Adenosquamous carcinoma is an uncommon, controversial neoplasm. To further comprehend its natural history, the clinical and pathological features of 12 new cases were reviewed and analyzed collectively with those described in the English literature.


Twelve cases of adenosquamous carcinoma of the upper aerodigestive tract with adequate follow-up and available microscopic slides and paraffin tissue blocks were identified in the anatomic pathology files of Presbyterian Hospital of the University of Pittsburgh Medical Center over the period 1983-2001.


The 8 men and 4 women ranged in age from 34 to 81 years (mean, 62.8 years). The larynx (5 cases) and the floor of the mouth (4 cases) were the most common sites of origin. Nine patients had cervical lymph nodes positive for carcinoma (8 at diagnosis), 7 experienced local recurrences, and 2 developed distant metastases. Four of 10 (40%) patients with follow-up died of disease. Combining our cases with those in the literature (total of 58 cases) revealed similar findings: 64.7% were associated with positive cervical lymph nodes, 46.7% experienced local recurrences, 23.1% developed distant metastases, and 42.9% died of their disease at a mean follow-up period of 24.7 months.


Adenosquamous carcinoma is an aggressive neoplasm with a tendency for early lymph node metastasis, frequent local recurrence, occasional distant metastasis, and death from disease, usually within 2-3 years. Surgery with neck dissection is the treatment of choice.
