A 54-year-old woman presents with a two-month history of an intermittent dark discharge from her right nipple. She has no other breast symptoms. Examination is normal apart from the production of a small volume of dark brown discharge from a single duct as illustrated when the area around the lateral aspect of the nipple is pressed. Microscopy of the discharge shows haemosiderin-containing macrophages and red blood cells. Which one of the following is the most likely diagnosis?
(A) Benign duct papilloma
(B) Intraductal carcinoma-in-situ (DCIS)
(C) Mammary duct ectasia
(D) Paget disease
(E) Mondor disease
