Pigmented Villonodular Synovitis (PVNS) is a unique benign proliferative process of unknown aetiology involving the synovial lined joints diffusely or focally. The entity remains a diagnostic challenge. This condition is attributed to an increased synovial proliferation causing villous or nodular changes of synovial lined joints leading to PVNS, Pigmented Villonodular Bursitis (PVNB) when arising from bursae or Pigmented Villonodular Tenosynovitis (PVNTS) originating from the tendon sheath. We present a case of a young female with nodular masses on right thumb with cytomorphological features on FNAC suggestive of PVNS which was finally confirmed by histopathology.
