Benign Breast Cyst in a Young Male

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Benign breast cysts are common in females but exceptionally rare in males.
• Male breast masses often raise concerns for malignancy due to their rarity.

Observation:

• A 37-year-old man presented with a small, tender left breast lump.
• Mammography and ultrasound indicated a simple benign cyst.
• Due to the rarity in males, a biopsy was performed.

Findings:

• Ultrasound-guided core needle biopsy confirmed a benign epithelial cyst lined by foamy cells.
• Pathology findings correlated with radiological assessments.
• This represents the youngest reported male with a benign breast cyst.

Implications:

• This case underscores the need for pathological confirmation of male breast lesions, irrespective of imaging findings.
• Understanding benign breast cyst presentation in males is crucial for accurate diagnosis and management.
• Further research into the incidence and characteristics of benign breast conditions in men is warranted.
