BACKGROUND: Basal cell adenoma (BCA) and pleomorphic adenoma (PA) are among the most common benign neoplasms of the salivary glands. The aim of this study was to analyze and compare the diagnosis, treatment, and recurrence rate of these two different types of parotid benign tumors.
METHODS: A retrospective analysis of all cases of parotid gland BCA and PA surgically treated between January 1, 1990, and December 31, 2019, was performed at our university.
RESULTS: A total of 349 patients were enrolled in the present study, 311 of which (89.1%) were affected by PA, and 38 patients (10.9%) by BCA. The most frequently performed surgery was partial parotidectomy for both groups (85.9% in PA and 65.8% in BCA). Perioperative complications - often transient and of short duration - occurred within 48 hours of surgery and were observed in 30.6% of PA patients and in 18.4% of BCA patients; furthermore, recurrences were noticed in 19 PA patients (6.2%) and in 3 BCA patients (7.9%) (rates in range with the available literature data).
CONCLUSIONS: To the best of our knowledge, this study is one of the largest single-center series in the literature comparing diagnosis, treatment, recurrence rate and clinical-pathological features of two different types of benign parotid gland tumors, BCA, and PA.
