Sipple syndrome and pregnancy.

Sipple syndrome is an unusual entity during pregnancy. To our knowledge, this is the second case report of a pregnant patient with signs of Sipple syndrome. During pregnancy, this syndrome may present unusual complications, which require informed physician expertise for appropriate management. Our patient had a strong family history for Sipple syndrome, which is considered to be transmitted as an autosomal dominant. Thus, other family members, including the patient's offspring must be assessed frequently during their lifetime for any of the developing manifestations of this entity. Genetic counseling should be included in the management of all patients with Sipple syndrome.
