Bleeding diathesis in Noonan syndrome

Abstract

An 18-year-old girl with Noonan syndrome was operated on for prominent ears. Subcutaneous haematomas developed on both sides, and coagulation tests reported a bleeding diathesis. This is seldom mentioned in descriptions of the syndrome, but it has been shown that one-third of all patients with the syndrome have defects in haemostasis. Extended screening is therefore useful.
