[Adenoid cystic carcinoma of ENT associated with hard lump: a report of 9 cases].
OBJECTIVE
To assess the clinical and pathological features of the patients with ENT adenoid cystic carcinoma (ENTACC) who presented with hard lump, and to detect its prognosis.


METHODS
A retrospective analysis was performed on 9 patients with ENTACC by their clinical data.


RESULTS
The period from the occurrence of primary symptoms to definite diagnosis was 4 years and 3 months on average. All patients were followed up from 6 months to 15 years. All of the cases relapsed after operation and radiotherapy. Five patients died, among which 3 died with lung metastases, 2 with local lymphatic metastases, 1 with bone metastases and 1 with encephalic diffusion. The other 4 cases still survive. The longest survival period with tumor was 6 years and 3 months.


CONCLUSIONS
The pathological result of these 9 cases were all salivary gland derived adenoid cystic carcinoma of solid type. It was mainly characterized by the development of ENT hard lump. All of the patients should be diagnosed in time. Extensive excision and postoperative radiotherapy are needed at the first time. The tumor of solid histological pattern appears with much poorer prognosis compared with that of other histological pattern.
