Skin manifestations associated with COVID-19

Abstract This article will address the main aspects of skin manifestations associated with COVID-19, based on a review of the literature published to date. Since the beginning of the pandemic, more than 1,500 articles have been published on the subject. Regarding the pathophysiology, it is believed that the same mechanisms responsible for the disease in the main target organs also act in the skin, although they are not yet fully elucidated. The actual frequency of dermatological manifestations remains uncertain - it can range from 0.2% to 45%, being close to 6% in systematic reviews. Pioneering studies of large case series conducted in European countries and the USA provide the first information on the main skin manifestations associated with COVID-19 and propose classifications regarding their clinical presentation, pathophysiology, as well as their frequencies. Although there is yet no consensus, maculopapular eruptions are considered the most frequent presentations, followed by erythema pernio-like (EPL) lesions. Manifestations such as urticaria, vesicular conditions and livedo/purpura/necrosis are rare. The time of onset, severity, need for specific treatment and prognosis vary according to the clinical presentation pattern. The increasing histopathological description of skin conditions can contribute to the diagnosis, as well as to the understanding of the pathophysiology. Also, in the dermatological field, the relationship between COVID-19 and androgens has been increasingly studied. Despite all the generated knowledge, the actual biological meaning of skin manifestations remains uncertain. Therefore, the exclusion of the main differential diagnoses is essential for the correlation between skin manifestation and COVID-19.

Papilomatosis confluente y reticulada de Gougerot-Carteaud / Confluent and reticulated papillomatosis of Gougerot-Carteaud

La papilomatosis confluente y reticulada es una dermatosis infrecuente, benigna, de curso crónico y etiopatogenia desconocida. Actualmente, se acepta que se debe a un trastorno de la queratinización. Se caracteriza por máculas y pápulas hiperpigmentadas, que coalescen en el centro y adoptan un patrón reticular en la periferia. Se la puede confundir con otras patologías, como la pitiriasis versicolor y la acantosis nigricans. Con la administración de minociclina por vía oral suelen obtenerse excelentes resultados. Se comunica el caso de un paciente con diagnóstico de papilomatosis confluente y reticulada. Se describen sus características clínicas, criterios diagnósticos y trata-miento instaurado.

Confluent and reticulated papillomatosis is an infrequent, benign dermatosis of chronic course and unknown etiopathogenesis. Currently it is accepted that this dermatosis is due to a keratinization disorder. It is characterized by hyperpigmented macules and papules that coalesce in the center and adopt a reticular pattern in the periphery. It can be confused with other pathologies such as pityriasis versicolor and acanthosis nigricans. Oral minocycline usually shows excellent results. The present work reports a case of a patient with a diagnosis of confluent and retic-ulated papillomatosis, describing its clinical characteristics, diagnostic criteria and established treatment.

Lesiones en la piel causadas por ácaros de palomas / Skin lesions caused by bird mites

El prurigo agudo es una patología sumamente frecuente y con múltiples etiologías, entre las cuales se encuentran los ácaros de las aves. La incidencia de esta dermatosis ha aumentado en el último tiempo. Existen diferentes parásitos que colonizan las aves y que, al tener contacto con el ser humano, generan lesiones papulosas de tipo prurigo. El agente causal más involucrado es Dermanyssus gallinae, no siempre hallado en el momento del examen físico. Se presenta el caso de una mujer con lesiones papulosas en el tronco y las extremidades, iniciadas luego del contacto con detritos de palomas.

Acute prurigo is an extremely frequent dermatosis with multiple etiologies, including bird mites. Recently, there has been an increase in the reported cases of human infestation cases caused by bird acarus. Many parasites colonize birds and the infestation to humans produces papular lesions. Dermanyssus gallinae is the most common acarus involved. We report a woman with papular lesions in trunk and extremities after contact with a bird nest.

