KROK 1 2020 – Question 133 · KROK (Medicine) · Pathomorphology
A biopsy material obtained from a mammary tumor has solid layers that consist of small epithelial cells with polymorphic nuclei and numerous pathological mitoses. The stroma is scant and has lymphocyte infiltration. Make the diagnosis:
- A. Adenofibroma
- B. Medullary carcinoma
- C. Scirrhous carcinoma
- D. Adenoma
- E. Paget disease
Hint
Judge nuclear atypia and mitotic activity first, then ask what the proportion of tumor cells to stroma and the lymphoid infiltrate suggest about the growth pattern.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
