© 2018 Walter de Gruyter GmbH, Berlin/Boston.Bannayan Riley Ruvalcaba syndrome (BRRS) is exceedingly rare, with only about 50 reported cases to date. We report a patient with hypoglycemia, precocious puberty and diffuse testicular microlithiasis accompanying BRRS, and think that this case is important in the light of a newly identified mutation in the PTEN gene. Close attention must be paid in terms of PTEN mutations in cases of macrocephaly and accompanying neurological and dermatological findings.