Pacientes con compromiso orbitario y renal: Diagnósticos diferenciales poco frecuentes / Patients with orbitary and kidney commitment: Rare differential diagnoses

Se comunica una serie de tres casos clínicos que consultaron al servicio de Reumatología por compromiso orbitario y renal. Uno de ellos presentó pseudotumor orbitario con proteinuria en rango nefrótico; se realizó biopsia y se encontró infiltrado linfoplasmocitario denso y fibrosis estoriforme con inmunohistoquímica: 15 células IgG4+ por campo de alto poder y relación IgG/IgG4 ≤40%, concluyendo diagnóstico de enfermedad relacionada por IgG4. El segundo y tercer caso presentaron compromiso ocular con "ojos de mapache" y lesiones amarillentas en párpados, ambos con proteinuria >500 mg/24 h, con biopsia de piel rojo Congo positiva y birrefringencia verde manzana con luz polarizada. Se discuten distintos diagnósticos diferenciales poco frecuentes a tener en cuenta en estos pacientes.

A series of three cases that consulted the rheumatology service due to orbital and renal involvement is reported. One of them presented orbital pseudotumor with proteinuria in the nephrotic range, a biopsy was performed, finding dense lymphoplasmacytic infiltrate and storiform fibrosis with immunohistochemistry: 15 IgG4 positive cells per HPF and IgG/IgG4 ratio ≤40%, concluding diagnosis of IgG4 related disease. The second and third cases presented ocular involvement with raccoon eyes and yellowish lesions on the eyelids, both with proteinuria greater than 500 mg/24 h, with apple-green birefringence of amyloid on congo red staining. Different rare differential diagnoses to take into account in these patients are discussed.

Urgencias dermatológicas. Estudio prospectivo y multicéntrico en Argentina / Dermatological emergencies. Prospective and multicentric study in Argentina

Resumen Las urgencias dermatológicas constituyen un motivo de consulta frecuente en los departamentos de urgencias. Con el objetivo de determinar la prevalencia de las consultas por urgencias dermato lógicas, describir las mismas, analizar la coincidencia entre los diagnósticos recibidos por los pacientes, en los casos que realizaron dos consultas por el mismo cuadro, y analizar el comportamiento de las variables de acuerdo al subsector del sistema de salud en el cual fueron atendidos: subsector público, y subsector privado, se realizó un estudio prospectivo, observacional, analítico, de corte transversal y multicéntrico. Se incluyeron 2801 pacientes. La prevalencia de las consultas por urgencias dermatológicas en adultos fue de 15% en el mismo período horario (subsector público: 10.6% y subsector privado: 22.5%, p < 0.05). Motivó la consulta una enfermedad infecciosa en el 35.5%, alérgica en el 29.6% y neoplásica en el 8.6%. Se hospitalizó el 0.7% de los pacientes. El 31.7% de los pacientes había realizado consultas previas. En estos casos se encontró coincidencia entre los diagnósticos realizados en el 80.7% de los atendidos de forma precedente por un médico dermatólogo, y el 52.6% de los evaluados por médicos no dermatólogos. La alta prevalencia de las consultas por urgencias dermatológicas y las diferencias existentes en la probabilidad de recibir un diagnóstico apropiado de acuerdo con la especialización del profesional interviniente, muestran la importancia de la presencia de un médico con formación en dermatología en el área de urgencias.

Abstract Dermatological emergencies are a frequent reason for emergency departments consultation. In order to determine the prevalence of dermatological emergencies, to describe the kind of dermatological diseases that present as emergencies, to analyze the coincidence between the diagnoses received by the patients in those cases with a previous consultations for the same cutaneous manifestation, and to analyze the behavior according to the health system segment in which they were attended: public segment and private segment; a prospective, ob servational, analytical, cross-sectional and multi-center study was carried out. Two thousand eight hundred one patients were included. The prevalence of consultations for dermatological emergencies in adults was 15% in the same time period (public segment: 10.6 and private segment: 22.5%, p < 0.05). The consultation was due to an infectious disease in 35.5%, allergic in 29.6% and neoplastic in 8.6%; 0.7% of patients were hospitalized. In 31.7% of patients who had a previous consultation, a coincidence was found between the diagnoses made in 80.7% of those attended by a dermatologist, and 52.6% evaluated by non-dermatologist physician. The high prevalence of dermatological consultations and the existing differences in the probability of receiving an appropri ate diagnosis according to the specialization of the intervening professional, show the importance of the presence of dermatology-trained physicians in the emergency area.

