title: Lip cancer in Zimbabwe. Report of 14 cases.
abstract: Lip cancer, relatively common among fair-skinned males, is uncommon among Black-skinned males. In a 10-year review period of 358 Black African patients with orofacial squamous cell carcinoma, 3.9% (n = 14) were found on the lip with a male to female ratio of 2.5:1. Fifty percent (n = 7) of the patients were albinos and two were children with xeroderma pigmentosum. The lower lip was most commonly affected (78.6%). The well-differentiated and moderately differentiated histopathologic types each comprised 42.9% of the lesions. Alcohol consumption and tobacco usage was admitted to in 42.9% (n = 6) of the patients.
