AbstractA 31 year old Indian woman presented with bilateral axillary masses that became noticeable with the onset of puberty. The masses exhibited similar consistency to the adjacent normal breast tissue but lacked an associated nipple complex. The clinical impression was lipoma; however, mammography, ultrasonography and skin biopsy revealed ectopic breast tissue. These findings were consistent with the diagnosis of aberrant breast tissue. A subset of ectopic mammary tissue, aberrant breast tissue may constitute a diagnostic challenge and is often misdiagnosed as lipoma, hidradenitis, follicular cyst, or lymphadenopathy. In addition, some studies have suggested that aberrant breast tissue may be at higher risk of malignant degeneration. Therefore, it's important that physicians be familiar with this condition as this may contribute to the early detection of ectopic breast cancer.
