Cow·den dis·ease
(kow'dĕn), [MIM*158350]Cowden syndrome
A rare autosomal dominant genodermatosis (OMIM:158350) characterised by multiple hamartomas arising from all three germ cell layers, most prominently from the ectoderm and endoderm, in particular hamartomas of skin and the GI tract (from the stomach to the colon) and an increased risk of cancer (e.g., breast, thyroid (papillary or follicular), uterus and osteosarcoma). Women with Cowden syndrome have up to a 50% lifetime risk of developing breast cancer; 75% have benign breast disease (fibroadenomas, fibrocystic changes).A rare autosomal dominant hamartoma/neoplasia syndrome [MIM 158350] characterised by multiple hamartomas—which arise from all three germ cell layers, most prominently from the ectoderm and endoderm, in particular hamartomas of skin and the GI tract, from the stomach to the colon—and an increased risk of developing cancer, including the breast, thyroid, and uterus.
