Adenoid cystic carcinoma
Discussion (Related Text)
Adenoid cystic carcinoma (formerlycalled cylindroma) is a malignant neoplasm that arises from the tracheal salivary glands and accounts for 40% of primary tracheal malignancies. This neoplasm tends to involve the posterolateral wall of the distal two-thirds of the trachea or main or lobar bronchi. The prognosisin patients with squamous cell carcinoma is poor, as upto 50% of patients have mediastinal extension of tumor at the time of diagnosis. While adenoid cystic carcinoma has a better prognosis, these slow-growing lesions are locally invasive with a tendency toward late recurrence and metastases.
