Ductal Carcinoma in situ in Combination with Inflammatory Breast Syndrome: the Rare Clinical Case

Abstract

Ductal carcinoma in situ (DCIS) is a breast carcinoma (BC) consisting of malignant cells in the ductal lumen of the breast without invasion beyond the epithelial membrane. The article presents a rare clinical case of the combined course of chronic mastitis and ductal carcinoma in situ in a 47-year-old female patient who was diagnosed with chronic mastitis during instrumental examination, and only after trepan biopsy and subsequent histological examination, intraductal breast cancer in situ was verified. This may indicate that instrumental methods and techniques are insufficiently informative in diagnosing ductal carcinoma in situ against the background of chronic mastitis.
