KROK 1 2008 – Question 175 · KROK (Medicine) · Pathomorphology
Examination of a young woman revealed a node-like, soft and elastic homogenous tumour of pinkish-white colour along the acoustic nerve. The tumour contains cell bundles with oval nuclei.

What tumour is it?
- A. Neurinoma
- B. Ganglioneuroblastoma
- C. Ganglioneurinoma
- D. Malignant neurinoma
- E. Neuroblastoma
Hint
Think about the likely cell of origin of a tumour along a cranial nerve and what palisaded nuclear rows separated by cell-free zones indicate.
