Carcinoma of the penis in Uganda.

Carcinoma of the penis is the commonest cancer of males in Uganda, particularly among the different uncircumcised ethnic groups. The great variations in frequency among those groups, however, suggest that other factors may play an important role. These factors may be infections, so that circumcision may act only by permitting better penile hygiene. Condylomata acuminata are also common in Uganda and can resemble carcinoma both clinically and histologically.
