Infantile systemic juvenile xanthogranuloma case with massive liver infiltration

Infantile systemic juvenile xanthogranuloma (ISJXG) is an uncommon form of juvenile xanthogranuloma, a non-Langerhans cell proliferation of infancy and early childhood. In a small percentage of patients, the visceral involvement­most commonly to the central nervous system, liver, spleen, or lungs­may be associated with severe morbidity, and eventually fatal outcome. Here we describe the clinical and pathological findings of a 28-day-old girl with ISJXG who died with respiratory distress syndrome. She had few cutaneous lesions but massive liver and spleen infiltration; other affected organs were multiple lymph nodes, thoracic parasympathetic nodule, pleura, pancreas, and kidneys. Additional findings were mild pulmonary hypoplasia and bacteremia. Immunohistochemistry on fixed tissues is the standard for diagnosis. Immunophenotype cells express CD14, CD68, CD163, Factor XIIIa, Stabilin-1, and fascin; S100 was positive in less than 20% of the cases; CD1a and langerin were negative. No consistent cytogenetic or molecular genetic defect has been identified. This case demonstrates that the autopsy is a handy tool, because hepatic infiltration, which was not considered clinically, determined a restrictive respiratory impairment. In our opinion, this was the direct cause of death.

Juvenile xantogranuloma with íris involvement / Xantogranuloma juvenil com acometimento iriano

Abstract Herein we report a case of juvenile xantogranuloma, an inflammatory disease more commonly diagnosed during childhood and is characterized by cutaneous and ocular manifestations. Iris is the main target, presenting as local or diffuse yellowish lesions. Iris involvement may precipitate not only glaucoma but also amblyopia. Treatment is based on corticosteroids therapy, either local or systemic aiming disease control.

Resumo É relatado um caso raro de xantogranuloma juvenil, doença de natureza inflamatória diagnosticada mais frequentemente na infância, com manifestações cutâneas e oculares. A íris é o principal sítio extracutâneo da doença, apresentando-se como lesão amarelada, difusa ou localizada. O acometimento iriano pode acarretar surgimento de glaucoma, além de ambliopia. O manejo clínico da lesão ocular no presente caso foi baseado no necessidade no uso contínuo de corticoide tópico e sistêmico para estabilização da doença.

Histiocitosis eruptiva generalizada-xantogranuloma juvenil: espectro clínico en un paciente pediátrico / Generalized eruptive histiocytosis-Juvenile xanthogranuloma: clinical spectrum in a pediatric patient

La histiocitosis eruptiva generalizada, conjuntamente con el xantogranuloma juvenil, constituyen desórdenes histiocíticos de origen dendrítico (también denominados histiocitosis no Langerhans), que comparten características clínico-patológicas e inmunohistoquímicas. Presentamos a una paciente de 3 años de edad con lesiones en la piel clínicamente compatibles con histiocitosis eruptiva generalizada y confirmadas mediante histología e inmunohistoquímica. Luego presentó compromiso en el sistema nervioso central, por lo que fue intervenida quirúrgicamente. En la histopatología de esta lesión, se encontraron células de Touton, compatibles con el diagnóstico de xantogranuloma juvenil. Este caso clínico demuestra la necesidad de considerar estas enfermedades como espectro de una misma entidad.

Both, generalized eruptive histiocytosis and juvenile xanthogranuloma are dendritic histiocytic disorders (also known as non-Langerhans cells histiocytosis) that share clinicopathological and immunohistiochemical characteristics. We present a 3-year-old female patient with skin lesions that were clinically compatible with generalized eruptive histiocytosis, confirmed by histopathological and immunohistochemical studies. During her development the disorder compromised the central nervous system, and surgical intervention of one symptomatic lesion was needed. The histopathological exam of the central nervous system lesion showed Touton cells, compatible with a diagnosis of juvenile xanthogranuloma. This case demonstrates the need to consider these diseases as a spectrum of the same entity.

Xantogranuloma juvenil diseminado con buftalmos, hipema, aumento de presión ocular, en una niña de 4 meses de edad / Disseminated juvenile xanthogranuloma with buphthalmos, hyphema, high intraocular pressure, on a tour month-old infant girl

El xantogranuloma juvenil es un tumor benigno secundario a una proliferación de células histiocíticas que se presenta en lactantes y niños; su aparición en adultos es ocasional. Se inicia en forma repentina por la aparición de lesiones cutáneas papulonodulares rojizo anaranjadas, redondeadas, de 2 a 6 mm, que se localizan preferentemente en cara y parte superior del cuerpo. Se resuelve en forma espontánea en un período variable. Las lesiones suelen estar limitadas a la piel pero pueden tener otra localización. La ocular es una de las que puede presentar severas complicaciones que incluyen glaucoma, hipema, proptosis y amaurosis como en la paciente de 4 meses que presentamos.

Juvenile xantogranuloma (JXG) is a benign tumor due to the prolifera-tion of histiocytic cells, which appears in infants and children and occasionanlly in adults. It has a sudden onset which consists of erythematous or yellowish, papulonodular, slightly raised lesions, with a diameter varying from 2 to 6 mm. It is usually located on the face and upper part of the body, and has a spontaneous remission in a variable period of time. Although lesions are usually limited to the skin, other organs may be involved. Ocular involvement may lead to severe complications including glaucoma, hyphema, proptosis and blindness, as the four months-old patient we report.

