Cowden's Disease is an autosomal dominant genodermatosis associated with ab
normalities of the breast, thyroid gland, gastrointestinal tract.
We describe a 23-year-old girl who was diagnosed with this disease when she
consulted for evaluation of a multinodular goiter. Further investigations
revealed breast lesions, gastric polyposis and parotid cancer.
Recognizing Cowden's disease is important for prompt screening for malignan
cies. Skin lesions are markers of precancerous development.
