Fine needle aspiration cytology of malignant endovascular papillary angioendothelioma.

Here we described a rare case of malignant endovascular papillary angioendothelioma (Dabska tumor) in an adult female. On fine needle aspiration, the smear showed many small clusters of tumor cells with rosettoid arrangement along with papillary fragments with fibrovascular core and hobnail like arrangement of the cells. Histopathological examination revealed a vascular tumor in the form of papillary projection into the vascular lumina, lined by atypical endothelial cells.
