SKIN-CANCER IN AFRICAN ALBINOS

A review of 775 normally pigmented Africans and 18 African albinos wit h malignant skin tumours showed that squamous cell carcinoma was the m ost common tumour type, in contrast to Caucasians, in whom basal cell carcinoma is most frequent. In African albinos squamous cell carcinoma of the head and neck region was most frequent. However, the proportio n of basal cell carcinomas was low also among albinos but higher than among normally pigmented patients. In contrast to the normally pigment ed patients, there were no squamous cell carcinomas on the limbs in al bino patients. We suggest that this difference was due to environmenta l factors, such as chronic leg ulcers, which might have been less infl uential in the albinos, who seldom lived more than 30 years. No cases of cutaneous melanoma or Kaposi sarcoma were found in the albino group .
