Fine-needle aspiration biopsy of metastatic soft-tissue sarcomas to lymph nodes.

This paper highlights the role of fine-needle aspiration cytology (FNAC) in 15 cases of metastatic soft-tissue sarcomas involving lymph nodes. Histopathology reports of the primary tumor were available in all cases. Histological diagnoses correlated well with the cytology reports. The most common type of sarcoma to involve the lymph node was embryonal rhabdomyosarcoma (6 cases), followed by synovial sarcoma (2 cases), leiomyosarcoma (2 cases), malignant fibrous histiocytoma (2 cases), fibrosarcoma (1 case), malignant peripheral nerve sheath tumor (1 case), and rhabdomyosarcoma (1 case). FNAC was thus helpful in the early diagnosis, proper staging, and management. Importantly, it obviated a lymph node biopsy in the majority of cases.
