected in 84.2% patients, and we did not see any facial dermatosis in 15.8% ones. No patients had acne, which is one of the most common facial dermatoses. The most common facial dermatosis detected in our patients was facial demodicosis (57.9%). It was followed by seborrheic dermatitis (22.1%) and rosacea (12.6%), respectively. In addition, 2.1% of the patients had atopic eyelid dermatitis, 23.2% had a history of allergic rhinitis, and 63.2% had ocular demodicosis. Conclusions: It is essential to perform dermatological examinations of all patients with blepharitis in terms of accompanying facial dermatoses and their early diagnosis.

Facial dermatoses and use of protective mask during Covid-19 pandemic: A clinical and psychological evaluation in patients affected by moderate-severe atopic dermatitis under treatment with dupilumab.

During the SARS-COV-2 pandemic, using face masks became mandatory in many countries. Although evidence suggests that masks can exacerbate several inflammatory skin diseases, few studies focus on their real impact on eczema localized to the face in atopic dermatitis (AD) patients. The aim of this study is to evaluate facial eczema prevalence during pandemic and its psychological impact in AD patients pre-assessed for systemic treatment and/or in therapy with dupilumab. This study includes 71 patients affected by moderate-severe AD, treated with dupilumab at SCDU of Dermatology in Novara, Italy. We calculated the number of subjects with facial involvement in pre- and post-pandemic periods and the related localization trend. We evaluated, in the two groups, clinical and psychological indicators recorded at each visit and the score modifications during the observational period. No statistically significant differences were observed in facial eczema prevalence, between pre- and post-pandemic periods (p = 0.7618) and in facial eczema remission among the two groups (p = 0.1903). In post-pandemic period, psychological scores were significantly lower (DLQI and HADS respectively with p < 0.0001 and p = 0.0025) and the reduction in EASI score during observational period was significantly greater (p = 0.0001). Our analysis revealed a potential protective effect of masks on face eczema, suggesting that they could enhance dupilumab efficacy. Face masks, covering sensitive areas, can positively contribute to mental distress in patients with facial eczema, and being associated with a lower allergic diseases incidence may sustain dupilumab in reducing AD severity.

The change in the frequency and severity of facial dermatoses and complaints in healthcare workers during the COVID-19.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to a dramatic increase in the use of personal protective equipment (PPE). However, the increased use of PPEs may lead to facial skin complaints. AIMS: This survey study aims to evaluate the effect of the COVID-19 pandemic on facial dermatoses and complaints. METHODS: A total of 1017 volunteers (age 18-60 years), consisting of healthcare workers, participated in the study. In the present study, healthcare professionals were screened for facial dermatoses and complaints between 1 and 15 April 2021 with an online survey. RESULTS: The vast majority of the survey were women (82.4%) and between 26 and 35 years old (49.2%). The most new-onset facial complaints were acne (25.3%) and lip dryness (29.2%). Along with the pandemic, 50.9% of patients with seborrheic dermatitis had an increase in lesions. Another remarkable result was a 60.5% increase in acne complaints. Moreover, the rate of exacerbations of rosacea, melasma, and lip dryness was increased after the COVID-19 pandemic (39.1%, 22.0%, and 42.7%, respectively). Exacerbations of seborrheic dermatitis, acne, and lip dryness have occurred more frequently in females when compared to males (p < 0.001). CONCLUSIONS: The current pandemic has had serious impacts on facial dermatoses which had to be managed carefully. Compared to the pre-pandemic period, there was a significant increase in the frequency and severity of complaints in facial dermatoses related to PPE. If the complaints that may develop due to PPE are known in advance, their development can be prevented by taking precautions against them.

Clinical implications of facial psoriasis in children and adolescents.

