[A Case of Paget-Type Recurrence 20 Years after Breast Conserving Surgery for Invasive Ductal Carcinoma].

We report an 85-year-old female suffered Paget-type recurrence at right remnant breast. The patient had undergone breast conserving surgery(BCS)20 years ago in another hospital for invasive ductal carcinoma of the right breast(pT1N0M0, Stage I ). Her chief complain was a skin ulcer of the right nipple. The pathological diagnosis for biopsy specimen from the areola was Paget's disease. She underwent total mastectomy. Paget cells were detected pathologically in the epidermis of the nipple and nearby mammary duct connected with fibrous tissue after BCS, suggesting Paget-type recurrence of invasive breast carcinoma.
