Abstract

Pigmented villonodular synovitis (PVNS) is a rare benign neoplasm involving the synovial joints and tendon sheaths. It can be classified into localised and diffuse type. The diffuse type of PVNS is larger and very aggressive, clinically mimicking as soft tissue sarcoma. Radiological investigation can aid in knowing the relation of the mass to the joint cavity and invasion of surrounding structures. A biopsy can pose a diagnostic challenge for pathologists. Surgical excision is the treatment of choice. Histopathological examination is necessary for a definite diagnosis.

Keywords: Pigmented villonodular synovitis; diffuse; soft tissue sarcoma; histopathology.
