[Cystic adenoid carcinoma of the larynx: two cases]
Abstract
Adenoid cystic carcinoma is the most common malignant tumor of the minor salivary glands in the head and neck. Laryngeal localization is rare due to the poor distribution of the accessory salivary glands in this area. It arises exceptionally before 20 years and no risk factor is known. Diagnosis is a histological finding because symptoms do not differ greatly from other laryngeal tumors. Histological features, stage, quality of tumor resection and nerve invasion are prognostic factors. These tumors grow slowly and local recurrence or systemic metastasis are exceptional. Surgery is the treatment of choice but outcome is always fatal, after a long clinical course in many patients.
