RESUMO
Introducción: La sarcoidosis es una enfermedad granulomatosa crónica y multisistémica, de etiología desconocida. En pacientes pediátricos tiene dos formas de presentación: el síndrome clásico con afección del pulmón y ganglios linfáticos, y la sarcoidosis de inicio temprano (SIT), caracterizada por la tríada: uveítis, artritis y erupción cutánea papular. Se han comunicado varios casos de SIT que inicialmente fueron diagnosticados como artritis idiopática juvenil (AIJ), su principal diagnóstico diferencial. Después de la detección de dos casos de SIT en pacientes con diagnóstico previo de AIJ seronegativa, decidimos rastrear nuevos casos dentro de este grupo de pacientes en nuestra institución, por las posibles repercusiones sistémicas de la sarcoidosis.Material y método: Estudio observacional, descriptivo y transversal realizado en el Instituto Nacional de Pediatría, en el que se rastrearon posibles casos de SIT entre 597 pacientes con diagnóstico inicial de AIJ. Resultados: Se detectó un posible caso de SIT entre los pacientes investigados, pero no se confirmó la enfermedad por datos histológicos.Discusión: Recomendamos sospechar el diagnóstico de SIT en los pacientes menores de cuatro años con un síndrome artrítico. Además, consideramos importante el seguimiento de los pacientes con AIJ seronegativa que hayan iniciado su enfermedad antes de los cuatro años de edad por la posibilidad de que realmente sea una SIT, considerando que puede derivar en complicaciones sistémicas que ponen en peligro la vida del paciente.
Introduction: Sarcoidosis is a multisystemic, chronic and granulomatous disease of unknown etiology. In pediatric patients it has two forms of presentation: the classic syndrome with pulmonary involvement and lymph node disease, and early onset sarcoidosis (EOS), characterized by a triad of uveitis, arthritis and papular skin rash. Several cases of EOShave been initially misdiagnosed as juvenile idiopathic arthritis (JIA), its main differential diagnosis. After having detected two cases of EOS previously diagnosed as JIA we decided to seek for new cases of EOS among patients with the diagnosis of seronegative JIA.Material and method: An observational, descriptive and cross-sectional study was performed on 570 patients previously diagnosed with JIA looking for possible cases of EOS at the National Institute of Pediatrics.Results: A possible case of EOS was detected in the investigated patients, but the disease was not confirmed by histological data on skin biopsy.Discussion: We suggest EOS should be considered in patients under four years of age when evaluated for idiopathic arthritis. Patients diagnosed with seronegative JIA having initiated their disease before the age of four years should be carefully follow-up due to the possibility of a misdiagnosis, since EOS can be a life-threatening disease.

The common manifestations of atopic dermatitis (AD) appear sequentially with involvement of the cheeks in infancy, flexural extremities in childhood, and hands in adulthood. Although less common clinical manifestations are well described, they have not been the subject of epidemiologic studies to describe their prevalence in specific age groups. This observational, cross-sectional, comparative study included 131 children younger than 18 of both sexes with AD who attended the clinics of the Dermatology Department of the National Institute of Pediatrics in Mexico City. Patients were examined to determine the presence of infrequent clinical manifestations of AD during infancy, preschool and school age, and adolescence and stratified according to sex, age, and number of clinical signs. A chi-square test was used to detect differences according to age and sex. Logistic regression analysis was also performed. The main findings according to age were genital dermatitis and papular-lichenoid dermatitis variant in infants; atopic feet, prurigo-like, nummular pattern, and erythroderma in preschool and school-aged children; and eyelid eczema and nipple dermatitis in adolescents. The risk of development of nipple dermatitis and eyelid eczema increased with age, and the development of genital dermatitis decreased with age. The knowledge of the prevalence of less common clinical manifestations of AD according to age in different populations might be helpful in diagnosing incipient cases of AD.

Congenital cutaneous angioleiomyoma is an extremely rare benign smooth muscle tumor. We present a case of a firm, painful subcutaneous mass noticed at birth on the left leg that on surgical excision proved to be an angioleiomyoma. Prognosis is good, and recurrences are uncommon. To our knowledge, this is the second report of a congenital angioleiomyoma.

Chronic mucocutaneous candidiasis is a primary immunodeficiency characterized by persistent or recurrent candidal infections of the skin, nails and/or mucosal tissues. CMC can be associated with endocrinopathies such as hypoparathyroidism, Addison's disease, hypothyroidism, type 1 diabetes mellitus or hypogonadism. Other associated conditions include autoimmune diseases such as autoimmune gastritis and autoimmune hepatitis. We report a patient with CMC and decreased T cell, natural killer cells without other associated condition.
