Bannayan-Riley-Ruvalcaba syndrome is a rare condition caused by mutation in the PTEN gene. It can cause pigmentation defects, hamartoma and behavioural abnormalities. We report the case of a 10-year-old boy with short stature, pigmented maculae on the glans penis, obsessive-compulsive disorder and macrocephaly. The case is presented due to the rarity of the condition and its predisposition to tumour formation.