Lesões de pele diagnosticadas em búfalos (Bubalus bubalis) na região do baixo Amazonas / Skin injuries diagnosed in buffaloes (Bubalus bubalis) in the lower Amazon region

A pele é o maior órgão do corpo e pode ser acometida por uma série de processos patológicos. As doenças dermatológicas em geral são um aspecto frustrante na clínica de animais de grande porte. Desse modo, o objetivo deste estudo foi relatar lesões de pele diagnosticadas em búfalos na região do Baixo Amazonas, estado do Pará. Foram avaliados 156 búfalos das raças Murrah, Mediterrâneo e seus mestiços; adultos e jovens, com idade variando de oito meses a nove anos. No exame físico constatou-se que 36,5% (57/156) dos animais apresentavam abscessos no local de vacinação. Destes, 12,2% (19/156) eram abscessos com presença de alopecia e 1,3% (2/156) com fistulação Além disso, 1,3% (2/156) dos animais apresentaram ainda no local de vacinação, feridas ulceradas com presença de secreção purulenta. Identificou-se que 3,8% (6/156) dos búfalos possuíam lesões provenientes da marcação a fogo, com queimaduras, de aspecto crostoso, eritematoso e exsudativo, na região da garupa.; A maioria 64,1% (100/156) dos animais apresentaram corte das orelhas, 1,9% (3/156) apresentaram lesões por penetração de corno e em 1,2% (2/156) observou-se lesão de pele no membro posterior direito. Conclui-se que foi possível diagnosticar diversas lesões cutâneas nos búfalos na região do Baixo Amazonas, sendo o erro no manejo dos animais as principais causas das lesões diagnosticadas. Além disso, houve correlação entre dois grupos de animais avaliados (com e sem lesão).

The skin is the largest organ in the body and can be affected by a series of pathological processes. Dermatological diseases in general are a frustrating aspect in the clinic of large animals. Thus, the objective of this study was to report skin lesions diagnosed in buffaloes in the region of Baixo Amazonas, state of Pará. 156 buffaloes of the Murrah, Mediterranean and crossbred breeds were taken; Adults and young people, with ages varying from eight months to nine years. On physical examination, it was found that 36.5% (57/156) of the animals had abscesses at the vaccination site. Of these, 12.2% (19/156) were abscesses with the presence of alopecia and 1.3% (2/156) with fistulation. In addition, 1.3% (2/156) of the animals separated at the vaccination site, ulcerated wounds with the presence of purulent secretion. It was identified that 3.8% (6/156) of the buffaloes had the location of the fire mark, with burns, with a crusted, erythematous and exudative aspect, in the croup region. The majority 64.1% (100/156) of the animals separation of the ears, 1.9% (3/156) dissipation by penetration of the horn and in 1.2% (2/156) a skin lesion was observed in any limb posterior right. It was concluded that it was possible to diagnose several cutaneous lesions in buffaloes in the region of Baixo Amazonas, with the error in handling animals being the main causes of the diagnosed injuries. In addition, there was a correlation between two groups of acquired animals (with and without injury).

