ABSTRACT

Vitiligo is a dermatological disease affecting both animals and humans. It is characterized by depigmented macules of varying shape and size, originated from melanocyte destruction. Even though there are some theories tackling causation, disease etiopathology is not yet certain. Moreover, lesion areas can either increase or diminish over time, and therefore, available treatment alternatives tend to prove inconsistencies. No epidemiological data or registered cases were found for equines in Brazil. The horse in this case description displayed depigmentation areas in facial regions, including upper lip, nose and lips. However, the individual did not happen to develop any systemic alteration. Through clinical evaluation, backed by a histopathological exam, a definitive vitiligo diagnosis was obtained. However, no therapeutic plan was stipulated. The animal was accompanied for four years, during which period some affected areas diminished while others increased in size. In addition, emergence of new skin lesions was also observed during the time the animal was studied. Overall, this disease does not display alterations to organism functionality, only aesthetic changes. Therefore, treatment plans may vary from case to case, occasionally being even ruled out.(AU)


O vitiligo é uma doença dermatológica que pode afetar animais e humanos. Caracteriza-se por áreas despigmentadas, de formas e tamanhos variáveis, que surgem devido a destruição dos melanócitos. Existem algumas teorias que tentam explicar a etiopatogenia da doença, entretanto ainda não é totalmente esclarecida. As lesões podem aumentar ou diminuir com o tempo, por isso os tratamentos disponíveis são inconsistentes. Não foram encontrados dados epidemiológicos ou relatos de vitiligo em cavalos no Brasil. O equino deste relato apresentava lesões despigmentadas na região da face, incluindo pálpebras, narina e lábios, sem alterações sistêmicas. Por meio da avaliação clínica em conjunto com o exame histopatológico obteve-se o diagnóstico definitivo de vitiligo. Não foi instituído nenhuma terapia, e o equino foi acompanhado durante quatro anos. Durante esse período algumas lesões diminuíram e outras aumentaram de tamanho sendo também observado o aparecimento de novas lesões. O vitiligo não traz alterações sistêmicas, apenas mudanças estéticas, por isso a escolha pelo tratamento dependerá de cada caso.(AU)

ABSTRACT

RESUMO A íris é responsável pela cor dos olhos. Ela ainda realiza o controle da quantidade de luz que penetra no olho pela pupila. Variações nos genes de cada indivíduo, além da quantidade e da qualidade de melanina na íris, determinam a cor dos olhos. A heterocromia é caracterizada por diferenças na coloração da íris de um mesmo indivíduo, sendo, na maioria das vezes, benigna. Existem basicamente três tipos de heterocromia de íris: central, setorial e completa. A heterocromia de íris pode ter como causa alterações genéticas e congênitas, relacionadas ou não a síndromes específicas, como a de Sturge-Weber, a de Waardenburg, a de Parry-Romberg e a de Horner congênita. Há também causas adquiridas, como doenças ou lesões, trauma ocular e corpos estranhos intraoculares, uso de certas medicações tópicas, siderose ocular, irites ou uveítes como a síndrome uveítica de Fuchs, dentre outras. Diante de um paciente com heterocromia de íris, deve-se entender o contexto e o curso clínico desse sinal, pois pode se tratar de uma alteração de pigmentação benigna ou existir uma doença base em curso, que requer terapêutica específica. Este artigo de revisão de literatura visa abordar as principais etiologias relacionadas à heterocromia de íris, além de discorrer sobre a anatomia e a fisiologia da coloração iridiana e sobre a fisiopatologia de suas possíveis alterações.


ABSTRACT The iris is responsible for eye color and controls the amount of light that enters the eye through the pupil. Variation in each individual's genes, besides the quantity and quality of melanin in the iris, determine eye color. Heterochromia is characterized by different colors of irises in the same individual, and it is benign in most cases. There are basically three types of heterochromia: central, partial and complete. Heterochromia can be caused by genetic and congenital alterations, which may or may not be related to specific conditions, such as Sturge-Weber syndrome, Waardenburg syndrome, Parry-Romberg syndrome and congenital Horner syndrome. It may be associated to acquired causes like diseases or injuries, such as eye trauma and intraocular foreign bodies, use of some topical medications, ocular siderosis, iritis or uveitis, such as Fuchs´ uveitis, among others. When assessing a patient with heterochromia, one must understand the context and clinical course of this signal, since it may be a benign pigmentation disorder or there may be an underlying disease, which requires specific therapy. This literature review article was set out to address the main etiologies related to heterochromia, in addition to describing the anatomy and physiology of the iris color and the pathophysiology of possible alterations.

