Failure to detect advanced neoplasia is common in a community-based endoscopy facility. Previously undetected advanced lesions are more frequently found in the left colon and rectum. Risk factors for non-detection of advanced adenoma are similar to those for advanced neoplasia recurrence. Lowering non-detection rates is crucial for correct follow-up recommendations. Patients should be aware of rates of detection of advanced neoplasia after previous normal colonoscopic findings.

El hepatoblastoma del adulto es una patología in-usual, de patogenia no bien conocida y de muy mal pro-nóstico. Presentamos un caso de hepatoblastoma del adulto tratado en nuestro centro. Varón de 65 años, sin hepatopatía previa, que con-sulta por dolor en hipocondrio derecho de evolución subaguda. El diagnóstico anatomopatológico fue hepa-toblastoma epitelial del adulto, con bordes quirúrgicos libres. Fue reintervenido 5 meses después por recidiva precoz y falleció 10 meses después del diagnóstico por nueva recidiva masiva. Su diagnóstico definitivo es his-tológico. La cirugía radical ofrece el único tratamiento que aumente la supervivencia, pero frecuentemente recidiva. No existen pautas bien definidas de quimiote-rapia adyuvante, ni experiencia en trasplante. Palabras clave. Hepatoblastoma. Tumores hepáticos primarios. Adulto. abstRact Adult hepatoblastoma is a rare pathology. Its pathogeny is not well understood and prognosis is very bad. We present a case of adult hepatoblastoma treated in our centre. A 65 year-old male, without previous hepatopathy, who consulted due to right hypochondrial pain with a subacute evolution. The pathological diagnosis was adult epithelial hepatoblastoma, with free surgical margins. The patient received a second surgical intervention 5 months later due to early recurrence and died 10 months after the diagnosis due to a new massive recurrence. His definitive diagnosis is histological. Radical surgery is the only treatment that increases survival, but recurrence is frequent. There are no well-defined patterns of adjuvant chemotherapy nor is there any transplant experience.
