[Cowden syndrome]
Introduction:
Cowden syndrome is rare; oral symptoms are not always diagnosed. This case of Cowden syndrome was revealed by gingival hypertrophy.
Observation:
A 21-year-old female patient consulted for gingival hypertrophy and multiple papules in the mouth. She had a history of thyroid lobectomy due to a goiter. The gingival papillomatosis and the goiter suggested a Cowden syndrome. The diagnosis was confirmed clinically by facial skin papules.
Discussion:
Cutaneous and oral lesions are usually the first symptoms of the syndrome. Diffuse gingival papillomatosis may suggest a Cowden syndrome and should lead to screen for associated symptoms. A high-risk diagnosis of breast and thyroid cancer is associated to Cowden syndrome and the patient should have a yearly follow-up.
