KROK 1 2018 – Question 153 · KROK (Medicine) · Pathomorphology
A young woman presents with a tumor along the auditory nerve. The tumor is node-shaped, 3 cm in diameter, soft and elastic, pink-white colored, and has homogeneous structure. Microscopically the tumor contains bundles of cells with oval nuclei. These cellular fibrous bundles form regular structures made up of parallel rows of regularly oriented cells arranged in the form of a palisade with acellular homogeneous area in between (Verocay bodies). Name this type of tumor:
- A. Neuroblastoma
- B. Neurinoma
- C. Ganglioneuroma
- D. Malignant neurinoma
- E. Ganglioneuroblastoma
Hint
Consider the tumor's location along a cranial nerve, its soft, well-defined gross appearance, and what palisaded rows of cells around acellular zones suggest about the cell of origin.
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.
