Eyelid nodules were investigated in a patient with Carney complex who was heterozygous for the most commonly known PRKAR1A-inactivating mutation, c.578delTG. Immunohistochemical studies confirmed the diagnosis of myxoma. Loss of heterozygosity was not present, suggesting that haploinsufficiency alone was responsible for tumorigenesis of this eyelid lesion.
