Abstract
BACKGROUND: Hemangiopericytomas (HPCs) are rare spindle cell tumors, constituting 2.5% of soft tissue neoplasms. Few reports have addressed the fine needle aspiration (FNA) cytology of HPC. CASE: We describe the FNA biopsy (FNAB) findings in a 44-year-old patient with a previously resected meningeal hemangiopericytoma. The patient underwent ultrasound-guided FNAB of a 16.0-cm, radiographically heterogeneous density in the liver. The FNA smear showed crowded, ovoid to spindle-shaped cells with poorly defined, scant cytoplasm. The neoplastic cells were positive for CD34 and negative for CD31, factor VIII, glial fibrillary acid protein and cytokeratin AE1/AE3, supporting a diagnosis of HPC and compatible with metastasis from the patient's cerebral tumor. CONCLUSION: This case documents the role of FNA cytology in confirming HPC.
