Zusammenfassung
Primäre Trachealtumore sind selten und verursachen meist erst dann Beschwerden, wenn der Tumor den größten Anteil des Tracheallumens okkludiert hat. Wir berichten über eine 45-jährige Patientin mit pulmonaler Tuberkulose und einem Tumor in der Trachea, der als Einbruch eines tuberkulösen Lymphknotens in die Trachea gedeutet worden war. Eine erneute Bronchoskopie zeigte eine weißliche, glänzende, blumenkohlartige Raumforderung in der ventralen Trachealwand, die durch die histologische Untersuchung als gutartiger Granularzelltumor eingestuft wurde. Nach der kulturellen Konversion der Tuberkulose, die erst zur Entdeckung des Trachealtumors geführt hatte, wurde der Granularzelltumor vollständig chirurgisch entfernt. Granularzelltumore kommen in der Trachea sehr selten vor, können multifokal vorkommen und maligne entarten. Die komplette Resektion ist die Therapie der Wahl und Rezidive sind selten.
Abstract
Primary tracheal tumours are rare and often only cause symptoms at a late stage, when the tumour obstructs most of the tracheal lumen. We report the case of a 45-year-old woman with pulmonary tuberculosis and a tumour in the trachea, which had been interpreted as a tuberculous lymph node perforating the tracheal wall. Bronchoscopy revealed a white, glossy, papillomatous lesion in the ventral wall of the trachea, which was identified by histology as a granular cell tumour. After culture conversion of the underlying tuberculosis, which led to the detection of the lesion, the tumour was surgically removed. Granular cell tumours rarely appear in the trachea, they may be multifocal and sometimes follow a malignant course. Complete resection is the treatment of choice and recurrence rates are low.
