[ tracheal adenoid cystic carcinoma]

ABSTRACT

Adenoid cystic carcinoma [CACC], also called cylindroma, are rare epithelial malignant tumors, their favorite seat is at the salivary glands [95% of cases], they represent 20 to 40% of tracheal carcinoma and 0,1% of respiratory tract cancers. Bronchial localization is rare, estimated only between 0.3 and 2%. This is a retrospective study ranging from 1997 to 2006 concerning five patients treated in the thoracic surgery department, for tracheal tumor and whose final histological diagnosis was in favor of adenoid cystic carcinoma [ACC]. All the patients had inspiratory dyspnea. Bronchoscopy showed a smooth tracheal tumor, the biopsy revealed a ACC. Four of our patients underwent resection of the tumor-by-end anastomosis and one patient was deceased prior to surgery. Adjuvant radiotherapy was indicated in one case. The short term, outcome was good, but local recurrence with lung and cervical lymph node metastases appeared after 6 years in one patient. The adenoid cystic carcinoma of the trachea is a rare tumor. Its diagnosis and surveillanse based on bronchial Bibroscopy combined with biopsy. CT better evaluates the scope and extent of the peri tracheal tumor. The therapeutic management is based mainly on surgery combined with radiotherapy. adenoid cystic carcinoma of the trachea are rare malignant tumors issues to think about before a lesion at this level
