ABSTRACT
INTRODUCTION: Flagellated dermatitis is an infrequent pathology, with characteristic skin lesions, which is developed due to the use of bleomycin. Clinically it occurs as erythematous or hyperpigmented maculae of linear disposition with flagellar pattern, in trunk and/or upper extremities. It presents self-limited evolution, therefore, its treatment varies from expectant management to the use of topical or oral corticosteroids. OBJECTIVE: Presentation of a clinical case of flagellated dermatitis secondary to bleomycin in a pediatric patient with history of central nervous system neoplasia. CLINICAL CASE: 8 years, schoolchild, female, with a history of primary intracranial mixed germ cell tumor (sellar and suprasellar) and secondary panhypopituitarism. She receives chemotherapeutic treatment according to the PEB protocol, with use of IV bleomycin during three days. After two days, intermittent pruritus begins, associated with erythematous and pigmented maculae of linear distribution, followed by a flagellated pattern, with isolated signs of excoriation, in the abdominal region and upper back. Topical treatment with mild potency corticosteroids is indicated for ten days, with a satisfactory clinical response. CONCLUSIONS: There should be a high diagnostic suspi cion in pediatric patients with a history of prior administration of the drug and the appearance of characteristic skin lesions, which will allow adequate behavior regarding its management and the continuity of chemotherapy.

INTRODUCCIÓN: La Dermatitis Flagelada es una patología infrecuente, con lesiones cutáneas características, que se desarrolla por el uso de Bleomicina. Clínicamente se presenta como maculas eritematosas o hiperpigmentadas de disposición lineal con patrón flagelar, en tronco y/o extremidades superiores. Presenta evolución autolimitada por lo que su tratamiento varía desde conducta expectante hasta uso de corticoides tópicos u orales. OBJETIVO: Presentación de un caso clínico de Dermatitis flagelada secundaria a Bleomicina en paciente pediátrico con antecedentes de neoplasia de sistema nervioso central. CASO CLÍNICO: Escolar de 8 años, sexo femenino, con antecedentes de tumor prima rio de células germinales mixto intracraneal (selar y supraselar) y panhipopituitarismo secundario. Recibe tratamiento quimioterapéutico según protocolo PEB, con uso de Bleomicina EV por 3 días. A los 2 días posteriores, inicia prurito intermitente, asociado a máculas eritematosas y pigmentadas de distribución lineal, siguiendo patrón flagelado, con aislados signos de excoriación, en región abdominal y dorso alto. Se indica tratamiento tópico con corticoides de moderada potencia por 10 días, con respuesta clínica satisfactoria. CONCLUSIONES: Se debe tener una alta sospecha diagnóstica en pacientes pediátricos con historia de administración previa del fármaco y aparición de lesiones cutáneas características, lo que permitirá una conducta adecuada respecto a su manejo y a la continuidad de la quimioterapia.

La Urticaria Pigmentosa es el tipo más frecuente de mastocitosis cutánea (MC) de inicio en la edad pediátrica, representando el 75 por ciento de las MC. Se presenta con máculas y/o pápulas de color amarillo a café-rojizo, usualmente con signo de Darier positivo y prurito. El 88 por ciento presenta compromiso de tronco. En este artículo compartimos el caso de Urticaria Pigmentosa de presentación atípica: predominio de lesiones en cara y sin compromiso de tronco.(AU)
Urticaria Pigmentosa is the most common form of cutaneous mastocytosis (CM) starting in childhood and accounts for 75 percent of all the CM cases. It presents with yellow to brown-reddish macules or papules, usually with positive Darier sign and itching. Trunk involvement is present in 88 percent of patients. In this article we describe a case of Urticaria Pigmentosa with an atypical presentation: facial predominance without trunk involvement. (AU)

Los tumores y pseudotumores ungueales representan un desafío diagnóstico, principalmente, dada la compleja anatomía de la uña y la apariencia clínica similar de estas lesiones. La exostosis subungueal es una entidad de baja frecuencia que debe considerarse en el diagnóstico de las masas subungueales. No es un tumor verdadero, sino crecimiento anormal de hueso o una calcificación de tejido cartilaginoso. En el siguiente artículo, se comunica el caso de una exostosis subungueal y realizamos una breve discusión, enfatizando los diagnósticos diferenciales, principalmente el melanoma subungueal, que debe sospecharse siempre y derivarse en forma precoz.(AU)
Nail tumors and pseudotumors represent a diagnostic challenge, mainly due to the complex anatomy of the nail and similar clinical appearance of these lesions. Subungual exostosis is an entity of low frequency, which should be considered in the differential diagnoses of subungual masses. It is not a true tumor, but an overgrowth of bone or cartilage tissue calcification. In the following article, we report the case of a subungual exostosis and perform a brief discussion, emphasizing the differential diagnoses, including the subungual melanoma, which should always be suspected and referred in a timely manner.(AU)

La úlcera genital aguda (UGA) o úlcera de Lipschütz constituye una infrecuente entidad clínica caracterizada por la aparición de úlceras genitales en niñas y adolescentes que no han iniciado su actividad sexual. El cuadro es de inicio agudo, con formación de úlceras dolorosas habitualmente precedidas en su aparición por manifestaciones sistémicas tales como fiebre, cefalea, astenia, adinamia, mialgias y adenopatías inguinales, y donde el estudio microbiológico de la lesión descarta un posible origen infeccioso. A pesar de presentar un cuadro clínico característico, esta enfermedad constituye una entidad poco conocida y por tanto subdiagnosticada, motivo por el cual presentamos el caso de una paciente de 10 años con diagnóstico de UGA realizado en el Departamento de Dermatología de la Pontificia Universidad Católica de Chile.
Acute genital ulcer (AGU) or Lipschütz ulcer is a rare clinical entity characterized by the appearance of genital ulcers in children and adolescents who have not initiated sexual activity. The picture is of acute onset, with formation of painful ulcers on their occurrence usually preceded by systemic manifestations such as fever, headache, fatigue, weakness, muscle pain and inguinal lymphadenopathy, and where the microbiological study of injury rule out a possible infectious origin. Despite presenting a characteristic clinical picture, this disease is a little known entity and under diagnosed, we present the case of a 10 years old girl diagnosed with UGA conducted at the Department of Dermatology, Catholic University of Chile.

El hemangioma es el tumor vascular benigno más frecuente de la infancia y su asociación con otras malformaciones es rara. Se ha descrito recientemente asociado al síndrome de PHACES, que corresponde a una alteración del desarrollo en la gestación precoz. Este síndrome se caracteriza por la presencia de un gran Hemangioma facial (H) asociado a otras anomalías como: malformaciones cerebrales de la fosa Posterior (P), alteraciones de las arterias cervicocraneales y Coartación de la aorta (C), defectos oculares (E) y esternón hendido y/o rafe supraumbilical (S). Afecta de preferencia al sexo femenino y la mayoría tiene sólo una manifestación extracutánea.
The hemangioma is the most common benign vascular tumor in childhood and is rarely related to other systemic malformations. It has been recently described in association with PHACES syndrome, which is an alteration in gestational development. This syndrome presents a large facial Hemangioma (H), with other anomalies like: Posterior fossa brain malformation (P), cervicocraneal arterial anomalies and coarctation of the aorta (C), ophthalmologic disorders (E), and midline abdominal and sternal defects (S). Females are more frequently affected and there is usually only one extracutaneous manifestation.
