RESUMO
Monkeypox, an endemic disease in some African countries, has provoked public health activeness on a global scale that even the World Health Organization (WHO), invoking international health regulations, declared it a public health emergency of international concern (PHEIC). The WHO called attention of member states to exert maximum surveillance over the disease, its patients, and contact persons in order to standardize control measures. A need was directed to provide complete knowledge about the disease, allowing the administration of prior diagnoses as well as isolation and more effective epidemiologic control measures. An updated review on monkeypox emphasized upon having the fundamental aspects of the lesions caused by the disease, and appropriate management of patients upon clinical and epidemiologic evaluation.

The use of enzyme hyaluronidase to treat the complications of different brands of hyaluronic acid (HA) dermal fillers is increasing in the same proportion as the number of nonsurgical cosmetic procedures. Guidelines for diagnosing and treating complications remain controversial and are primarily based on anecdotal reports and small case series. We proposed approaching HA-related complications based on our clinical research and observations of treating more than 200 patients and providing a practical guide for the thoughtful use of hyaluronidase according to adverse events. Standardization of hyaluronidase dose and concentration is beneficial for better outcomes and future comparative analyses of the results of this treatment worldwide. The use of hyaluronidase is increasing for the reversal of the clinical manifestations of complications caused by HA fillers, although a consensus is lacking. We propose using different doses and concentrations of hyaluronidase to focus on selected anatomic areas considering properties of the product and pathogenesis of each complication.
RESUMO
The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux®, the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux® who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors.

A 60-year-old black man, working in construction sector, was referred to dermatology clinic for having multiple hardened and asymptomatic tumors on the scalp, face, and trunk for more than 40 years. There was a progressive increase in the number and size of lesions, causing significant aesthetic and functional impairment. In his family history, a son had numerous normochromic papules on the centrofacial region with a diagnosis of multiple trichoepithelioma. The deceased mother of our patient presented lesions similar to those of her grandson but without a confirmatory diagnosis. (SKINmed. 2023;21:47-50).

Keloids and hypertrophic scars are abnormal responses to wound-healing. While hypertrophic scars remain limited to the areas of trauma, keloids most often develop over several years, growing out from the limits of the initial wound area. Both lesions may cause itching, burning, and pain, and they may lead to significant impairment of self-esteem, socialization, and quality of life. Although they might be observed in all races, they are far more common in Africans and African descendants than in Caucasians.We extensively reviewed their treatment, including compression with pressure garments, occlusion with siliconized and non-siliconized gel sheets, gels, corticosteroid and antineoplastic injections, and the use of lasers and intense pulsed light (IPL) therapy. We also reviewed new therapies, including botulinum toxin injection, and addressed outcomes of various studies. (SKINmed. 2022;20:432-443).

A 47-year-old woman who lived in the metropolitan area of Rio de Janeiro and had abandoned her Acquired Immune Deficiency Syndrome (AIDS) therapy 3 years prior, was admitted to our hospital due to weight loss, cough, and fever for 2 weeks. The dermatologic examination established normochromic papules with molluscum-like central umbilication on the face (Figure 1) and hands, erythema and infiltration in the oral cavity (Figure 2), desquamative patches on the legs, and ulceration on right calcaneus (Figure 3). Her CD4 (T-cells) count was 47 cells/ mm.3 Direct mycology examination and cultures for several agents were performed. The mycology culture done from her skin and sputum grew Sporothrix 1 week after admission (Figure 4).

BACKGROUND: Acute Generalised Exanthematous Pustulosis (AGEP) is a rash with multiple sterile intraepidermal or subcorneal non-follicular pustules on edematous papules, with a sudden development and rapid evolution, triggered by drugs, vaccination, insect bites, exposure to mercury, and allergens. OBJECTIVES AND METHODS: We describe a female patient who developed extensive and abnormally prolonged AGEP following exposure to terbinafine and SARS-CoV vaccine. A detailed review of terbinafine-induced-AGEP cases was performed, with the aim of evaluating if the AGEP criteria would follow a different pattern when the disease is triggered by this drug. A PubMed search helped retrieve all terbinafine-induced AGEP case reports. AGEP-specific Sideroff criteria were analysed in terbinafine-induced cases and compared to other trigger causes. CONCLUSIONS: When the AGEP causative drug was terbinafine, a delay in recovery was observed, compared to the existing AGEP criteria when other causes are considered. Terbinafine frequently leads to delayed resolution AGEP probably due to the presence of the drug in the skin for several weeks after exposure, even after discontinuation, and the disease severity may be potentialised by additional factors such as concomitant viral infections or vaccination.

INTRODUCTION: The use of hyaluronic acid (HA) as a dermal filler is considered safe. However, as new brands come to the market, reports of adverse events are becoming more and more common. OBJECTIVE: To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA. METHODS: The report of four patients who presented this complication, and the occurrence of two HA syringes from the same batch that had hardened the product inside at the time of filling. CONCLUSION: The authors propose the nomenclature "happy bump" to group adverse reactions to HA that translate into noninflammatory nodules, with a stony consistency, appearing up to 4 weeks (recent) or after one month (late) in sites previously treated with AH.

