Pulmonary glomus tumour: a case initially diagnosed as carcinoid tumour

Respirology. 2002 Dec;7(4):369-71. doi: 10.1046/j.1440-1843.2002.t01-1-00385.x.

Abstract

Pulmonary glomus tumours are rare lesions, with few cases reported previously. Herein, we present the clinical and pathological features of a case of pulmonary glomus tumour. A 29-year-old female patient presented to our clinic complaining of cough, dyspnoea and left-sided chest pain. Computed tomography (CT) of the thorax revealed a nodular lesion causing obstruction of the left main bronchus. Fibreoptic bronchoscopy demonstrated a polypoid mass occluding the left main bronchus 10 mm distal to the main carina. Bronchoscopic biopsy was interpreted histologically as carcinoid tumour. Bronchotomy plus mass extirpation was performed with left thoracotomy. Microscopically, a tumoral structure composed of uniform cells with a round centrally located nucleolus and narrow eosinophilic cytoplasm was seen. Thin-walled vessels lined with endothelium were interspersed between tumoral structures. The cells were stained chromogranin and cytokeratin negative and strongly vimentin positive. The pathological diagnosis for the thoracotomy specimen was pulmonary glomus tumour. Follow-up chest CT was negative for recurrent tumour and the patient remains free of disease 17 months after surgery.
