Ectopic gynaecomastia on the inner aspect of the thigh in an otherwise healthy man

Gynaecomastia is a common examination finding in adult men. Supernumery breasts along the milk line are also identified frequently in the adult population. Here we report a case of ectopic gynaecomastia, away from the milk line. A 28-year-old man with no other health problems attended the general surgical clinic with a lump on the inner aspect of his left leg. This was thought to be a lipoma by the referring General Practitioner. It was however noted to have an associated nipple areolar complex and ultrasound confirmed mixed density breast tissue with no evidence of malignancy. Excision was undertaken and histopathology confirmed this to be breast tissue. In this case report, we report the first case of ectopic gynaecomastia in this region in an otherwise healthy man.
