Fine needle aspiration of angiomatoid malignant fibrous histiocytoma - A case report

BACKGROUND: During recent years, reliable cytodiagnostic criteria have been proposed for a number of soft tissue lesions, both benign and malignant. H owever, cytomorphologic descriptions of angiomatoid malignant fibrous histi ocytoma (AMFH) me locking. We report the cytomorphologic features of this u ncommon lesion. CASE: A 10-year-old female presented with a swelling in the thigh that, on fine needle aspiration (FNA), tons reported as a soft tissue tumor ( vasofo rmative) of intermediate malignancy. Subsequent excision with histopatholog ic examination confirmed the diagnosis. CONCLUSION: The differential diagnosis of AMFH based on FNA findings call b e difficult and should be made in conjunction with clinical findings.
