Hereditary non polyposis colorectal cancer (hnpcc) also known as lynch syndrome (ls), is an autosomal dominant cancer syndrome. besides colorectal cancers, it predisposes patients to extracolonic cancers. despite several extracolonic cancers have been reported on ls, we found a new face of it. a 43-year-old g2l2 patient with chief complaint of abnormal uterine bleeding.  her endometrium biopsy showed clear cell carcinoma, and the necessary work-ups have been done. but the patient’s family history demonstrated hnpcc based on the amsterdam 2 criteria. after some years, the patient presented to our hospital for fever, shivering and abdominal luq pain. spiral ct scan showed a solid cyst with heterogeneous enhancement in the spleen, and hepatosplenomegaly. in this paper, another case with endometrial cancer as a sentinel cancer of ls is reported. this fact implicate that physicians should notice the family history of malignancies in patients with gynecologic cancers and consider ls.
