Granuloma eosinofílico cervical en el adolescente: reporte de un caso y revisión de la literatura / Cervical eosinophilic granuloma in adolescents: case report and literature review

INTRODUCCIÓN El granuloma eosinofílico (GE) es una patología infrecuente, sobre todo en adultos, que puede afectar la columna cervical. A pesar de la vasta literatura, esta enfermedad afecta principalmente a la población infantil, y no hay un consenso sobre el manejo en adultos. Con el objetivo de aportar conocimiento respecto a esta patología poco frecuente, se presenta un caso clínico de GE cervical en un paciente de 16 años, a quien se trató de manera conservadora, con buenos resultados y retorno completo a sus actividades. CASO CLÍNICO Un hombre de 16 años, seleccionado de rugby, consultó por dolor cervical axial persistente y nocturno de 6 semanas de evolución, sin trauma evidente. Al examen, destacó dolor a la compresión axial sin compromiso neurológico asociado. Los exámenes de tomografía computarizada (TC) y resonancia magnética (RM) revelaron lesión lítica en el cuerpo de C3 de características agresivas, de presentación monostótica en tomografía por emisión de positrones-tomografía computada (TEP-TC) compatible con tumor primario vertebral. Se decidió realizar biopsia percutánea bajo TC, para definir el diagnóstico y manejo adecuado, la cual fue compatible con células de Langerhans. Al no presentar clínica ni imagenología de inestabilidad ósea evidente o compromiso neurológico, se manejó con tratamiento conservador, inmovilización cervical, analgesia oral, y seguimiento estrecho. A los cuatro meses de evolución, se presentó con una TC con cambios reparativos del cuerpo vertebral y sin dolor, y logró retomar sus actividad habituales. CONCLUSIONES El diagnóstico de GE es infrecuente a esta edad, y se debe plantear entre diagnósticos diferenciales de lesiones líticas agresivas primarias vertebrales. Es necesario el uso de imágenes, y la biopsia vertebral es fundamental para confirmar el diagnóstico. Su manejo va a depender de la sintomatología, del compromiso de estructuras vecinas, y de la estabilidad de la vértebra afectada. El manejo conservador con seguimiento clínico e imagenológico es una opción viable.

INTRODUCTION Eosinophilic granuloma (EG) is a rare, tumor-like lesion, infrequently affecting the cervical spine, particularly in adults. Although vastly described in literature, this pathology mainly affects children, and there is still no consensus on its treatment in older patients. With the goal of contributing to increase the knowledge regarding this infrequent pathology, we present a case of a C3 eosinophilic granuloma in a 16-year-old patient, who was treated conservatively, with good results, including complete return to his previous activities. CLINICAL CASE a 16-year-old male, elite rugby player, presented with a history of persistent neck pain, mainly at night, with no previous trauma. Upon physical examination, he reported neck pain with axial compression of the head, without neurological impairment. Both computed tomography (CT) and magnetic resonance imaging (MRI) scan revealed an aggressive lytic lesion in the C3 vertebral body, a with monostotic presentation on positron emission tomography-computed tomography (PET-CT) compatible with a primary spine tumor. A CT-guided percutaneous biopsy was obtained to establish the diagnosis and provide the proper management. The results were compatible with Langerhans cells. As he presented no symptoms or imaging findings of evident bone instability, as well as no neurological impairment, the patient was treated conservatively, with a cervical brace, oral pain medication and close followup. A CT obtained after four months of treatment showed reparative changes of the C3 vertebral body; at this point, the patient reported no neck pain, so he was able to return to his previous activities. CONCLUSIONS Although an EG is rare at this age, it should be considered in the differential diagnosis of primary vertebral aggressive lytic lesions. Imaging and a vertebral biopsy are paramount to confirm the diagnosis. The treatment modality depends on the symptoms, the involvement of adjacent structures, and the stability of the affected vertebra. Conservative management including clinical and imaging followup is a viable option.

Spontaneous remission of eosinophilic granuloma of the maxilla after incisional biopsy: a case report.

