title: Paraneoplastic syndrome and intrathoracic Castleman disease.
abstract: We report two cases of intrathoracic Castleman disease presenting with paraneoplastic syndrome. Patient 1 was a 10-year-old girl with short stature. She was found to have delayed bone age, slow growth velocity, and iron-deficiency anemia, which was refractory to treatment. Thrombocytosis and hypergammaglobulinemia were later detected. Chest X-ray revealed a hilar mass. Patient 2 was a 14-year-old boy who had severe cough, progressive mucocutaneous erosion, and dermatitis. Chest X-ray showed a mediastinal mass. Sections of skin biopsy showed findings consistent with pemphigus disease. In each case, the histological diagnosis of Castleman disease was made.
