Cronkhite-Canada syndrome (CCS) is a rare nonfamilial polyposis syndrome characterized by epithelial disturbances both in the gastrointestinal tract and in the epidermis. The pathologic finding of the polyp is usually a hamartomatous polyp of the juvenile type; however, the possibility of serrated adenoma associated malignant neoplasm was reported in some Japanese cases. Up till now in South Korea, 13 CCS cases have been reported, but there was no case accompanied by the colon cancer. We report the first case of CCS associated with malignant colon polyp and serrated adenoma in Korea. A 72-year-old male patient who complained of diarrhea and weight loss was presented with both hands and feet nail dystrophy, hyperpigmentation, and alopecia. Endoscopic examination showed numerous hamartomatous polyps from the stomach to the colon. The pathologic results confirmed colon cancer and serrated adenoma.

Cowden's disease, also known as a kind of phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome, is an uncommon autosomal dominant inherited complex disorder with various hamartomatous growths of multiple organs involving all three germ cell layers. It usually manifests with polyps throughout the gastrointestinal tract, ranging anywhere from 30% to 85%, and more common extra intestinal findings. Mucocutaneous lesions like facial trichilemmomas, acral keratoses, papillomatous papules and macrocephaly, and malignancies including breast, thyroid and endometrial carcinoma are the hallmark of the disease. Here we report on familial Cowden's diseases case of a 52-year-old male proband with mucocutaneous lesions and mutation on the