BACKGROUND: Langerhans cell histiocytosis (LCH), previously known as Histiocytosis X, is an infrequent disease that congregates a wide spectrum of clinical presentations with variable systemic involvement. Unification of these diseases under only one category is based on the almost identical histopathologic features of the lesions, but the etiology and proper approach for each presentation remains controversial. The localized alternative of Langerhans cell histiocytosis (LLCH), known as Eosinophilic Granuloma (EG) of bone, is the predominant clinical presentation of LCH. The maxilla is involved in 1 % of the head and neck region cases, representing an uncommon condition in this area. CASE PRESENTATION: In this clinical case report, it is described a case of a 16-year-old male patient with an asymptomatic osteolytic lesion at first upper left molar apical level, a finding detected on control radiographic images was reported as "Monostotic Eosinophilic granuloma of the maxillary bone", which was later confirmed through an incisional biopsy. A surgical excision was initially planned, but finally it was not performed due to a spontaneous healing of the lesion after the incisional biopsy. CONCLUSIONS: The presented case supports a conservative approach in the management of solitary EG of maxillary and mandibular bone lesions and even supports an expectant attitude in the course of treatment given the possibility of a spontaneous regression after the biopsy, especially in small lesions.

Granuloma eosinofílico da coluna vertebral cervical em criança / Eosinophilic granuloma of the cervical spine in children

Granuloma eosinofílico (GE) refere-se à forma benigna e mais frequente de histiocitose de células de Langerhans. Trata-se de uma doença que acomete principalmente crianças e adolescentes, sendo rara a sua ocorrência em adultos. Constitui a forma localizada de proliferação de histiócitos em crânio e ossos longos. O acometimento vertebral é incomum, sendo a localização cervical a menos descrita. Neste artigo, é descrito um caso de uma criança de 7 anos de idade com GE na coluna vertebral cervical com compressão medular. A criança evoluiu com regressão dos sintomas após tratamento conservador, tendo permanecido assintomática ao longo de seguimento de dois anos.

Eosinophilic granuloma (EG) is a benign and more frequent form of Langerhans cell histiocytosis. Children and adolescent are mainly affected, being rare in adults. There is local proliferation of histiocytes in skull and long bones. Vertebral involvement is uncommon, especially at the cervical local. In this paper, we describe a case of a 7 years old child with EG in the cervical spine with spinal cord compression. The patient presented with regression of symptoms after conservative treatment and remained asymptomatic at the two years follow-up.

Granuloma eosinofílico primário do pulmão: registros clássicos / Primary eosinophilic granuloma of the lung: classical records

Foram analisados, retrospectivamente, cinco casos de granuloma eosinofílico primário do pulmão (GEPP) identificados durante admissão no Hospital Universitário Lauro Wanderley da Universidade Federal da Paraíba (HULW/UFPB), no interregno de 1982 a 1998, admitidos com história diagnóstica de fibrose intersticial difusa (FID). Foram revisados os seguintes aspectos: formas de apresentação clínica e epidemiológica, presunção diagnóstica na admissão, doenças concomitantes e evolução terapêutica. A presunção clínica do diagnóstico foi confirmada mediante a citometria com níveis elevados de CD1 no lavado broncoalveolar (LBA). A biópsia pulmonar aberta foi indicada pelos sintomas persistentes em acompanhamentos ambulatoriais sem melhora clínica. O relatório anatomopatológicodemonstrou histiocitose de células de Langhans. A terapia à base de corticosteróides não apresentou boa eficácia, uma vez que, observando a evolução clínica dos casos apresentados, ocorreram dois óbitos e os demais não tiveram uma melhora significativa da enfermidade de base, porém existiu um prejuízo nessa avaliação, em virtude do não-abandono do vício tabágico. Enfatiza-se a fisiopatogenia e a importância dessa enfermidade, apesar de rara e pouco conhecida, como causa de FID, ilustrando um dos casos que se reveloubastante exuberante no diagnóstico de GEPP.

