ABSTRACT

Os tumores de traqueia são raros e podem ser de difícil diagnóstico, por mimetizarem outras afecções pulmonares de caráter obstrutivo, como asma e DPOC. Relatamos um caso de lipoma de traqueia em uma paciente que fora tratada para asma e DPOC, sem resposta adequada, até apresentar complicações infecciosas. A presença do tumor foi sugerida por TC de tórax e confirmada por fibrobroncoscopia. A paciente foi submetida à ressecção endoscópica do tumor; porém, evoluiu para o óbito por pneumonia e choque séptico.


Tracheal tumors are rare and can be difficult to diagnose due to their capacity to mimic other obstructive lung diseases, such as asthma and COPD. We report the case of a female patient with a tracheal tumor. She had previously been treated for asthma and COPD, with little response to the treatment. The onset of infectious complications prompted further investigation. Chest CT images suggested the presence of a tumor, which was confirmed by fiberoptic bronchoscopy. The tumor was endoscopically resected. However, the patient evolved to death due to pneumonia and septic shock.

ABSTRACT

A esquistossomose é uma doença que, no Brasil, é causada pelo Schistosoma mansoni e transmitida através da água por moluscos do gênero Biomphalaria. Essa espécie ocorre na África, nas Antilhas e na América do Sul. O parasita, ao atingir a fase adulta de seu ciclo biológico no sistema vascular do homem, alcança as veias mesentéricas. Cada fêmea põe cerca de 400 ovos por dia, e estes, a partir da submucosa, chegam à luz intestinal. Há relatos de casos a respeito de ovos de S. mansoni nos pulmões de pacientes sem evidência de fibrose hepática. Relatamos um caso dessa forma atípica de apresentação da doença. O paciente apresentava dor torácica não-ventilatóriodependente, perda ponderal significativa e tosse seca. A TC de tórax mostrou uma tumoração irregular no lobo inferior esquerdo, mas somente a biópsia pulmonar evidenciou ovos de S. mansoni degenerados. O paciente não apresentava sinais clínicos de hipertensão pulmonar ou portal, as quais tampouco foram diagnosticadas através de exames.


Schistosomiasis is a disease that, in Brazil, is caused by Schistosoma mansoni and is transmitted by snails of the genus Biomphalaria. This species occurs in Africa, the Antilles and South America. The parasite, developing to the adult stage in the vascular system of the host, migrates to the mesenteric veins. Each female lays approximately 400 eggs per day, and these travel from the submucosa to the intestinal lumen. There have been reported cases in which S. mansoni eggs were identified in the lungs of patients with no evidence of liver fibrosis. We report a case with this atypical presentation of the disease. The patient presented nonpleuritic chest pain, significant weight loss and dry cough. A CT scan revealed an irregular tumor in the left lower lobe. However, a lung biopsy revealed non-viable S. mansoni eggs. The patient presented no clinical signs of pulmonary or portal hypertension; nor was either identified through diagnostic tests.
