KROK 1 2020 – Question 9 · KROK (Medicine) · Pathomorphology
When examining a biopsy material obtained from the thyroid gland, the pathologist discovered lymphocyte infiltration of the thyroid tissues and destruction of the parenchymal elements. Diffuse lymphocyte infiltration with lymphoid follicles was detected in the stroma. What is the most likely diagnosis?
- A. Hashimoto’s thyroiditis (chronic lymphocytic thyroiditis)
- B. Papillary thyroid cancer
- C. Solid adenoma of the thyroid
- D. Graves’ disease (toxic diffuse goiter)
- E. Undifferentiated thyroid carcinoma
Hint
Consider what a stroma full of lymphoid follicles with progressive loss of the parenchyma says about the type of process, as opposed to a process that adds new cells.
