Tubulopapillary carcinoma (De-novo-carcinoma)
Tubulopapillary carcinoma This is a de-novo-carcinoma with a diameter of 1,5 cm. Most carcinomas originate from adenomas (adenoma-carcinoma-sequence). The cause of the de-novo-carcinomas is unknown. Correlations to HNPCC, ulcerative Colitis and non tropical sprue are reported. On the other hand flat adenomas were identified as precursors, thus questioning the hypothesis of de-novo-carcinogenesis. HNPCC = Hereditary Non Polyposis Colorectal Carcinoma
