Enfermedad de Castleman, un diagnóstico diferencial que no se debe olvidar en los tumores de mediastino.

Castleman disease is an uncommon lymphoproliferative disorder which can be unicentric or multicentric. Hialine vascular variant is the most common pathologic form, which is usually unicentric and presenting as mediastinal tumors. We report a 31 years old female with a history of retrosternal pain. A chest CAT scan showed a tumor in the posterior mediastinum. The patient was operated and the tumor excised. The pathology report showed a Castleman disease. No other tumors were found in the patient, who had a favorable evolution.
