ABSTRACT

A doença de Castleman é um distúrbio linfoproliferativo atípico, de etiologia desconhecida, que pode estar associada a uma série de condições clínicas, inclusive doenças de caráter autoimune e neoplasias malignas. No presente relato, uma paciente de 72 anos foi encaminhada ao serviço de cirurgia torácica do Hospital Universitário Getúlio Vargas, localizado na cidade de Manaus (AM) para a ressecção de um tumor de mediastino posterior. Três meses antes, havia sido internada em UTI com um quadro de dispneia intensa, ocasião na qual foi diagnosticada miastenia gravis. Após a ressecção da massa mediastinal, a análise histopatológica revelou doença de Castleman hialino-vascular complicada por sarcoma de células dendríticas foliculares. Até o momento da redação deste estudo, a paciente utilizava um anticolinesterásico e corticoides para o controle da miastenia gravis.


Castleman's disease is an atypical lymphoproliferative disorder of unknown etiology, which might be associated with various clinical conditions, including autoimmune diseases and malignant neoplasms. We report the case of a 72-year-old female patient who was referred to the thoracic surgery department of Getúlio Vargas University Hospital, in the city of Manaus, Brazil, for the resection of a posterior mediastinal tumor. Three months prior, the patient had been admitted to the ICU with signs of severe dyspnea, at which time she was diagnosed with myasthenia gravis. After the resection of the mediastinal tumor, the histopathological examination revealed hyaline vascular-type Castleman's disease, complicated by follicular dendritic cell sarcoma. At this writing, the patient was being treated with an anticholinesterase agent and corticosteroids for the control of myasthenia gravis.