BACKGROUND: Melasma is a common hypermelanosis characterized by symmetrical brownish macules, especially on the face. Histologic analysis demonstrates increased epidermal and dermal melanin. Dermoscopy is useful to estimate the depth of the melanin and may help in the diagnosis and classification of melasma, with therapeutic importance. OBJECTIVES: To evaluate the diagnostic concordance of dermoscopic classification of epidermal or mixed subtypes of melasma and the correlation between dermoscopic and histopathological findings. METHODS: Twenty-eight women with facial melasma, phototypes III to V, ages between 30 and 61 years were selected. Based on the evaluation of clinical and dermoscopic images, two independent observers classified melasma into epidermal or mixed subtypes. The intra and interobserver concordances were calculated. Histopathological analysis of epidermal melanin extension and maximum number of melanophages per high-power field (400×; HPF) have been assessed. Association between the melanophages count and the dermoscopic classification was evaluated. RESULTS: Intraobserver agreement was 82.1%, and between observers, from 78.6% to 89.3%, according to the Kappa index. Histopathology revealed increased intraepidermal melanin and the presence of dermal melanophages in all the samples. Ten or more melanophages/HPF was significantly associated with mixed melasma. CONCLUSIONS: Moderate to substantial concordance in the dermoscopic classification of melasma was found, and the correlation between this classification and the dermal melanophages count have been suggested. Intradermal component of every case of melasma should be considered for therapeutic and prognostic purposes.

BACKGROUND: In recent years, fillers procedures with hyaluronic acid (HA) have grown significantly. Despite HA relative safety, the number of cases of complications after injections has grown, and in many of which, we are not aware of or have little control over. AIMS: In this article, the authors describe a new adverse reaction after filling with HA injection, the sterile abscess. PATIENTS/METHODS: We present eight patients with similar clinical, laboratory, and ultrasound characteristics for sterile abscess and report a new therapeutic modality for it. RESULTS: All cases were treated with "Munhoz-Cavallieri Lavage Protocol" procedure with complete resolution. CONCLUSIONS: "Munhoz-Cavallieri Lavage Protocol" serves as a guideline in diagnosis and management of sterile abscess.

BACKGROUND: Psoriatic disease (PD) is a chronic inflammatory disorder often associated with cardiovascular risk (CVR) factors such as obesity, hypertension, diabetes, dyslipidaemia and smoking. It is estimated that 2%-4% of the population worldwide has PD. Cutaneous lesions of psoriasis (PsO) may be associated with psoriatic arthritis (PsA) in up to 40% of patients. Studies have been carried out around the world with the aim of evaluating CVR in such patients. AIM: To determine CVR in a multiracial population with PsA or PsO from southeastern Brazil, which has a predominantly tropical climate, compared with controls. METHODS: A cross-sectional study was carried out in outpatients with PsO or PsA followed up at a quaternary referral hospital in Rio de Janeiro. The Framingham Risk Score (FRS) was used to predict cardiovascular events (CVEs) over 10 years in patients with PsO and PsA compared with controls. RESULTS: FRS was significantly higher at 10 years in patients with PsO (mean ± SD 16.3 ± 14) and PsA (18.0 ± 15) compared with controls (10.6 ± 9.5) (P = 0.01) and also increased with age. The chance of having a high FRS in the PsO and PsA groups increased by 0.30 and 0.23 times per year, respectively, compared with controls (PsO vs. controls 95% CI 0.090-1.00; PsA vs. controls 95% CI 0.08-0.75). CONCLUSION: In this multiethnic Brazilian population, both PsO and PsA were associated with higher CVR compared with controls. The frequency of high FRS was highest in the sixth decade of life for all three groups of participants. Annual assessment of patients with PD is necessary in order to prevent CVEs.

Cutaneous horn is a protuberance constituted by compact keratinous material, with a hard consistence similar to a horn, which occurs more frequently in photoexposed areas. The authors describe a case of cutaneous horn on the glans considered a rare location. Verrucous carcinoma was the histopathological diagnosis of the base of the horn and lichen sclerosis, the precursor lesion.
RESUMO
Tuberous sclerosis is a rare autosomal dominant genetic disorder. It is characterized by the appearance of benign tumors, known as hamartomas, which can affect multiple organs, including the skin. Cutaneous manifestations are present in almost all patients; therefore, the dermatologist has a fundamental role in the history and evolution of the disease in spite of being a multisystemic disorder. Two tumor suppressor genes, CET1 and CET2, involved in tissue growth and cell proliferation, show mutation in this disease, which leads to the appearance of various benign tumors, hamartomas. Clinical characteristics are more than three hypomelanotic macules, more than three angiofibromas or face or scalp cephalic fibrotic plaque, more than two ungual fibromas, shagreen plaque, multiple retinal hamartomas, etc. Treatment is basically symptomatic, and genetic counseling is very important. This is an autosomal dominant disorder, although there is spontaneous mutation and no familial history in 65% of patients. When one of the parents is affected, genetic study is useful for prenatal diagnosis.

