A Male Patient With Breast Hamartoma: An Uncommon Finding

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Mammary hamartoma is a rare benign breast tumor comprising normal mammary tissue elements.
• Male breast tumors are often misdiagnosed as gynecomastia, leading to under-reporting of conditions like mammary hamartoma.
• Fewer than five case reports of male breast hamartoma exist in current literature.

Observation:

• This report details a rare case of an enlarging mammary hamartoma in a male patient.
• The case highlights the diagnostic challenges posed by the uncommon clinical presentation and lack of definitive radiologic and pathologic characteristics.
• The patient presented with a palpable breast mass.

Findings:

• Pathohistological examination confirmed the diagnosis of mammary hamartoma.
• Imaging features, though not definitively characteristic, were analyzed.
• The benign nature of the tumor with an excellent prognosis was established.

Implications:

• Increased awareness of mammary hamartoma in men is crucial for accurate diagnosis.
• This case underscores the importance of comprehensive evaluation for male breast masses, beyond common diagnoses like gynecomastia.
• Further research into the specific imaging and pathological markers for male mammary hamartoma could improve diagnostic accuracy.
