Bannayan–Riley–Ruvalcaba syndrome (BRRS) is a rare hamartomatous disorder with occurrence of multiple subcutaneous lipomas, macrocephaly and hemangiomas.[1][2] The disease is inherited in an autosomal dominant form, but sporadic cases have been reported. The disease belongs to a family of hamartomatous polyposis syndromes, which also includes Peutz-Jeghers syndrome, juvenile polyposis and Cowden syndrome. Mutation of the PTEN gene underlies this syndrome, as well as Cowden syndrome, Proteus syndrome, and Proteus-like syndrome. Collectively, these four syndromes are referred to as PTEN Hamartoma-Tumor Syndromes (PHTS).

Presentation

Most lesions are slowly growing and easily resectable. Visceral as well as intracranial involvement may occur in rare cases, and can cause bleeding and symptomatic mechanical compression, especially of the spinal cord or spinal nerve roots. This may require surgical resection.

The macroencephaly is symmetrical, and does not cause widening of the ventricles or raised ICP (intracerebral pressure).

Etymology

The syndrome combines Bannayan-Zonana syndrome, Riley-Smith syndrome, and Ruvalcaba-Myrhe-Smith syndrome.[3] Bannayan-Zonana syndrome is named for George A. Bannayan and Jonathan Zonana.[4][5][6] Riley-Smith syndrome was named for Harris D. Riley, Jr. and William R. Smith.[7] Ruvalcaba-Myrhe-Smith syndrome is named for S. Myhre, Rogelio H. A. Ruvalcaba and David Weyhe Smith.[8]
