BACKGROUND: The differential diagnosis of destructive lytic lesions of the spine includes amyloid tumors. The diagnosis of amyloid tumor with fine needle aspiration biopsy (FNA) is challenging. Previous reports of FNA of osseous amyloid tumors have detailed the cytologic appearance of amyloid along with lymphocytes, plasma cells and histiocytes, occasionally multinucleate or forming granulomatous lesions. CASE: An 84-year-old man presented with neck pain. Radiologic studies showed a destructive, lytic lesion of C-6, with a large, soft tissue mass. FNA yielded many acellular smears containing abundant amyloid that was confirmed with special stains of corresponding tissue cores and subsequent surgical biopsies. CONCLUSION: Osseous amyloid tumors are destructive, lytic lesions that mimic other processes. Amyloid can be distinguished from other substances in FNA samples and amyloid tumor identified, even when amyloid is present without typical cellular components.
