Fibroadenoma in axillary ectopic breast

Area of Science:

• Surgical Pathology
• Dermatology
• Oncology

Background:

• Axillary lumps are common, presenting diverse differential diagnoses in surgical practice.
• An unusual isolated axillary mass was identified in a young female patient.

Observation:

• The patient presented with a 2-year history of right axillary swelling, measuring 3 cm ×3 cm.
• The mass was mobile, non-tender, with no associated breast lump or skin changes.
• Initial workup for lymphadenopathy, including tuberculosis, was negative.

Findings:

• Ultrasound revealed a well-circumscribed oval lesion.
• Fine needle aspiration suggested benign proliferative breast tissue.
• Histopathological assessment confirmed fibroadenoma within ectopic breast tissue.

Implications:

• This case underscores the importance of considering ectopic breast tissue in the differential diagnosis of axillary masses.
• Fibroadenoma in ectopic breast tissue is a rare but important consideration for clinicians.
• Accurate diagnosis and management of axillary lumps require comprehensive evaluation.
