    Abstract:
    Hemangiopericytomas (HPCs) are tumors, constituting 2.5%, of soft tissue neoplasms. Meningeal hemangiopericytomas are rare non meningothelial mesenchymal tumors of the dura. They were classified as angioblastic meningiomas because of their similarity to meningiomas. However, these tumors are now regarded as distinct entities, akin to hemangiopericytoma elsewhere in the body. Few reports have addressed the fine needle aspiration (FNA) cytology of HPC. We present the cytological findings of one such rare case ofprimary meningeal hemangiopericytoma which metastasized to the lymph node. A 47 years male presented with cervical lymphadenopathy of 2 months duration. He was operated twice in the last 4 years and diagnosed atypical meningioma both times. The patient now also had spinal metastasis producing nerve root compression. Aspiration cytology of the node revealed cellular aspirate demonstrating round to oval cells with ample cytoplasm, round nuclei and inconspicuous nuclei. They showed a characteristic ferning out of blood vessels. Occasional mitosis was present. A diagnosis of malignant tumor of vascular origin was offered. Lymph node biopsy showed a characteristic histological picture of hemangiopericytoma described in other soft tissues. The cytology of this tumor is characteristic, but the rarity of the lesion, especially in metastatic sites makes diagnosis difficult unless a high index of suspicion is present. The recognition of the distinct cytological findings makes this possible. The case documents the role of FNA cytology in confirming HPC.
