Multiple tuberous xanthomas diagnosed on fine-needle aspiration cytology - Report of a rare case.

ABSTRACT

Xanthomas are papulonodular skin lesions present in lipoprotein metabolism disorders, which result in cholesterol deposits in subcutaneous tissue, tendons, ligaments, periosteum, etc. A 28-year-old male presented with multiple soft-tissue swellings, prominently over joints. Fine-needle aspiration (FNA) from multiple sites had similar appearance with foamy histocytes and giant cells. We describe an unusual case of tendinous and tuberous xanthoma diagnosed by cytology. Acquaintance with FNA cytology findings in xanthomas can help to avoid the need of surgical biopsy, as xanthomas can regress on medical therapy alone.
