A resected case of Castleman's disease in the chest wall

Abstract

Castleman's disease arising in mediastinal or hilar nodes is common, but lesions in the chest wall are rare. A 40-year-old male who complained of cough was found to have an abnormal shadow on a chest roentgenogram. Chest CT demonstrated the chest wall tumor as a 7.2 × 4.0 × 3.6 cm homogeneous mass in contact with the posterior pleura at the right 10th intercos-tal space. The CT number of the tumor was 30. MRI T2 weighted image demonstrated the tumor to be a hyperintense lesion. Preoperatively, the tumor was diagnosed as a neurogenic neoplasm in the chest wall. It was resected through a limited thoracotomy with a video-assist. Histopathological examination demonstrated the hyaline vascular type of Castleman's disease. The patient recovered uneventfully, and was discharged 10 days after surgery.
