ABSTRACT
Background: hereditary colorectal cancer non-related to polyposis associated to extraintestinal neoplasias is called syndrome of Lynch type II and its diagnosis constitutes a challenge for medical staff. Objective: to make possible through a case presentation the clinical thought and the scientific up-dating in this entity to make a more accurate diagnosis. Case presentation: a forty –nine years old patient was admitted for a palpable mass on the left iliac fossa and hypogastrium. A surgical reception was carried out and a papillary mucinous cystadenocarcinoma of ovary was diagnosed for which chemotherapy was prescribed. Two years she was admitted for lower hemoabdomen pain, asthenia, dizziness and cutaneous mucosa paleness. After another surgery a sigmoid colon adenocarcinoma was diagnosed. Later the patient died due to a bleeding and multiorgan failure. Conclusions: based on the criteria of Amsterdam and Bethesda a diagnosis was made of a syndrome of Lynch type II. Due to the frequency of the non-polyposic hereditary variant of the colorectal cancers it is mandatory an integral evaluation of the patient and a coherent clinical judgment in order to improve the diagnostic certainty in a syndrome which is not infrequent but poorly diagnosed.REFERENCES