Unusual clinical manifestation of epidermoid cyst mimicking basal cell carcinoma / Presentación clínica inusual de quiste epidermoide imitando un carcinoma basocelular

Epidermoid cyst is a type of cutaneous cyst commonly found in daily practice. The facial area is the most common area for emergence of this benign condition. Simple extirpation is usually performed to remove epidermoid cysts. However, in rare cases, epidermoid cysts can evolve into malignancies such as basal cell carcinoma (BCC) or can mimic them, which adds difficulty when making a proper diagnosis. In cases of doubt, histopathology plays a key role in aiding diagnosis. This case report is about a 33-year-old woman with suspected nodular lesion that mimicked BCC, but after histopathological analysis was confirmed to be epidermoid cyst

El quiste epidermoide es un tipo de quiste cutáneo que se encuentra frecuentemente en la práctica diaria. El área facial es el área más común para la aparición de esta lesión benigna. La extirpación quirúrgica simple es el procedimiento habitual para eliminar los quistes epidermoides. Sin embargo, en casos raros, los quistes epidermoides pueden evolucionar en neoplasias malignas como el carcinoma basocelular (CCB) o pueden imitarlos, lo que añade dificultad al hacer un diagnóstico adecuado. En caso de duda, la histopatología desempeña un papel clave en la ayuda al diagnóstico. Este informe de caso trata sobre una mujer de 33 años con sospecha de lesión nodular que imitaba el CCB, pero después de que se confirmó con el análisis histopatológico, que se trataba de un quiste epidermoide.

History of dermatology: the study of skin diseases over the centuries

Abstract The study of skin, the science of dermatology, has undergone significant transformations throughout the centuries. From the first descriptions of skin diseases in Egyptian papyri and in Hippocratic writings to the first treatises on dermatology, important individuals and discoveries have marked the specialty. In the 18th and 19th centuries, the specialty consolidated itself as a field of medical study based on the first classifications of dermatoses, diagnostic methods, and drug treatments. In the 20th century, the scientific and technological revolution transformed dermatological practice, incorporating new therapeutic resources, as well as surgical and aesthetic procedures. In the face of such a vigorous process, it is important to provide a historical synthesis for the medical community to recognize and understand the origins that supported one of the most relevant specialties in the current medical scenario.

Melanoma: un desafío para el pediatra. Dos casos clínicos / Melanoma: A pediatric challenge. A two cases report

El melanoma es la forma más grave de cáncer de piel. La morbimortalidad es variable, ya que se relaciona con las medidas de prevención implementadas, la detección temprana y el acceso al tratamiento temprano. La incidencia ha aumentado en los últimos años a pesar de la mayor concientización con respecto a la exposición a la luz solar y la utilización de cremas protectoras. A su vez, el rango etario se ha ampliado, y esta enfermedad afecta a individuos cada vez más jóvenes. Se estima que del 1 % al 4 % de todos los casos de melanoma ocurren en menores de 20 años.Se presentan dos casos pediátricos, con evolución prolongada y diagnóstico inicial erróneo. Es fundamental para el pediatra general, primer contacto del paciente con el sistema de salud, conocer las características de estas lesiones. Un alto índice de sospecha permitiría la derivación al especialista de forma temprana.

Melanoma is the most serious skin cancer. Morbimortality is variable as it is related to the preventive measures, early detection, and access to early treatment. The incidence has increased in recent years, despite the raise in awareness of avoiding sun exposure and the use of sunscreen. What is more, the disease age range has expanded, affecting increasingly younger individuals. It is estimated that 1 to 4 % of all melanoma cases occurred in people younger than twenty years old.We present two pediatric cases with prolonged evolution and wrong initial diagnosis. Since the general pediatrician is the patient's first contact with the health system, it is extremely important to know the characteristics of these lesions. A high index of suspicion would allow an early referral to the specialist.

