Resumo O tumor de células granulares é uma neoplasia de origem mesenquimatosa, quase sempre benigna, mas com tendência a recidivar. Embora surja com maior frequência na cabeça e no pescoço, tem sido descrito em quase todas as áreas do corpo. A sua ocorrência no pulmão é extremamente rara. Os autores descrevem dois casos de tumores endobrônquicos de células granulares, discutem os aspectos particulares desta patologia, bem como as modalidades terapêuticas utilizadas, com particular ênfase no uso da excisão e crioterapia endobrônquica.
A 50-year-old male smoker (30 pack-years), a car salesman with a history of arterial hypertension and dyslipidemia, sought medical attention. The patient was under regular treatment with simvastatin (20 mg), valsartan (80 mg), lansoprazole (30 mg), and brotizolam (0.25 mg). The patient was referred to a pulmonologist due to the finding of right paratracheal lesion with enlargement of the upper mediastinum on a routine chest X-ray (Figure 1).The patient was asymptomatic and presented no significant alterations upon physical examination-normal pulmonary auscultation and normal peripheral oxygen saturation. In addition, there was no jugular swelling at 45°.Pulmonary function tests revealed no alterations, and echocardiography was normal. Computed tomography of the chest revealed a right paratracheal mediastinal tumor,
Granular cell tumor is a mesenchymal neoplasm almost always benign, with tendency to recurrence. Although it is more frequent in in the head and neck it has been described in almost all areas of the body. Its occurrence in the lung is extremely rare. The authors describe two cases of endobronchial granular cell tumours, discuss the particularities of this pathology as well as the treatment options, with particular attention to the use of endobronchial excision and criotherapy.
Bronchopulmonary sequestration (BPS) is a rare malformation of the lower respiratory tract. It consists of a non-functioning mass of lung tissue that lacks normal communication with the tracheobronchial tree and that receives arterial blood supply from the systemic circulation. It is classified as intralobar (ILS) or extralobar (ELS) according to its location within or outside the normal lung. Most sequestrations are intralobar (75%) and occur predominantly in the left lower lobe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
