Abstract
|
|
|
|
Aberrant breast tissue is a subset of accessory breast tissue, and it exhibits similar consistency to that of the adjacent normal breast tissue, but it lacks an associated nipple complex. It is a developmental anomaly defined as the persistence of breast tissue along the embryonic mammary line. Aberrant breast tissue is most commonly located in the axilla, though it may be present anywhere along the embryonic mammary line. We report here on an 11-year-old girl with aberrant breast tissue and acanthosis nigricans. She had tender masses that became noticeable with the onset of menarche and mottled hyperpigmentation on both axillae. The histopathologic finding of the lesion revealed the typical features of aberrant breast tissue with acanthosis nigricans.