BACKGROUND/OBJECTIVES: The clinical implications of facial involvement in pediatric patients with psoriasis have not been adequately studied. The objectives of this study are to evaluate the association between facial involvement and clinical features including disease severity of psoriasis in children and adolescents. METHODS: The clinical features of patients aged below 20 years diagnosed with psoriasis were retrospectively evaluated and grouped based on the presence or absence of facial involvement at presentation. Demographic and clinical data were compared between groups. RESULTS: Of the 175 patients, 110 patients (62.9%) had facial involvement of psoriasis at presentation. The group with facial involvement was significantly younger at disease onset (p = .032) and had a higher body mass index (BMI) (p = .043) and psoriasis area and severity index (PASI) score (p <.001). The severity of pruritus was significantly higher in the facial than in the non-facial group (p = .020). Involvement of the nose was associated with the highest disease severity as assessed by the PASI score and affected body surface area. A significantly higher number of treatment modalities were used in the facial group than in the non-facial group (p = .013). The BMI (odds ratio (OR), 1.39; 95% CI (confidence interval), 1.07-1.80) and PASI score (OR, 1.45; 95% CI, 1.03-2.03) were independent factors associated with facial involvement of psoriasis. CONCLUSIONS: Facial involvement in psoriasis was associated with higher disease severity and more treatment modalities in children and adolescents.

Occupational facial dermatoses related to mask use in healthcare professionals.

BACKGROUND: Mask use can lead to facial dermatoses due to factors, such as hyperhydration, seborrhea, high humidity caused by sweating, and the occlusive effect of the mask. AIM: We investigated mask-related facial dermatoses in healthcare personnel who, since the beginning of the COVID-19 pandemic, had to wear a mask for long hours. METHODS: In this study, healthcare professionals working at Medipol Mega University Hospital since the beginning of the pandemic were screened for facial dermatoses between December 2020 and February 2021 with a dermatological examination and interview. RESULTS: Of the 101 healthcare professionals, 51 (50.5%) were doctors and 50 (49.5%) nurses, and 36 (35.6%) were male and 65 (64.4%) were female. All the participants had been actively working at the hospital for 35-46 weeks since the beginning of the pandemic and wearing N95 or surgical masks for an average of 6-13 h a day. During the dermatological examination, the most common facial dermatosis was acne, which was observed in 55.4% (n = 56) of the cases. Of the 56 acne cases, 41.1% (n = 23) had acne in their history, while 58.9% (n = 33) had new-onset acne. Being female, using a N95 surgical mask compared to surgical mask, and the daily average duration of mask use were determined as risk factors for acne development due to mask use. CONCLUSIONS: The use of masks, more frequently N95, caused both an increase in existing acne and the development of new acne.

Skin Exposures, Hand Eczema and Facial Skin Disease in Healthcare Workers During the COVID-19 Pandemic: A Cross-sectional Study.

The COVID-19 pandemic has led to enhanced hygiene procedures and use of personal protective equipment, but also to increased attention to occupational skin disease in healthcare workers. The occurrence of hand and facial skin disease in > 5,000 Swedish healthcare workers was investigated in a questionnaire survey. Levels of skin exposure related to hygiene procedures and personal protective equipment were recorded. Caring for patients with COVID-19 entailed higher levels of wet work and face mask exposures, and was associated with higher 1-year prevalence of both hand eczema (36%) and facial skin disease (32%) compared with not being directly engaged in COVID-19 care (28% and 22%, respectively). Acne and eczema were the most common facial skin diseases; for both, a dose-dependent association with face mask use was found. Dose-dependent associations could be shown between hand eczema and exposure to soap and gloves, but not to alcohol-based hand disinfectants.

Mask-induced Koebner phenomenon and its clinical phenotypes: A multicenter, real-life study focusing on 873 dermatological consultations during COVID-19 pandemics.

During COVID-19 pandemic, wearing masks for prevention became mandatory but evidence suggest that is also detrimental for skin. Although facial dermatoses due to masks increase in both healthcare workers and general population, a pathogenetic hypothesis remains still elusive. We aimed to evaluate the prevalence of dermatological consultations due to Koebner triggered dermatoses In this prospective, multicenter, real life study carried out in Italy from March 11th to December 11th 2020 during COVID-19 pandemics, dermatological consultations (in-person and telemedicine) to study the prevalence of Koebner (KB) phenomenon due to masks were evaluated. Boyd and Nelder classification was adopted for Koebner phenomenon and Bizzozero's for KB intensity. A total of 229/873 (26.2%) dermatological consultations were KB triggered dermatoses and lesions were located in mask-covered ear area (76 [33.2%]), malar area (73 [31.8%]), perioral area (53 [23.1%]), and nose (27 [11.8%]). The first KB category grouped 142 patients (psoriasis, vitiligo, maskne, and mask rosacea), the second one 24 (warts, molluscum contagiosum, and impetigo), the third one 46 (atopic dermatitis), and the fourth one 17 (eczema). Among previously KB negative psoriatic patients that became KB positive, 9/13 (69.2%) had discontinued or modified the prescribed antipsoriatic treatment. Mask-related Koebner phenomenon is an important clinical sign to orient clinician's therapeutic protocols during COVID-19 pandemic, especially in patients with psoriasis.

