Maladie de Castleman: Localisation inhabituelle du thorax

La maladie de Castleman est une affection rare qui peut toucher le thorax. La localisation diaphragmatique est exceptionnelle. Nous rapportons le cas d’une patiente de 47 ans, chez qui une thoracotomie exploratrice a permis l’exérèse d’une masse du sinus médiastinal antérieur droit, en continuité avec le diaphragme et dont l’histologie est en faveur de la maladie de Castleman de type hyalino-vasculaire. Les particularités cliniques,radiologiques et évolutives ont été revues.Key words: Maladie de Castleman, localisation, thorax, exérèse, chirurgi

Adenoid cystic carcinoma of the trachea: A clinico-pathological analysis

Primary malignant tracheal tumors are not common and adenoid cystic carcinoma (ACC) of trachea is very rare. The diagnosis is often delayed due to the atypical symptoms. We report an extremely rare case of ACC of proximal trachea, in a 55-year-old female who presented with a 12 month history of progressive dyspnea. Laryngoscopy and computed tomography revealed a broad-based polypoidal mass arising from posterior wall of the proximal  trachea. Biopsy confirmed the diagnosis of ACC. The patient underwent a  complete surgical resection and post operative radiotherapy. Six months  follow-up of the patient did not reveal local recurrence or distant metastases. The literature of tracheal ACC is reviewed