ABSTRACT

Las pigmentaciones de la cavidad oral son comunes, éstas pueden representar diversas entidades clínicas, desde cambios fisiológicos hasta cambios malignos. Las pigmentaciones en la encía se conocen como pigmentaciones melánicas o melanosis gingival; en la encía se observan como tinciones oscuras ocasionadas por la acumulación de melanina en la zona. Éstas se consideran comunes, pueden representar variación normal en la pigmentación de melanina de la mucosa oral, hasta representar procesos malignos. En general, las personas de piel más oscura presentan frecuentemente mayor pigmentación de melanina oral que las personas de piel clara. Las variaciones en la pigmentación fisiológica oral están determinadas genéticamente a menos que estén asociadas con alguna enfermedad subyacente (AU)


Pigmentation of the oral cavity is common, it can represent diverse clinical entities, from physiological changes to malignant changes. Gum pigmentations are known as melanic pigmentations or gingival melanosis, and are observed as dark stains caused by the accumulation of melanin in the localized area. These are considered common, they can represent normal variation in melanin pigmentation of the oral mucosa, or malignant processes. In general, people with darker skin often exhibit greater pigmentation of oral melanin than people with fair skin. Variations in oral physiological pigmentation are genetically determined unless they are associated with some underlying disease (AU)

ABSTRACT

OBJECTIVE@#To detect variants of ADAR1 gene in two Chinese pedigrees affected with dyschromatosis symmetrica hereditaria (DSH).@*METHODS@#Clinical data and peripheral blood samples of the pedigrees were collected. All exons of the ADAR1 gene were amplified by PCR and subjected to Sanger sequencing. Suspected pathogenic variants were validated among other members of the pedigrees and 100 unrelated healthy controls.@*RESULTS@#For pedigree 1, Sanger sequencing has identified a heterozygous missense variant c.3002G>C (p.Asp968His) in exon 11 of the ADAR1 gene in the proband and his father. For pedigree 2, a novel nonsense variant c.3145C>T (p.Gln1049Ter) was identified in exon 12 of the ADAR1 gene in the proband and his son, which were previously unreported and absent among the healthy controls.@*CONCLUSION@#The c.3002G>C (p.Asp968His) and c.3145C>T (p.Gln1049Ter)variants of the ADAR1 gene probably underlay the DSH in the two pedigrees.

ABSTRACT

OBJECTIVE@#To detect mutations of ADAR gene in two pedigrees affected with dyschromatosis symmetrica hereditaria (DSH).@*METHODS@#Potential mutations of the ADAR gene were analyzed by Sanger sequencing of the probands from both pedigrees. Suspected mutations were validated by Sanger sequencing of other patients from both pedigrees as well as unrelated healthy individuals.@*RESULTS@#A heterozygous nonsense mutation c.1325C>G (p.Ser442Ter) and a novel nonsense mutation c.1498C>T (p.Gln500Ter) were respectively identified in the ADAR gene among all patients from the two pedigrees but not among 200 healthy individuals.@*CONCLUSION@#Mutations of the ADAR gene probably underlie the DSH in the two pedigrees. Above findings have enriched the spectrum of ADAR gene mutation.

ABSTRACT

Hypomelanosis of Ito (HI) is a neurocutaneous disorder, also known as incontinentia pigmenti achromians. HI has been associated with chromosomal abnormalities, especially mosaicism. Herein, we report a case of HI with multiple congenital anomalies. A 2-month-old girl presented with multiple linear and whorling hypopigmentation on the face, trunk, and both extremities and patch alopecia on the scalp. Moreover, she had conical teeth, aniridia of the both eyes, and multiple musculoskeletal problems, including syndactyly and coccyx deviation. Cytogenetic analysis on peripheral blood was normal 46, XX, and no mutation was found in IKBKG gene test.