Risk factors of postinflammatory hyperpigmentation after laser in treatment of acquired bilateral nevus of Ota-like macules / 中华医学美学美容杂志

Objective:To analyze the risk factors of postinflammatory hyperpigmentation (PIH) after laser in the treatment of acquired bilateral nevus of Ota-like macules (ABNOM).Methods:A retrospective study was conducted to follow up 120 patients with acquired bilateral nevus of Ota-like macules in the Department of Laser and Physiotherapy, Guangzhou Institute of Dermatology between January 2011 and December 2018, which accepted 1064-nm Q-switched neodymium: yttrium-aluminum-garnet laser treatment. The difference was analyzed between different age, sex, clinical classification, Fitzpatrick skin classification, ABNOM with melasma and postinflammatory pigmentation after laser treatment. Logistic regression was used to analyze the risk factors of postinflammatory hyperpigmentation after 1064-nm Q-switched neodymium: yttrium-aluminum-garnet laser treatment of acquired bilateral nevus of Ota-like macules.Results:Fifty-three ABNOM patients (44.17%) developed PIH after laser treatment. Univariate analysis showed that age, clinical classification, Fitzpatrick skin classification and the patients with both ABNOM and melasma all affected the occurrence of PIH after laser in the treatment of ABNOM, and the difference was statistically significant ( P<0.01). Logistic regression showed that older age, more severe clinical classification and the presence of ABNOM with melasma were the risk factors of PIH after treatment of ABNOM. Conclusions:ABNOM patients should be treated as early as possible. The risk of inducing PIH is great after laser treatment in patients with more severe clinical classification and patients with both ABNOM and melasma.

"Doll #135 with vitiligo": Are alopecia and vitiligo Barbie worth the hype?

Toy manufacturer Mattel released a new line of diverse Barbie dolls earlier this year, including dolls with alopecia and vitiligo. The new dolls have been widely celebrated, with both media and dermatologists proposing that the dolls could provide significant benefits for the low self-esteem and societal exclusion suffered by children with similar dermatoses. However, the reality may be very different. Here, we present existing research on the impact of diverse dolls on children's play and psychology to argue that the dolls' proposed benefits for children with alopecia and vitiligo are unlikely to materialize; rather, alopecia and vitiligo Barbie could prove more harmful than beneficial.

Demodex positive discoid lupus erythematosus: Is it a separate entity or an overlap syndrome?

Discoid lupus erythematosus (DLE) is a chronic inflammatory erythematous skin disease that can be triggered by several factors. Rosacea is another skin disease that causes facial redness and tenderness. Demodex mites have been reported in rosacea and DLE patients commonly in the literature. These two diseases can be seen concomitant, mimic each other clinically and share common possible etiologic factors. To assess demodex mite infestation in both clinical and histopathological findings in DLE patients. We retrospectively evaluated the files of 42 patients with DLE who had been diagnosed DLE based on clinical and histopathological findings between August 2018 and August 2019. Demodex positivity was detected 50% of patients (n = 21). Neutrophile percentages in the dermal and perivascular area were higher in the demodex positive patients (4.43%) than in the Demodex negative patients (2.19%). The intensity of demodex mites correlated positively with dermal neutrophile percentages. ANA was negative in 29 patients (69%) and positive in 13 patients (31%). Anti-dsDNA was negative in serology and follicular plugging was positive in histopathology in all 42 patients (100%). This was a retrospective study. DLE and rosacea share common features in etiopathogenesis and clinical presentation. Inflammation and exacerbations caused by the demodex mites may increase the clinical severity of DLE. Although the position of demodex mites in DLE etiopathogenesis is not known exactly, the presence of high demodex in DLE patients has been determined. Standard skin surface biopsy can be a routine procedure for the evaluation of DLE patients in daily clinical practice.