Pediatric dermatoses pattern at a Brazilian reference center

Abstract Objective: The aim of this study was to identify the pattern of pediatric dermatoses of patients evaluated at a dermatologic clinic of a reference center in Brazil and to compare these results to similar surveys conducted in other countries. Methods: A retrospective study was performed of patients up to 18 years old, evaluated at a dermatologic clinic between January 1, 2017 and December 31, 2017. Variables collected for analysis included age, gender, dermatological diagnosis, multidisciplinary follow-up, hospitalization, and complementary exams. Results: A total of 2330 patients were included for analysis, with a mean age of 9.7 years. 295 patients were diagnosed with more than one skin disease, leading to a total of 2668 diagnoses. Skin diseases were organized into categories and inflammatory dermatoses corresponded to the largest group (31.2%), mostly due to atopic dermatitis (18.3%). The other main categories were: genodermatoses (14.2%), infectious diseases (12.6%), adnexal disorders (12.5%), cysts and neoplasms (10.7%), and vascular disorders (7.0%). Fifty-six patients needed to be admitted to the dermatology ward; 25 of them (44.6%) for management of worsening of the skin disease, mainly atopic dermatitis, psoriasis, and drug reactions. There were 885 biopsies performed in 38.0% of the subjects and 751 patients (32.2%) required multidisciplinary care; most of them had some genodermatoses. Conclusions: Dermatologic disorders are very common in the pediatric age group and differ from those in adults, suffering influence from cultural, ethnic, socioeconomic, and environmental factors. Knowing the magnitude and distribution of these dermatoses is important to better plan healthcare policies.

Validation of the Skindex-17 quality of life assessment instrument for a Brazilian population

Abstract Background: Health-related quality of life assesses how diseases affect the daily life of people; there are several generic instruments for this assessment in dermatology. Skindex was created in 1996; it is a multidimensional instrument, aiming to encompass some psychological and social aspects not yet addressed by other questionnaires. Among its versions (Skindex-29, 16, and 17), Skindex-17 had not been validated in Brazil. Objectives: To validate Skindex-17 for use in Brazilians with dermatological diseases. Methods: This was a methodological, cross-sectional, and prospective study of 217 patients attended at the Dermatology Service Outpatient Clinic, Faculdade de Medicina de Botucatu - Universidade Estadual Paulista (Botucatu, SP, Brazil), from December 2017 to September 2019. The following were evaluated: content validity, filling time, internal consistency, dimensional structure, concurrent validity (DLQI), temporal stability, and responsiveness. Results: The sample consisted of 71% women, mean age (SD) of 45 (16) years; phototypes II−IV accounted for 95% of the cases. Cronbach's alpha coefficients were 0.82 and 0.93 for the symptoms and psychosocial conditions, respectively. A high correlation was observed with the DLQI score: symptoms (rho = 0.69) and psychosocial conditions (rho = 0.75). The instrument's two-dimensional structure was confirmed through confirmatory factor analysis. Temporal stability (ICC > 0.9) and score responsiveness (p ≤ 0.02) were verified. The instrument was shown to be feasible in clinical practice due to the content validation performed by professionals and patients, as well as the low time spent completing it (< 5 min). Study limitations: Single-center study, with patients exclusively from the public healthcare system. Conclusions: Skindex-17 was shown to be a valid and consistent instrument for assessing quality of life among patients with dermatological diseases, in Brazil. Its two-dimensional structure was confirmed.

Esteatocistoma solitario de cuero cabelludo / Solitary steatocystoma of the scalp

El esteatocistoma es un hamartoma quístico de la porción media de las unidades folículo sebáceas que afecta principalmente el ducto sebáceo. Comúnmente se encuentra de manera múltiple y se transmite en forma autosómica dominante; en algunos casos se presenta en un contexto no familiar y en otros puede ser solitario. La primera descripción del esteatocistoma múltiple (EM) muy probablemente corresponde a Jamieson en 1873. La forma solitaria de esteatocistoma fue descrito por primera vez en 1982 por Brownstein y existen pocos casos descritos en la literatura Presentamos un caso clínico de paciente varón joven con tumoración solitaria en cuero cabelludo que fue extirpado cuyo resultado histopatológico fue de esteatocistoma solitario.

