Description
Squamous cell carcinoma accounts for approximately 90% of oral malignancies. The objective of this study was to document the gender, age, sub-site distribution and histologic differentiation of squamous cell carcinoma of the oral cavity, maxillary antrum and lip in a Zimbabwean population. Hospital records of patients with a histologic diagnosis of squamous cell carcinoma of the oral cavity, maxillary antrum and lip seen at Harare Central Hospital and Parirenyatwa Hospital in Zimbabwe during the period January 1982-December 1991 were reviewed. 20.8% (n = 358/1723) were squamous cell carcinoma of the oral cavity, maxillary antrum and lip. Age ranged from 3 to 70 years with a 2:1 male:female ratio. Peak incidence in both sexes were in the 41-50 and 51-60 years age groups. Sub-site distribution was mandibular gingiva 18.4%, tongue 17.9%, floor of the mouth 16.2%, maxillary gingiva 9.2%, buccal mucosa 9.2%, maxillary antrum 12.6%, hard palate 7.8%, soft palate 4.8%, lower lip 2.8% and upper lip 1.1%. 64.8% were well differentiated, 24.8% moderately differentiated and 10.4% poorly differentiated. The mandibular gingiva, floor of the mouth and tongue were most commonly affected. Lip squamous cell carcinoma was uncommon. Well-differentiated squamous cell carcinoma was most common in the 41-60 years age group. © 2005 Elsevier Ltd. All rights reserved.