Fasciite nodular na fronte: uma rara apresentação / Nodular fasciitis in the forehead: a rare presentation

A fasciite nodular é um tumor benigno, decorrente da proliferação reativa de células fibroblásticas ou miofibroblásticas de rápido crescimento e rica celularidade. Em adultos, o acometimento das extremidades é mais frequente; entretanto, outras regiões podem ser acometidas. Neste relato, é apresentada paciente feminina de 40 anos, com lesão nodular na fronte, com diagnóstico de fasciite nodular confirmado à histopatologia. O caso relatado procura destacar sua rara localização e alertar o dermatologista clínico para a sua inclusão entre os diagnósticos diferenciais das lesões tumorais na face.

Nodular fasciitis is a benign tumor resulting from the reactive proliferation of fibroblastic or myofibroblastic cells presenting rapid growth and rich cellularity. In adults, the extremities' involvement is more frequent; however, other regions can be affected. In this report, we present the case of a 40-year-old woman with a nodular lesion on the forehead. The histopathology confirmed the diagnosis of nodular fasciitis. The reported case highlights its rare location and alerts the clinical dermatologist in its inclusion among the differential diagnoses of tumor lesions on the face.

Predictive Model for Differential Diagnosis of Inflammatory Papular Dermatoses of the Face.

BACKGROUND: The clinical features of inflammatory papular dermatoses of the face are very similar. Their clinical manifestations have been described on the basis of a small number of case reports and are not specific. OBJECTIVE: This study aimed to use computer-aided image analysis (CAIA) to compare the clinical features and parameters of inflammatory papular dermatoses of the face and to develop a formalized diagnostic algorithm based on the significant findings. METHODS: The study included clinicopathologically confirmed inflammatory papular dermatoses of the face: 8 cases of eosinophilic pustular folliculitis (EPF), 13 of granulomatous periorificial dermatitis-lupus miliaris disseminatus faciei (GPD-LMDF) complex, 41 of granulomatous rosacea-papulopustular rosacea complex (GR-PPR) complex, and 4 of folliculitis. Clinical features were evaluated, and area density of papular lesions was quantitatively measured with CAIA. Based on these variables, we developed a predictive model for differential diagnosis using classification and regression tree analysis. RESULTS: The EPF group showed lesion asymmetry and annular clusters of papules in all cases. The GPD-LMDF complex group had significantly higher periocular density. The GR-PPR complex group showed a higher area density of unilateral cheek papules and the highest total area density. According to the predictive model, 3 variables were used for differential diagnosis of the 4 disease groups, and each group was diagnosed with a predicted probability of 67%~100%. CONCLUSION: We statistically confirmed the distinct clinical features of inflammatory papular dermatoses of the face and proposed a diagnostic algorithm for clinical diagnosis.

[A case report of granuloma faciale, an uncommon cutaneous vasculitis]. / Reporte de caso de granuloma facial, una vasculitis cutánea infrecuente.

Granuloma faciale is an uncommon benign dermatosis, with unknown etiology, usually asymptomatic, characterized by chronic inflammation localized in sun-exposed areas of the face with a characteristic histological pattern. Although response to treatment is variable, there are multiple therapeutic alternatives that have been reported to be effective in some patients, including systemic treatments with steroids and dapsone or also topical treatments like intralesional corticosteroid, cryotherapy and calcineurin inhibitors, such as tacrolimus. We present the case of an adult patient with an asymptomatic erythematous-violet plaque on the right cheek, with progressive slow growth over two years, clinically and histologically and pathologically compatible with a facial granuloma. The patient responded well to intralesional corticosteroids.

El granuloma facial es una dermatosis benigna poco frecuente de etiología desconocida, generalmente asintomática, caracterizada por inflamación crónica y localizada habitualmente en zonas fotoexpuestas de la cara, con un patrón histológico característico. Si bien la respuesta al tratamiento es variable, existen múltiples opciones terapéuticas que han reportado ser efectivas en algunos pacientes. Entre estas alternativas se incluyen tratamientos sistémicos con corticoides y dapsona o tratamientos intralesionales con corticoides, crioterapia e inhibidores de calcineurina tópicos. Describimos el caso de un paciente adulto con una placa eritemato violácea asintomática en mejilla derecha, de crecimiento lentamente progresivo de dos años de evolución, clínica e histopatológicamente compatible con granuloma facial y respuesta favorable a corticoides intralesionales.
