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.

Multifocal eosinophilic granuloma of the jaws with long-term follow-up: a case report / 华西口腔医学杂志

Eosinophilic granuloma, a rare disease, has various clinical manifestations and no specific X-rays features and is thus easily misdiagnosed. This paper reports a case of multifocal eosinophilic granuloma of jaw with long-term follow-up. The patient initially presented with periodontal tissue destruction.The diagnosis, treatment and prognosis of multifocal eosinophilic granuloma of jaw were discussed in combination with the literature to alert this disease in clinical practice.

Langerhans' cell histiocytosis with neurological injuries diagnosed from a single cutaneous lesion

Abstract: Histiocytoses are rare diseases caused by the proliferation of histiocytes. The pathogenesis remains unknown and the highest incidence occurs in pediatric patients. The clinical presentations can be varied, in multiple organs and systems, and the skin lesions are not always present. Evolution is unpredictable and treatment depends on the extent and severity of the disease. It is described the case of a patient with various neurological symptoms, extensively investigated, who had its was diagnosed with histiocytosis from a single skin lesion. This report highlights the importance of Dermatology in assisting the investigation of difficult cases in medical practice.

Honey comb lung

Honey comb lung is a radiological term indicating the presence of fairly thick walled cysts, usually 0.5-2 cm in diameter, which don,t fill with contrast material at bronchography. These changes may be diffuse or localized. The cysts probably represent dilated and thickened terminal and respiratory bronchioles. The main causes of diffuse honey combing are idiopathic pulmonary fibrosis; rheumatoid lung; histiocytosis X; tuberous sclerosis and neurofibromatosis
