Superficial Cancer in the Sudan. A Study of 1225 Primary Malignant Superficial Tumours

Superficial cancer in the Sudan accounted for 17·2% of all malignant tumours examined histologically during the period 1962-72 inclusive. Of the 4 pathological types studied, squamous cell carcinoma was the commonest (63·3% of all superficial cancers) followed by malignant melanoma (18·8%) and basal...

Sumario:Superficial cancer in the Sudan accounted for 17·2% of all malignant tumours examined histologically during the period 1962-72 inclusive. Of the 4 pathological types studied, squamous cell carcinoma was the commonest (63·3% of all superficial cancers) followed by malignant melanoma (18·8%) and basal cell carcinoma (14·9%) whilst Kaposi's sarcoma formed only 3% of the total. Generally, twice as many cases occurred in males as in females, with the exception of Kaposi's sarcoma where all the patients were males. Although a relatively high proportion of cases occurred in the young age groups, the age-specific incidence was noted to increase with age. Similarities and differences in the anatomical site of tumours compared with European and African series were noted. Certain differences emerged in the geographical distribution of these tumours in the Northern and Southern regions of the Sudan—regions which differ both ethnologically and geographically—thus suggesting possible roles played by racial and environmental factors in this respect.
