Abstract
A case of Cowden syndrome (CS) is described in a 34-year-old African American female who reported a history of breast and thyroid malignancies. Clinical examination demonstrated multiple soft, white-pink papules across multiple mucosal surfaces of the oral cavity. Microscopy of the lesions revealed hyperkeratotic surface squamous epithelium with papillomatosis and acanthosis along with elongated rete processes. A genomic polymerase chain reaction direct sequencing using the patient's blood was positive for mutations of the PTEN gene typical of CS.