ABSTRACT

OBJECTIVE@#To explore the genetic etiology of two unrelated patients with dyschromatosis symmetrica hereditaria.@*METHODS@#Variant analysis of the ADAR gene was carried out by Sanger sequencing.@*RESULTS@#Patient 1 was found to harbor a c.2633_2634delCT (p.Ser878fs) in exon 8 of the ADAR gene. The same variant was not found among 100 unrelated individuals. No pathogenic variant of the ADAR gene was found in patient 2. Functional prediction of the ADAR c.2633_2634delCT (p.Ser878fs) variant indicated it to be pathogenic by losing a catalytic structural domain.@*CONCLUSION@#The c.2633_2634delCT (p.Ser878fs) variant of the ADAR gene probably underlies the pathogenesis of DSH in one of the patients.

ABSTRACT

Introduction: la dermatoscopie est une technique d'examen non invasive, permettant de donner un nouveau regard de la morphologie clinique des lésions pigmentées et des tumeurs cutanées. Nous montrons à travers notre série les caractéristiques morphologiques dermotoscopiques du carcinome basocellulaire (CBC) chez notre population.Méthodes: notre étude est une étude prospective unicentrique étalée sur une période de 2 ans. Nous avons utilisé le dermoscope chez tous les patients ayant un CBC. L'analyse statistique était réalisée à 'aide du logiciel SPSS version 17.Résultats: on avait recensé 100 CBC, L'âge moyen des patients était de 51,87 ans, avec un sex ratio F/H = 0,6. Le visage était la localisation la plus fréquente et la plupart des patients étaient de phototype III et IV. On a distingué des critères dermatoscopiques classiques et non classiques. On a montré qu'il existe une relation significative entre le phototype et le degré de la pigmentation des CBC. Conclusion: dans ce présent travail, le dermoscope était bénéfique d'une part pour détecter les CBC de petite taille, d'autre part pour faciliter le diagnostic des CBC pigmentés

ABSTRACT

Introducción: la incontinencia pigmenti es una genodermatosis rara ligada al cromosoma X, afecta al sexo femenino y tiene diferentes expresiones clínicas en una misma familia. Presentación del caso: preescolar de 20 meses de edad, con antecedente familiar de incontinencia pigmenti, que presentó lesiones típicas en la piel desde la primera semana de vida, de aspectos lineales, vesículo-costro-ampollosas, verrucosas, y luego hiperpigmentadas, en diferentes fases y múltiples brotes. Comienza desde el primer mes de vida con crisis epilépticas que evoluciona a una encefalopatía de West, con buena respuesta a la vigabatrina y control de los espasmos infantiles. Conclusiones: la incontinencia pigmenti se caracteriza por afectar, de forma variable, a los tejidos derivados del neuroectodermo, la piel y otras faneras, ojos y el sistema nervioso central, provoca daño multisistémico. Las lesiones de la piel son las más significativas desde el nacimiento, y la biopsia de piel confirma el diagnóstico(AU)


Introduction: incontinentia pigmenti is a rare genodermatosis linked to the X chromosome. It affects the female sex and has different clinical manifestations in the same family. Case presentation: a 20-month-old infant with a family history of incontinentia pigmenti, who from the first week of life presented typical lesions on the skin of linear, vesicular-crust-bullous, warty, and then hyperpigmented aspects, in different phases and multiple outbreaks. From the first month of life, the patient presented epileptic seizures that evolved to West encephalopathy, with good response to vigabatrin and control of infantile spasms. Conclusions: incontinentia pigmenti is characterized by affecting, in a variable way, the tissues derived from the neuroectoderm, the skin and other skin´s structures, the eyes and the central nervous system causing multisystem damage. Skin lesions are the most significant since birth, and skin biopsy confirms the diagnosis(AU)

ABSTRACT

Abstract: Purpura is defined as a visible hemorrhage in the skin or mucosa, which is not evanescent upon pressure. Proper classification allows a better patient approach due to its multiple diagnoses. Purpuras can be categorized by size, morphology, and other characteristics. The course varies according to the etiology, as do the diagnostic approach and treatment. This review discusses pigmented purpuras and some cutaneous vascular occlusion syndromes.