BACKGROUND: Epidemiological studies indicate that onychomycosis may affect up to 79% of psoriatic patients. Onychomycosis in psoriatic patients is more commonly caused by yeasts comparing with non-psoriatic. OBJECTIVES: Evaluate the prevalence of fungi in nail psoriasis. Evaluate the association between direct mycological examination (DME) and mycological culture, Nail Psoriasis Severity Index (NAPSI) and systemic treatment for psoriasis. METHODS: Of 133 nails from 20 patients with nail psoriasis were evaluated as follows: 9 patients were using topical treatment and 11 were on systemic treatment. The assessment of psoriasis severity using NAPSI was performed in all psoriatic nails. The presence of fungi was confirmed in DME and culture. RESULTS: DME showed the presence of fungal elements in 45 nails (33.83%) with a predominance of blastoconidia (95.5%) No septate hyphae were seen. Mycological culture was positive in 36 (27.06%) samples. Among them, Candida grew in 31 (86.1%): Candida parapsilosis in 15 (48.38%), Candida spp in 14 (45.16%). No growth of dermatophytes was observed. Patients with systemic treatment showed a higher frequency of positive test (DME and culture) for fungi when compared to topic treatment (p:.006). There was a positive correlation between NAPSI, mycological culture and systemic treatment (p:.0063); the risk was four times higher (OR:4.0). LIMITATION OF THE STUDY: Sample size. CONCLUSION: These results are consistent with some previous reports, Candida was the fungus with higher frequency on the psoriatic nails, however, the role of these fungi is controversial (contamination x colonisation x infection). The fact that the immunosuppressive treatment increases the chance of fungal infection leads us to a greater attention to this patient profile, to prevent the intensification of nail psoriasis (Köbner phenomenon).

BACKGROUND: The study of HLA classes I and II in Brazilian psoriasis patients may contribute to a better understanding of their association with the disease. OBJECTIVE: To describe HLA classes I and II of Brazilian patients with psoriasis, with or without arthritis, compare them to controls and correlate HLA markers with epidemiological and evolutional aspects of psoriasis. METHODS: A total of 55 patients with more than 5 years of psoriasis, with or without arthritis, answered a questionnaire on ethnic background and disease severity. A total of 134 bone marrow donors were controls. HLA class I and II genotyping was determined by PCR-SSP. RESULTS: Mean age was 42.4 years; 23 women and 32 men. HLA-B*57 was present in 23.6% patients and in 7.5% controls (p=0.00200, OR= 3.8381), and HLA-C*06 in 29.1% patients and in 16.4% controls (p= 0.04832, OR=2.0886). HLA-B*57 and HLA-C*18 were significantly present in patients with arthritis (p=0.00104, OR=6.6769 and p=0.00269, OR=16.50, respectively). HLA-B*57 was significantly present in patients with history of erythroderma (p=0.00548, OR= 5.1059), as was HLA-C*06 (p=0.02158, OR=3.0545). HLA-B*57 was also frequent in patients with history of hospital internment due to psoriasis (p= 0.00094, OR=7.8909) and in the ones with history of systemic treatment for psoriasis (p= 0.00011, OR= 5.3733). Haplotype HLA-A*02 B*57 C*06 DRB1*07DQB1*03 was the most common among the patients (p= 0.00069, OR= 3.528). CONCLUSION: HLA-B*57 and HLA-C*06 were significantly increased in the patients indicating risk for psoriasis. HLA-B*57 remained high in patients with history of erythroderma, hospital internment, systemic treatment, and psoriatic arthritis, showing association with disease severity. HLA-C*18 was significantly high only in patients with psoriatic arthritis. HLA-B*57 and HLA-C*06 and haplotype HLA-A*02B*57Cw*06DRB1*07 DQB1*03 seen in this study were already described before, associated with psoriasis. HLA-Cw*18 was not described in other populations in association with psoriasis.
RESUMO
BACKGROUND: Facial filling based on hyaluronic acid (HA) is an esthetic procedure that is widely performed worldwide. METHODOLOGY: Fifty patients underwent facial filling based on HA, and 10 board-certified dermatologists evaluated clinical photographs before and after the procedure and completed a questionnaire to provide information about the procedure. RESULTS: All doctors and 96% of patients were agreed about the pre- and postprocedural photographs. Physicians were more aware of the possibility of frequent pain and erythema. Both groups showed agreement in their responses on the following topics: the possibility of hematoma and edema, a lack of secretion, improvement in patients' self-confidence, recognition of the procedure by third parties, and knowledge of the procedure by the dermatologists themselves. However, physicians tend to overestimate the possibility of erythema, pain, and edema; they also tend to minimize the duration and discomfort of postprocedural edema and the risk of third parties noticing patients' HA filling and how much it bothers patients when third parties do notice. CONCLUSION: Doctors and patients disagree on some questions about what actually happens and what is supposed to happen in facial filling procedures based on HA.
