Title: Evaluation of the histopathology of orofacial lesions in a North-East Nigerian tertiary centre

Page 105; Abstract (Result section) line 6 and 11

Results: A total of 102 (51.3%) benign lesions, 59 (29.6%) malignant lesions and 38 (19.1%) inflammatory/reactive lesions were seen. The common benign neoplasms were ameloblastoma (23.5%), fibrous dysplasia (15.7%) and pleomorphic adenoma (13.7%). The malignant lesions were mainly well differentiated squamous cell carcinomas (28.8%) and terminal duct carcinoma (11.9%). Inflammatory lesions comprised mainly of chronic osteomyelitis (15.8%) and non-specific chronic inflammatory lesions; giant cell granulomas, granulation tissues which constituted 10.5% each. The addition of each section is wrong. There were 104 (52.3%) males and 95 (47.7%) females giving a male: female ratio of 1.1:1. The mean age of the patients was 36.1(SD΁18.9) years with a range of 1 to 85 years. Most tissue specimens were soft tissues (61.3%), while bone specimen accounted for 15.6% of all specimens analysed. There were 62 (31.2%) mandibular lesions, 24 (12.1%) palatal lesions and 15 (7.5%) parotid lesions, while maxillary antral lesions were the least, constituting only 0.5% of all lesions studied. The addition of each section is wrong.