We studied retrospectively five cases of eosinophylic granuloma of the lung identified during admission at HULW/UFPB from 1982 to 1998. They were admitted with diagnostical history of difuse intersticial fibrosis. The following aspects were reviewed: clinical and epidemilogical presentation, diagnostic presumption at admission, concomitant diseases and evolution. The diagnostic was confirmed with bronchoalveolar lavage (BAL) and lung biopsy. The anatomicopathologic exams report histiocytosis of Langhans'cells. The clinical course was variable. There are no accepted successful treatment, although three patients responded poorly to corticosteroids and twodied, in spite of all effort in the treatment with corticosteroids too.

Histiocitosis X pulmonar primaria (granuloma eosinofílico pulmonar)

La histiocitosis X pulmonar primaria es una patología infrecuente que afecta predominantemente a personas entre los 20 y los 40 años, usualmente con historia de tabaquismo. Presentamos un grupo de tres pacientes con esta entidad que se estudiaron en el Hospital Santa Clara en los últimos 20 años. Los síntomas más frecuentes fueron tos con expectoración mucosa y disnea. En todos se documentó historia de tabaquismo. La radiografía de tórax mostró infiltrado intersticial reticulonodular difuso, con volumen pulmonar normal y signos de hipertensión pulmonar precapilar. Todos se presentaron con hipoxemia severa y cor pulmonale. La histopatología confirmó el diagnóstico de histiocitosis X pulmonar primaria.

Eosinophilic granuloma of the cervical and thoracic spine in a child

A case of eosinophilic granuloma affecting a cervical vertebra, thoracic vertebra and pelvis in a child is reported. We present this case because multifocal eosinophilic granuloma lesions of the spine are rare and can present as this case did with both diagnostic and therapeutic problems. Preoperative diagnosis may be made by X-ray, isotope bone scan and needle biopsy, avoiding unnecessary surgical intervention (AU)

Granuloma eosinófilo ósseo: estudo baseado em 19 casos / Eosinophilic granuloma of bone: study of 19 cases

Os autores estudam clínica e radiograficamente 19 casos comprovados por biópsia de granuloma eosinófilo ósseo. Näo houve nenhum caso de transiçäo para a doença de Hand-Schuller-Christian ou a de Letter-Siwe. Os achados radiográficos näo säo característicos, sendo que as lesöes podem ser confundidas com neoplasias malignas. A biopsia é imperativa para o diagnóstico definitivo. Todas as lesöes analisadas regrediram completamente, independente do tratamento instituído. Nas lesöes de fácil acesso cirúrgico, a curetagem simples pôde ser utilizada, com bons resultados. Nas lesöes de difícil abordagem cirúrgica, a administraçäo de corticoterapia oral teve igualmente bom resultado

[Eosinophilic granuloma of the cervical spine with atypical neurological, cerebrospinal fluid and radiological manifestations]. / Granuloma eosinofilo da coluna cervical com manifestacão neurologica, liquorica eradiologica atipica

A case of eosinophilic granuloma of the cervical spine in a ten year-old white boy is reported. The patient complained of posterior cervical pain at the level of C5-C6 and right hemiparesis that progressed to mixed tetraparesis (lower motor neuron in upper limbs and upper motor neuron in lower limbs). Examination of the cerebrospinal fluid (CSF) disclosed an inflammatory reaction; radiologic studies of the cervical spine showed an irregular aspect with demineralization at the base of spinous process of C6. The patient was treatet intermitently with corticosteriods (prednisone); there was an improvement of neurologic symptoms and the examination of the CSF was normal within a few days, each time he took the drug. Neurologic symptons and abnormalities of the CSF recurred after discontinuation of corticotherapy. Examination of a fragment of the spinous process and neighboring tissues of C6, taken by biopsy, disclosed eosinophilic granuloma. Radiotherapy was then indicated, plus corticosteroids. There was remission of all neurologic symptoms and signs. The unusual features of the case are discussed in relation to others reported in the literature.
