A clinico-pathologic study of 311 intra-oral salivary gland tumors in Thais

Background:  There have been several epidemiologic studies on intra-oral salivary gland tumors in several countries, but little is known of these tumors in Thailand.
Objectives:  To determine the relative frequency and distribution of various types of intra-oral salivary gland tumors in the Thai population.
Methods:  The files of the Department of Oral Pathology, Faculty of Dentistry, Chulalongkorn University, from 1969 to 2007 were searched for intra-oral salivary gland tumors. Histopathologic slides were reviewed and reclassified according to the 2005 WHO Classification of Head and Neck Tumors. The age, gender, race, and anatomical distribution of the tumors were collected from the patients' records.
Results:  Of the 16,358 accessioned cases, 311 cases (1.90%) were diagnosed as intra-oral salivary gland tumors. One hundred and forty-seven cases (47.27%) were benign tumors, while 164 cases (52.73%) were malignant tumors. The mean age of the patient ± SD = 41.57 ± 16.65 years. Females outnumbered male patients by a ratio of M:F = 1:1.38. Almost all except one patient were Thais. Pleomorphic adenoma was the most common intra-oral salivary gland tumor. The majority of cases occurred at the palate.
Conclusions:  Pleomorphic adenoma is the most common intra-oral salivary gland tumor and the most common benign intra-oral salivary gland tumor, while mucoepidermoid carcinoma is the most common malignant intra-oral salivary gland tumor. Intra-oral salivary gland tumors in Thailand elicit similar trend as in previous studies, with only minor differences such as the ranking of some tumors, the higher incidence of intra-bony location, and the lower incidence of polymorphous low-grade adenocarcinoma.     

Salivary gland tumors in an Iranian population: a retrospective study of 130 cases.

PURPOSE: Tumors of the salivary glands are uncommon, comprising 3% to 10% of head and neck neoplasia. In the absence of epidemiologic studies of these neoplasms in an Iranian population, we conducted a preliminary survey of 130 cases over the last 20 years in Hamedan, Iran. PATIENTS AND METHODS: The medical records and case notes of all patients with histologically confirmed salivary gland tumors were reviewed retrospectively from February 1984 to March 2003. This review found 89 patients with benign tumors and 41 patients with malignant tumors. The collection of data included gender, age, location, and histopathology of the tumor. Other recorded data included diagnostic procedures, operative reports, complications, additional treatment, and follow-up. RESULTS: We studied 78 females and 52 males with a mean age of 44.9 years. Patients with benign and malignant tumors presented with a mean age of 41.3 and 47 years, respectively. The frequency of benign tumors was 68.4% (n = 89) and 31.6% for malignant tumors (n = 41). Tumors were localized in the parotid gland (63%; n = 82), the submandibular gland (23%; n = 30), and in the minor salivary glands (14%; n = 18). The most common benign tumor was pleomorphic adenoma (65.4%; n = 85). Among malignant tumors, mucoepidermoid carcinoma was the most frequent (11.5%; n = 15), followed by adenocarcinoma (10%; n = 13). Greater than 63% of malignant tumors were treated surgically, and the remaining with combined therapy. Seven patients died over the follow-up period (6 with persistent disease), 5 were lost to follow-up, and 23 remained cancer-free. CONCLUSION: Between benign and malignant salivary gland tumors, frequency of pleomorphic adenoma and mucoepidermoid carcinoma was in keeping with studies reported previously. In other salivary gland tumors, however, diversity was obvious and showed significant difference, requiring further studies.     

Tumors of the intraoral minor salivary glands: a demographic and histologic study of 426 cases

In a demographic and histologic study of 426 oral minor salivary gland tumors, 57.5% were classified as benign and 42.5% were classified as malignant or potentially malignant. There was an overall female preponderance (1.59/1). The mean age for females was 53.1 years and for males was 50.6 years. The mean age for patients with malignant tumors was 5.4 years greater than for patients with benign tumors and was statistically significant. The palate was the most common site for oral minor salivary gland tumors followed by the upper lip and the buccal mucosa. These three sites accounted for 76.1% of all cases. Pleomorphic adenoma was the most common benign tumor (41% of all cases and 71% of benign tumors) followed by monomorphic adenoma of the canalicular and basal cell subtypes (10% of all tumors and 18.9% of benign lesions). Mucoepidermoid carcinoma was the most commonly encountered malignant tumor, accounting for 15.2% of all tumors and 35.9% of malignant lesions. Low-grade (terminal duct, lobular, polymorphous) adenocarcinoma was the most second most common type, making up 11% of all tumors and 26.4% of all malignant tumors. The results of this study are compared with other recent studies.     

A retrospective study of 60 cases of salivary gland tumors in a Thai population.

