The Mammary Hamartoma

Abstract

Hamartomas may appear as homogeneously dense, well-circumscribed masses, varying in appearance from the classically described encapsulated mixed fatty-fibroglandular mass. Pathologists can make the diagnosis of hamartoma without the presence of adipose tissue but may have difficulty in distinguishing the hamartoma from fibrocystic change. However, if there is radiologic-pathologic concordance, further surgical excision is not warranted.
