Abstract
A 24 year old male presented with a history of recurrent bronchopulmonal infections. Chest computed tomography was performed, revealing a right central mass. In the following bronchoscopy and ultrasound guided needle aspiration of the tumour no specific diagnosis could be obtained. Due to the central location of the tumour thoracotomy and middle lobe resection was performed. Histopathological analysis revealed an intrapulmonary, subpleural located Morbus Castleman of the hyaline-vascular type.Castleman’s disease is a very rare disorder of the lymphatic tissue that is differentiated into two clinical subtypes. The localized type presents histologically almost always as the hyaline-vascular form. Findings have been reported in mediastinal lymph nodes, the abdomen and peripheral lymphnodes. Intrapulmonary development is very rare and only 9 cases have previously been described in literature.On the other hand the multicentric type accounts for approximately 10%–15% of cases and histologically usually presents as the plasma cell variant. It is accompanied by fatigue and general weakness and often requires systemic steroid or chemotherapy.The localized type develops less clinical symptoms and is curable by complete surgical resection.