Steatocystoma is a cystic hamartoma of the middle portion of the sebaceous follicular units that mainly affects the sebaceous duct. It commonly presents in multiple forms and is transmitted in an autosomal dominant manner; in some cases, it occurs in a non-familial context and in others it may be solitary. The first description of steatocystoma multiplex (MS) is most likely by Jamieson in 1873. The solitary form of steatocystoma was first described in 1982 by Brownstein and there are few cases described in the literature. We present a clinical case of a young male patient with a solitary tumor on the scalp that was excised and whose histopathological result was solitary steatocystoma.

Perfil clínico de pacientes dermatológicos encaminhados para avaliação oftalmológica / Clinical profile of dermatological patients referred to ophthalmological evaluation

RESUMO Objetivo: Analisar o perfil clínico de pacientes em acompanhamento dermatológico encaminhados para avaliação oftalmológica. Métodos: A amostra foi composta de pacientes dermatológicos encaminhados para avaliação oftalmológica, nos anos de 2016 e de 2017. Estudou-se a concomitância de doenças dermatológicas com as afecções oftalmológicas por meio da coleta simultânea do histórico dermatológico (prontuários registrados com dados gerais e diagnóstico) e de dados da consulta oftalmológica após o encaminhamento. Resultados: Foram avaliados pela oftalmologia 224 pacientes, sendo 65% do sexo feminino, 80% caucasianos, com idade variando entre 1 mês e 85 anos. As situações cujo encaminhamento foi mais prevalente foram psoríase, lúpus, vitiligo e rosácea (18,3%, 13,8%, 12,9% e 10,7%, respectivamente). Fototerapia crônica e uso de hidroxicloroquina representaram 35,7% e 22,3% dos pacientes. Casos de neurofibromatose, micose fungoide, líquen plano, neoplasias de pele, atopias, pênfigo e esclerodermia também estiveram presentes. Cegueira legal foi detectada em 6%, e deficiências visuais ligadas a afecções dermatológicas foram verificadas em 16,5% dos casos. As alterações oculares mais prevalentes foram catarata (18,9%), blefarite (15,9%), pterígio (5,3%) e conjuntivite (5,3%). Conclusão: Encontrou-se elevada frequência de alterações oftalmológicas em uma população de pacientes com doenças dermatológicas. Assim, o estudo e a análise de manifestações oculares em pacientes dermatológicos podem auxiliar na detecção precoce e na prevenção de complicações.

ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 years. The conditions more often referred were psoriasis, lupus, vitiligo and rosacea (18.3%, 13.8%, 12.9% and 10.7%, respectively). Chronic phototherapy and use of hydroxychloroquine were observed in 35.7% and 22.3% of patients, respectively. Cases of neurofibromatosis, mycosis fungoides, lichen planus, skin cancer, atopic dermatitis, pemphigus and scleroderma were also reported. Legal blindness was detected in 6% and visual impairment related to skin conditions in 16.5% of patients. The most prevalent ocular changes were cataracts (18.9%), blepharitis (15.9%), pterygium (5.3%) and conjunctivitis (5.3%). Conclusion: A high frequency of ophthalmic changes in a population of dermatological patients was found. In this context, studying and analyzing ocular manifestations in dermatological patients could be useful in early detection and prevention of complications.

Calcinosis cutis congénita tumoral asociada con encefalopatía epiléptica infantil temprana con variante patogénica en el gen FGF12 / Tumorous congenital calcinosis cutis associated with early childhood epileptic encephalopathy with a pathogenic FGF12 gene variant

