RESUMEN
Two hundred and fifty five vesical carcinomas in Sudanese patients are analysed as regards frequency, age, sex, local geographical distribution, morphological features and association with urinary schistosomiasis. The findings are compared with those from other series. It is concluded that the pattern of bladder cancer in the Sudan in general conforms to that reported from regions endemic for schistosomiasis and differs significantly from that seen in non-schistosomal regions. The limitations in the study are noted.

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.
