Cowden's disease (CD) and Bannayan-Ruvalcaba-Riley syndrome (BRRS) are allelic disorders characterized by multiple hamartomatous overgrowths of the thyroid, breast, skin, and gastrointestinal tract, and an increased risk of developing benign and malignant tumors of the breast and thyroid gland, secondary to germline point mutations in the PTEN gene. In contrast to thyroid epithelial lesions, abnormalities of the C-cells are currently not considered part of the spectrum of manifestations seen in PTEN-associated syndromes.
