Cellular angiofibroma of the vulva: a clinicopathological study of two cases with documentation of some unusual features and review of the literature.

Background: Cellular angiofibroma (CA) of the vulva is a recently described condition, whose clinical and pathological features are poorly known.

Methods: We have encountered two cases of this very unusual tumor. Their clinical and pathological features were analyzed and compared to those reported in the literature.

Neuroblastoma-like schwannoma: a case report and review of the literature.

We report a case of schwannoma (neurilemmoma) predominantly composed of small cells arranged in rosettes around central collagenous cores and discuss the differential diagnosis of this unusual variant. Schwannoma with giant rosettes, previously designated as neuroblastoma-like schwannoma by Goldblum et al., must be differentiated from neuroblastoma, peripheral neuroectodermal tumors, and malignant change in a schwannoma.