ABSTRACT

Acquired brachial cutaneous dyschromatosis (ABCD) is an acquired disorder of pigmentary change that presents as chronic, asymptomatic, geographic-shaped, gray-brown patches, consisting of mixed hyper and hypopigmented macules on the dorsal aspect of the forearms. We report a case of a 40-year-old male who presented with asymptomatic, multiple brown-colored macules on the outer aspects of both arms. He had no history of hypertension and had never taken angiotensin converting enzyme inhibitors. He also denied chronic sun exposure history. Histologic examination demonstrated epidermal atrophy, increased basal layer pigmentation, and several telangiectatic vessels in the upper dermis. Solar elastosis was not remarkable. The patient's clinical and histopathologic features were consistent with a diagnosis of ABCD. Poikiloderma of Civatte, melasma, acquired bilateral telangiectatic macules and other pigmentary disorders should be considered in the differential diagnosis of ABCD. Herein, we report a case of ABCD in a middle-aged male without hypertension and medication.

ABSTRACT

The aim of this study was to develop and evaluate a corrective and photoprotective makeup for patients with dyschromias. An emulsion was prepared and pigment mixtures were incorporated in the formulation, producing five shades of corrective makeup: BEIGE (I, II, III), BRONZE and TAN. The sun protection factor (SPF) and UVA/UVB ratio of the corrective makeup were determined using spectrophotometry with a Labsphere® analyser. The spreadability, occlusivity, stability, and photostability of the photoprotective formulations were also evaluated. For all formulations there was no statistical difference among them (p > 0.05) in terms of spreadability, occlusivity and SPF. They were considered to be photostable under solar radiation, with variations in SPF value and UVA/UVB ratio lower than 20%. The corrective makeup presented average-to-high UVB photoprotection and broad spectrum photoprotection. After 90 days, pH, density and SPF values showed no significant differences among formulations (p>0.05). All corrective makeup presented separation of the pigments, however, they returned to a homogeneous aspect and to the original color shade after shaking. The corrective makeup presented a fine texture, little brightness, and a homogeneous, dry-to-the-touch aspect. This work may benefit patients with dyschromias, improving their quality of life, besides promoting photoprotection and covering the skin blemishes

ABSTRACT

A Hipercromia pós-inflamatória (HPI), desordem de pigmentação da pele decorrente da produção exagerada de melanina, apresenta-se sob a forma de manchas hipercrômicas e representa uma sequela importante da psoríase, uma dermatose inflamatória. Objetiva-se, neste artigo, um relato de caso, descrever a HPI surgida após um quadro de psoríase, em paciente do gênero masculino, 54 anos de idade, cor parda, marceneiro de profissão, sem histórico de tabagismo, obesidade ou doença de base, atendido em uma Unidade Estratégia Saúde da Família (ESF), no município de Vassouras, região Centro Sul do Estado do Rio de Janeiro. A psoríase é uma doença imunológica crônica, resultante da estimulação persistente de células T por imunógenos de origem epidérmica, envolvendo a imunidade inata e a adquirida. A conduta terapêutica da HPI incluiu a prescrição de corticosteróides, despigmentantes e fotoprotetores. O acompanhamento do paciente por psicoterapia do Núcleo de Apoio à Saúde da Família (NASF), da ESF e pelo dermatologista da média complexidade da Rede de Atenção à Saúde (RAS) representou um diferencial e revelou-se imprescindível para a integralidade do cuidado em saúde.(AU)


Post-inflammatory hyperchromia (IPH), a pigmentation disorder of the skin resulting from the exaggerated production of melanin, is manifested by hyperchromic patches and is an important consequence of psoriasis, an inflammatory dermatosis. The objective of this article is to describe a case of IPH that appeared after psoriasis in a patient attended at a Family Health Strategy Unit (FHU), in the city of Vassouras, in the central region of the State of Rio de Janeiro. Psoriasis is a chronic immune disease that results from the persistent stimulation of T cells by immunogens of epidermal origin, involving innate and acquired immunity. The therapeutic management of IPH consists in prescribing of corticosteroids, despigmentants and photoprotectors. The follow-up of the patient through Psychology of the Family Health Support Center, the FHU and the dermatologist of the medium complexity of the Health Care Network represented a differential and proved to be essential for the integrality of health care.(AU)
