The anatomopathology of 25 cases of bilharzial cancer is reported involving 20 men and 5 women. The macroscopic studies of the tumors revealed an unifocal, budding and infiltrating pattern. The significant type appeared to be the squamous carcinoma in 13 of the cases. All the 25 cases showed the presence of a bilharzial infestation with several patterns: tumoral clusters of squamous carcinoma and urothelial cells, clusters of scattered signet ring cells, elongated or undifferentiated atypical cells. The chronic inflammatory stroma contained bilharzia ova. The role played by metaplasia of the vesical urothelium is accepted by the majority of authors to explain the histogenesis of theses tumors.
报告了25例血吸虫癌的解剖病理学情况，其中男性20例，女性5例。对肿瘤的宏观研究显示为单灶性、芽状和浸润性模式。13例病例中显著的类型似乎是鳞状细胞癌。所有25例均显示存在血吸虫感染，有几种模式：鳞状细胞癌和尿路上皮细胞的肿瘤性簇、散在印戒细胞簇、细长或未分化的非典型细胞。慢性炎性间质中含有血吸虫卵。膀胱尿路上皮化生所起的作用被大多数作者接受，用以解释这些肿瘤的组织发生。