Histiocitose cutânea não-Langerhans como causa de diabetes insípido central / Cutaneous non-Langerhans cells histiocytoses as cause of central diabetes inspidus

As histiocitoses são doenças raras, resultantes de alterações na linhagem monocítica-histiocítica, com manifestações clínicas diversas. Entre as síndromes cutâneas de células não-Langerhans, o xantoma disseminado é a única entidade desse grupo classicamente associada ao diabetes insípido central (DIC). O caso clínico relatado refere-se a um paciente de 30 anos de idade que, dois anos após o diagnóstico de DIC, evoluiu com lesões cutâneas papulosas, eritêmato-acastanhadas, difusas, discretas e não confluentes. Os achados histológicos, imuno-histoquímicos e a microscopia eletrônica mostraram resultados compatíveis com a histiocitose de células não-Langerhans e sugestivos do xantogranuloma juvenil. A avaliação endócrino-metabólica não mostrou alterações durante o seguimento por 10 anos, com exceção do DIC. A ressonância magnética da hipófise demonstrou ausência do sinal hiperintenso (mancha brilhante) correspondente à neuro-hipófise. As radiografias e a cintilografia dos ossos não mostraram lesões osteolíticas. Este caso desperta a atenção para a importância do exame da pele nos casos de DIC e de sua associação com a histiocitose de células não-Langerhans de maneira mais ampla, e não restrita aos casos de xantoma disseminado.

The histiocytoses are rare diseases caused by alterations in the monocyte-histiocytic series with several clinical findings. Among the cutaneous syndromes of non-Langerhans cells, xanthoma disseminatum is the only disease of this group that has been classically associated to the central diabetes insipidus (CDI). The case reported describes a 30-year-old man that two years after presenting with CDI developed non confluent disseminated cutaneous brown papular lesions throughout the body. The histopathology, immunohistochemistry, and electronic microscopy were compatible with the diagnosis of non-Langerhans histiocytoses, suggesting the diagnosis of juvenile xanthogranuloma. The endocrine-metabolic evaluation did not show other alterations besides CDI in a 10-year follow up. The magnetic resonance of hypophysis showed absence of the pituitary hyperintense sign (bright spot). The radiologic and scinthigraphic evaluation of the bones did not show the presence of osteolytic lesions. This case prints out the importance of skin examination in cases of CDI and its association with cutaneous non-Langerhans histiocytoses in a broader spectrum, rather then restricted to the cases of xanthoma disseminatum.

Bilateral spontaneous hyphema in juvenile xanthogranuloma.

This report describes a rare occurrence of bilateral, spontaneous, nontraumatic hyphema in a 6 weeks old infant, associated with a small, multiple skin lesions. The diagnosis of juvenile xanthogranuloma was confirmed by histopathological examination of the cutaneous lesions. The hyphaema cleared gradually in 2 weeks time with conservative management.

Xantogranuloma nodular: variedad multinodular / Nodular xanthogranuloma: multinodular variety

Se presenta el caso de un niño de quince meses de edad con lesiones nodulares múltiples asintomáticas en cuero cabelludo, que fueron aumentando en número desde los seis meses de vida con crecimiento acelerado en los últimos tres meses, resultando lesiones de más de 10 mm de diaámetro, hecho que motivó la consulta. En el resto del examen físico se hallaron también tres máculas café con leche en el tronco, de aproximadamente 5 mm de diámetro, con antecedentes familiares de las mismas. Los diferentes diagnósticos diferenciales de esta patología, su variedad macronodular y su posible asociación con neurofibromatosis motivaron la presente comunicación

Neurofibromatosis: con xantogranulomatosis cutánea juvenil y leucemia mielomonocítica crónica juvenil / Neurofibromatosis: with juvenile cutaneous xanthogranulomatosis and juvenile chronic myelomonicytic leukemia

El objetivo del presente reporte es la descripción de un paciente de la Clínica Pediátrica "B" del hospital "Pereira Rossell", portador de la asociación: Neurofibromatosis de Von Recklinghausen (NF); Xantogranulomatosis Cutánea Juvenil (XCJ) y Leucemia Mielomonocítica Crónica Juvenil (LMMCJ)

Asociación de xantogranuloma juvenil y neurofibromatosis de Von Recklinghausen: seguimiento de un caso durante 21 años / Association of juvenile, xanthogranuloma and Von Recklinghausen's neurofibromatosis: follow-up of a case during 21 years

Presentamos un paciente que a los seis meses desarrolló lesiones de xantogranuloma juvenil que involucionaron en tres años. A los cinco años se diagnosticó una neurofibromatosis de von Recklinghausen en base a tumores diseminados (neurofibromas), máculas café con leche y compromiso óseo. Ambas patologías se manifestaron en dos etapas diferentes de la vida sin superposición de lesiones activas. Sugerimos que los infantes con xantogranuloma juvenil, deben ser controlados por años buscando la presencia de neurofibromatosis. Así se podrá lograr una exacta evidencia de la asociación
