RÉSUMÉ

Erdheim-Chester disease is a rare non-Langerhans cell histiocytosis (LCH) that affects different body systems. It was recently recognized as a neoplastic disorder after identifying an activating mutation of the MAPK pathway. Neurological presentations of ECD are rare. We present a case of a 35-year-old male who presented to the emergency department with neck pain, headache and vomiting for 2 months; MRI showed multiple heterogeneous intracranial masses. Neurosurgery performed a suboccipital craniotomy, partially resected the cerebellar mass, and placed a parietal to frontal shunt catheter. Biopsy results from the cerebellar mass demonstrated cerebellar tissue involved by a diffuse proliferation of foamy histiocytes and spindle cells admixed with prominent lymphoplasmacytic infiltrate and positive for CD68, CD163, Factor XIIIa and Fascin. PET scan showed hypermetabolic uptake within the medullary portions of the diffuse abnormal lesions of the distal femurs, tibias, and fibulas, and cardiac MRI was nonsignificant. The patient was started on vemurafenib and continued to show improvement in a 3-month outpatient follow-up.

RÉSUMÉ

Abstract Erdheim-Chester Disease is a rare entity, classified as an inflammatory myeloid neoplasm, with an unknown incidence, occurring preferentially in men after 50 years of age. Classically, it has a multisystemic presentation, with the skeletal system being the most frequently affected (90% of the patients), followed by genitourinary involvement in 60% of cases and central nervous system in the pituitary and diabetes insipidus in 25% of the cases. Cardiovascular manifestations are present in more than half of the patients, with aortic infiltration and atrial pseudotumor being the most common forms.


Resumo A doença de Erdheim-Chester é uma entidade rara classificada como neoplasia mielóide inflamatória, com incidência desconhecida que ocorre preferencialmente em homens após os 50 anos de idade. Classicamente apresenta-se de forma multissistêmica, sendo sistema esquelético o mais frequentemente comprometido (90% dos pacientes), seguido do sistema geniturinário em 60% dos casos e sistema nervoso central em hipófise e diabetes insipidus em 25% dos casos. As manifestações cardiovasculares estão presentes em mais da metade dos pacientes, sendo a infiltração da aorta e o pseudotumor atrial as formas mais encontradas.

RÉSUMÉ

We report a 76-year-old male who was admitted due to progressive congestive heart failure lasting several months. An echocardiogram showed a large pericardial effusion with early signs of pericardial tamponade and an irregular surface suggestive of cancer infiltration. The patient was operated, creating a pericardial window and draining 1,200 ml of a brownish yellow fluid with abundant cellularity. Pericardial biopsy showed infiltration by CD68 (+), CD1a (-) and S100 (-) cells. Twenty-eight months earlier, due to fatigue, dyspnea, and a non-specific inflammatory process, an enhanced-contrast-scan showed that aorta was coated with a hypodense tissue that began near the aortic valve and extended until the inferior mesenteric artery, with stenosis of the left subclavian, celiac axis, renal and upper mesenteric arteries. An angioplasty and stent placing was carried out in the last two arteries. Both kidneys had the appearance of "hairy kidneys". A bone scan showed increased uptake in femurs and tibiae and X-ray examination showed osteosclerosis in metaphysis and diaphysis. The diagnosis of Erdheim-Chester disease (non-Langerhans-cell histiocytosis) was made and the patient was treated with steroids and methotrexate.
