Galactocele of adult male breast: A cytopathologist's perspective

Galactocele, although a common cytological diagnosis in females, is not previously reported as a cause of breast enlargement in adult males. Hyperprolactinemia is the principal cause of galactocele in male breast. Besides drug induced hyperprolactinemia, other anatomical lesions of hypothalamo‐pituitary region and different medical conditions like cirrhosis and chronic kidney disease are to be considered along with a full evaluation of features revealing hypogonadism in case of galactocele. Aspirated milk from the male breast is the primary clue for this detailed investigation process. Here we are presenting the first case of galactocele of the male breast due to hypogonadotropic hypogonadism with idiopathic hyperprolactinemia.
