An unusual case of bilateral galactocoele in a male infant

摘要

A galactocoele is a rare, benign, milk-filled cystic lesion. It is usually unilateral although bilateral cases have been reported. The aetiology is unknown but it has been suggested that it may be associated with previous or present stimulation by prolactin, some form of ductal obstruction or the presence of secretary breast epithelium. Previous case reports have included a male infant with persistent hyperprolactinaemia and another with panhypopituitarism. In our case, the hyperprolactinanemia was transient. Surgical excision is curative.4 Paediatricians need to be aware of galactocoele as a differential diagnosis of breast enlargement in infants.
