Summary
Background
Accessory breast tissue can be present anywhere in the milk ridge because of incomplete involution. However, lactating accessory breast in the groin is rare.
Methods
Case report.
Results
We report a 36-year-old para 2, gravid 2, woman presenting with lactating accessory breast in the groin. She had similar symptoms during breastfeeding her first child but the symptoms subsided after she stopped breastfeeding only to recur during nursing her second child born 5 years after. Biochemical testing of the secretion confirmed it as milk. Aspiration cytology by fine needle of the swelling confirmed the breast tissue. She had no urogenital anomaly. Excision of the accessory tissue gave her relief.
Conclusions
Awareness of this rare but interesting abnormality in embryological development is important. One should look for the associated abnormalities. If conservative measures fail, excision is the treatment of choice.
