KROK 1 2019 – Question 106 · KROK (Medicine) · Pathomorphology

A 27-year-old woman has undergone a sector resection of mammary gland tissue. Macroscopy detects a dense white node, 4 cm in diameter, with clear margins in the excised tissue. Immediate histological analysis shows the tumor to consist of a large amount of fibrous stroma with stromal proliferation around the small canaliculi. Canalicular epithelium overlays the basement membrane and retains its polarity. Make the diagnosis:

  1. A. Adenocarcinoma
  2. B. Pericanalicular fibroadenoma
  3. C. Sarcoma
  4. D. Cancer
  5. E. Dyshormonal disorders
Hint

Use the sharp margins, the retained polarity of the epithelium on its basement membrane and the dominant fibrous component to decide what kind of breast lesion this is.