Sixty cases of salivary gland tumors were diagnosed in the Oral Pathology Department, Faculty of Dentistry, Mahidol University, Bangkok, Thailand, from 1973 to 2002. Fifty-two cases (86.7%) involved the intraoral minor salivary glands, six cases (10%) were found in the major glands, and two cases (3.3%) were intrabony. The predominance of malignant over benign tumors was evident with 68.3% being malignant and 31.7% benign. Patients ranged in age from 9 to 75 years. The female to male ratio of benign intraoral salivary gland tumors was 1.4 to 1 and of malignant types was 1.1 to 1. The principle site of occurrence was the palate (65.4%), followed by buccal mucosa (13.5%). Pleomorphic adenoma (30%) was the most common benign tumor, and mucoepidermoid carcinoma (44.3%) was the most common malignant tumor. Comparing the data from the present study with other series, some discrepancies exist.     

Salivary gland tumors in a Brazilian population: a retrospective study of 496 cases

Salivary gland tumors are uncommon and the microscopical features can be complex. Epidemiological data of these tumors in the various parts of the world can be helpful for a better understanding of its biology and clinical characteristics. In this study, 496 epithelial and mesenchymal tumors of major and minor salivary glands diagnosed at Londrina Cancer Institute during the period from 1972 to 2001 were reviewed. Out of all cases, 335 (67.5%) were classified as benign and 161 (32.5%) as malignant. The majority of the cases occurred in the parotid gland (67.7%), followed by the minor salivary glands (22.8%) and submandibular gland (9.5%). Among the minor salivary gland tumors, the palate was the most frequent location (67%). The tumors affected more commonly adult patients with peak incidence between 40 and 50 years of age and with a slightly predominance in females. Pleomorphic adenoma was the most frequent tumor representing 54.2% of all cases, followed by mucoepidermoid carcinoma (13.5%), Warthin's tumor (8.5%) and adenoid cystic carcinoma (7.9%).     

Intraoral minor salivary gland tumors: a review of 75 cases in a Libyan population

Minor salivary gland carcinomas are uncommon but most often occur in the oral cavity, particularly the hard palate. Dental examination may provide an opportunity for early detection. During the period of 1977-2000 a group of 75 patients (31 males and 44 females, median age 44.2 years and range 15-86 years) with minor salivary gland tumors were diagnosed, based on the 1991 WHO classification. The peak occurrence of the tumors was in the fifth decade for males and sixth decade for females. The frequency of benign tumors was 38.6% (n = 29) and malignant tumors 61.3% (n = 46). Pleomorphic adenoma was the most common histological type of benign tumor identified whereas mucoepidermoid carcinoma and adenoid cystic carcinoma were the most common malignant tumors. The most common primary location of the tumors was the palate followed by the cheek. A benign tumor usually presented as an asymptomatic swelling and ulceration, pain being more frequently associated with the malignant tumors. This study shows that intraoral tumors of minor salivary glands vary widely in presentation, and should be taking into account by medical and dental practitioners in any differential diagnosis when assessing intraoral pathology. Any lesion arising from the hard palate (the most common site in this series) should be considered as a possible minor salivary gland tumor. Referral to a multidisciplinary head and neck clinic following diagnosis is strongly recommended.

Intraoral minor salivary gland neoplasms: review of 213 cases.

PURPOSE: Minor salivary gland tumors (MSGTs) constitute a heterogeneous group of neoplasms with great histomorphologic variation. This study reviews a large series of benign and malignant salivary gland tumors of the oral region and determines the incidence and the correlation of the histopathologic features with the clinical characteristics. MATERIALS AND METHODS: Two hundred thirteen cases of MSGT were retrospectively studied. Hematoxylin-eosin-stained slides were examined in all cases. Special stains and immunohistochemical stains were used in selected cases. Clinical characteristics of the neoplasms were also noted. RESULTS: One hundred nineteen tumors were benign (56%), and 94 tumors were malignant (44%). Pleomorphic adenoma was the most common benign tumor (93 of 119). Canalicular adenoma was the second most common benign MSGT in our series (25 of 119). Of the 94 malignant MSGTs, mucoepidermoid carcinoma (MEC) (45 of 94), adenoid cystic carcinoma (22 of 94), and polymorphous low-grade adenocarcinoma (18 of 94) were the most common. Most MECs (34 of 45) were low-grade lesions. Of 5 central MECs, 3 cases occurred in the maxilla and 2 cases arose in the mandible. CONCLUSIONS: Benign intraoral MSGTs are slightly more common than malignant MSGTs. Pleomorphic adenoma is the most common MSGT, and MEC is the most common malignant variety. The palate is the most common site for minor gland neoplasms. Benign labial salivary gland neoplasms are more common in the upper lip, and malignant labial tumors are more common in the lower lip.
