Abstract

Cowden's disease is a rare autosomal dominant, multiple hamartoma syndrome with characteristic mucocutaneous lesions. It is associated with abnormalities of the breast, thyroid, and gastrointestinal tract; and is characterized by multiple hamartomas in the gastrointestinal tract and mucocutaneous lesions such as trichilemmomas, oral papillomatosis, facial papules, and acral keratosis. A 21-year-old male patient presented with erythematous facial papules, oral mucosal papillomatosis, and punctate palmoplantar hyperkeratosis indicating a definite case of Cowden's disease. This disease derives from variable expression resulting from a mutation in the PTEN gene. Gastrointestinal endoscopy and colonoscopy revealed multiple hamartomas in the stomach and colon. On thyroid ultrasonography, several probable benign nodules were noted in the right thyroid gland. He had no pertinent family history and no other systemic findings. Further regular laboratory and image studies will be planned for our patient, as well as his family members. Sporadic Cowden's disease is rarely observed. Herein, we report a case of Cowden's disease without known family history. Dermatologists should be aware of the possibility of Cowden syndrome based on its several dermatologic findings.
