title: A painful perineal lump: an unusual case of ectopic breast tissue.
abstract: We report the case of a 40-year-old lady who presented with an episodically painful perineal lump. Clinical and radiological investigations were inconclusive. Excision biopsy confirmed an ectopic breast mass. Ectopic breast tissue is difficult to diagnose but close attention to clinical  findings can help to guide further investigation and diagnosis.
