Abstract:Dong Y, Zhou X, Wu B, Wang J, Ma H, Zhou H, Jiang S, Lu G, Hu Q. Four cases of distinctive meningiomas with Zellballen growth pattern. APMIS 2009; 117: 936–40.
Meningiomas are attributed to those tumours with slow-growing pattern occurring predominantly in middle-aged or elderly patients. Fifteen histological variants have been described based on the variable histomorphological features. Herein we report four cases with specific Zellballen growth pattern, giving the tumours a ‘paraganglioma-like’ general aspect. The diagnosis of meningiomas was confirmed by immunohistochemical and ultrastructural findings. Histopathologists should be aware of this specific morphology which can lead to misdiagnosis.
