Myxomas of the ear are extremely uncommon, especially in young children. A 23-month-old girl born to a family with known Carney complex, a condition that predisposes to multiple myxomas, presented with a large, cauliflower-like mass located on the back of her right ear. Histopathologically, the lesion was composed of scattered spindle-shaped or stellate cells with abundant associated mucin and a very sparse inflammatory infiltrate containing lymphocytes and neutrophils. The patient was a carrier of a protein kinase A regulatory subunit 1A (PRKAR1A) mutation; PRKAR1A mutations cause Carney complex in most patients with this rare disorder. This is the earliest presentation of an ear lobe myxoma reported in the literature.
