A 40-year-old woman was diagnosed with unicentric Castleman disease of hyaline vascular variant after thoracic surgery. She was admitted to our hospital because of slight chest distress for 9 months. Contrasted chest CT showed a well-defined and homogeneous enhanced mass in the right hilum, with coarse calcification (A-C). It was almost normal under the examination of bronscopy and the transbronchial needle aspiration (TBNA) biopsy of the right hilar mass showed chronic inflammation. Whole resection of the mass was performed and prominent diffuse proliferation of lymphoid cells with central hyalinized vascular structures was showed pathologically (D, Hematoxylin and eosin, ×200). she was diagnosed with Castleman disease of hyaline vascular variant. Chemotherapy was not suggested. she had been alive without recurrence for 7 years.