Resumen Introducción: La calcinosis cutis es el depósito de sales insolubles de calcio en la piel y se clasifica, de acuerdo con su patogénesis, en distrófica, metastásica, idiopática, iatrogénica y calcifilaxis. La calcinosis idiopática se presenta en pacientes sanos y es asintomática; incluye la calcinosis escrotal, la calcinosis nodular de Winer o nódulos calcificados subepidérmicos y la calcinosis tumoral familiar. Esta última es una condición rara que se caracteriza por el depósito de calcio periarticular en pacientes normocalcémicos sin conexión al hueso. Caso clínico: Paciente de sexo masculino de 5 meses de edad, quien al séptimo día de vida fue hospitalizado por ictericia multifactorial, sepsis neonatal tardía y apnea con crisis epilépticas. La evolución fue tórpida, con ingresos hospitalarios por crisis epilépticas de difícil manejo, respuesta parcial a la difenilhidantoína y descontrol electrolítico. Mediante la secuenciación del exoma dirigido se detectó una variante patogénica de sentido equivocado en FGF12 que confirmó el diagnóstico de encefalopatía epiléptica temprana número 47. Además, el paciente presentó dermatosis congénita diseminada a las extremidades inferiores con afección en muslos, asintomática, bilateral y simétrica, constituida por hipopigmentación y fóveas duras a la palpación profunda. La biopsia mostró calcificación distrófica. Conclusiones: Se presenta el caso de un lactante con calcinosis cutis congénita profunda asociada con una variante patogénica en el gen FGF12 y con encefalopatía epiléptica, situación clínica que, a la fecha, no había sido reportada en la literatura.

Abstract Background: Calcinosis cutis is the deposit of insoluble calcium salts in the skin. It is classified according to its pathogenesis in dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis. Idiopathic calcinosis is asymptomatic, occurs in healthy patients, and includes scrotal calcinosis, Winer's nodular calcinosis or subepidermal calcified nodules, and familial tumor calcinosis. The latter is a rare condition characterized by periarticular calcium deposition in normocalcemic patients with no bone connection. Case report: The case of a 5-month-old male patient, who on the seventh day of life was hospitalized for multifactorial jaundice, late neonatal sepsis, and apnea with epileptic seizures is described. His evolution was torpid, with hospital admissions due to epileptic seizures that were difficult to manage with partial response to the use of diphenylhydantoin and electrolyte alterations. By means of exome sequencing directed, a pathogenic variant of wrong direction in FGF12 was detected and the diagnosis of early epileptic encephalopathy number 47 was confirmed. Also, the patient showed disseminated congenital dermatosis to lower extremities affecting thighs, asymptomatic, bilateral and symmetrical, constituted by hypopigmentation and fovea hard to deep palpation. The biopsy showed dystrophic calcification Conclusions: The case of an infant with deep congenital cutis calcinosis associated with a pathogenic variant in the FGF12 gene with epileptic encephalopathy is described.

Pioderma gangrenoso en mamoplastia posbariátrica / Pyoderma gangrenosum in postbariatric mammoplasty

El pioderma gangrenoso es una patología infrecuente, de origen desconocido, caracterizada por la presencia de úlceras cutáneas de carácter necrótico, de aparición recurrente y rápida progresión. Puede manifestarse en cualquier área anatómica a partir de procesos quirúrgicos o traumáticos, que actúan como disparadores de la reacción autoinmune localizada. En pacientes con cirugía reciente, los signos y síntomas de esta patología se asemejan a una infección posoperatoria. El tratamiento se basa en el uso de corticosteroides e inmunosupresores, containdicando la conducta quirúrgica dado que la misma puede exacerbar la enfermedad. Presentamos un caso de pioderma gangrenoso en mastoplastía posbariátrica con inclusión de prótesis.

Pyoderma gangrenosum is a rare pathology of unknown origin, characterized by the presence of necrotic skin ulcers of recurrent appearance and rapid progression. It can emerge in any anatomic area, after surgeries or traumatic procedures which act as triggers of the localized immune reaction. In patients who have undergone recent surgeries, the signs and symptoms from this pathology resemble a post-operative infection. The treatment consist of corticosteroids and/or immunosuppressants. Surgical procedure is contraindicated since it can exacerbate the disease. We present a case of pyoderma gangrenosum in mastopexy with breast implant insertion post bariatric surgery.
