Hamartoma of the breast in a man

Abstract

Rationale: Mammary hamartoma is a rare benign breast tumor, composed of ducts, lobules, fibers, and adipose tissue. We describe a mammary hamartoma in a man; this is the fourth case being reported in the literature.Patient concerns: A 30-year-old man presented with a 1-month history of a painless mass in his right breast.Diagnosis: Ultrasound imaging and mammography revealed a lesion, approximately 2.0 cm  2.0 cm in size, in the right breast, which was considered to be either a lipomyoma or an adenoma fibrosum.Interventions: The mass was surgically resected. Pathological examination confirmed the diagnosis of mammary hamartoma.Outcomes: The patient was discharged from the hospital after surgery. There was no sign of reoccurrence during a 1-year followup period.Lessons: At present, mammary hamartoma is considered to be a benign lesion, usually treated by surgical resection. Some reports have suggested a possible association between a hamartoma and the development of breast malignancy. The pathology and biology of an association between a mammary hamartoma and malignancy have not been defined to date.Abbreviations: T1W1 = T1-weighted magnetic resonance images, US = ultrasonography.

Breast hamartoma: A case series of 4 hamartoma cases including a rare myoid hamartoma of male breast

“…First case was 36-year man, second was a 13-year-old boy, third was 30-year-old man, fourth was a 41-year-old man. [10][11][12] The probable reason for rarity of this lesion in males is under-reporting of cases as most of the cases are over looked as gynecomastia.…”
