RESUMO
This study evaluates the clinical accuracy of OpenAI's ChatGPT in pediatric dermatology by comparing its responses on multiple-choice and case-based questions to those of pediatric dermatologists. ChatGPT's versions 3.5 and 4.0 were tested against questions from the American Board of Dermatology and the "Photoquiz" section of Pediatric Dermatology. Results show that human pediatric dermatology clinicians generally outperformed both ChatGPT iterations, though ChatGPT-4.0 demonstrated comparable performance in some areas. The study highlights the potential of AI tools in aiding clinicians with medical knowledge and decision-making, while also emphasizing the need for continual advancements and clinician oversight in using such technologies.
RESUMO
Molluscum contagiosum (MC) is a common viral infection in children, immunocompromised, and sexually active adults. Its usual clinical presentation is 2-5 mm, whitish or skin-colored papules, with a shiny surface and central umbilication, generally clustered and randomly distributed over the skin surface. Dermoscopy reveals yellowish-white polylobulated structures with peripheral telangiectasia. Diagnosis is usually clinical supported by dermoscopy. However, in some cases, inflammatory manifestations can be associated with this infection and can mimic other dermatological conditions, making the diagnosis difficult and leading to unnecessary treatments. The objective of this article is to describe the main skin reactions associated with MC infection in order to provide a diagnostic and initial management tool for clinicians dealing with these conditions. Reported manifestations include the BOTE sign, perilesional eczema, Gianotti-Crosti syndrome-like reaction, ID reaction, erythema annulare centrifugum, erythema multiforme, folliculitis, white halo, and atypical manifestations (giant, disseminated, necrotic, polypoidal, and nodular lesions, pseudocysts, abscesses). In pediatric patients with the clinical manifestations described above, infection by molluscum contagiosum pox virus should be considered among the differential diagnoses, and referral to a dermatologist should be made in selected cases.

Trichophyton violaceum es un dermatofito antropofílico endémico en África, Europa, Centroamérica y China. El incremento de los fenómenos de movilidad humana ha contribuido a su aparición en áreas no endémicas. Su principal manifestación clínica es la tinea capitis, seguida por la tinea corporis. En la población pediátrica afecta con mayor frecuencia el cuero cabelludo; y en adultos, la piel glabra. Presentamos el primer caso en Chile de tinea causada por T violaceum. Correspondió a una mujer chilena de 21 años que presentó placas faciales de un mes de evolución después de un viaje a Tanzania, África, sin respuesta a tratamientos médicos previos. Se sospechó una dermatofitosis alóctona y mediante cultivos especiales, se identificó una colonia de crecimiento lento, coloración violeta-negruzca, superficie cerosa y rugosa, con vellosidades aterciopeladas; compatible con T violaceum. Se confirmó mediante secuenciación de ADN ribosomal amplificando la región ITS. Se trató con terbinafina oral con respuesta clínica completa.
Trichophyton violaceum is an anthropophilic dermatophyte endemic in Africa, Europe, Central America and China. The increase in human mobility has recently contributed to the appearance in non-endemic areas. The main clinical manifestation is tinea capitis followed by tinea corporis. We present the first case in Chile of tinea caused by T violaceum. The case was a 21 year-old Chilean woman who presented asymptomatic facial plaques one month after arriving from Tanzania, Africa, with no clinical response to previous medical treatments. An allochthonous dermatophytosis was suspected and with special cultures, a slow-growing colony was identified with a violet-blackish color, waxy and rough surface, and velvety villi; all characteristics of T violaceum. The diagnosis was confirmed by ribosomal DNA sequencing amplifying the ITS region. She was treated with oral terbinafine obtaining a complete clinical response.
