Abstract

Pigmented villonodular synovitis (PVNS) is a distinct but rare clinical entity often presents late with a diagnostic difficulty. Its non-specific manifestations require exclusion of several chronic inflammatory disorders and other humorous lesions but all investigations including highly predictive magnetic resonance imaging (MRI) and arthroscopic examination are non-diagnostic demanding confirmatory tissue biopsy. A typical case of such lesion is presented to highlight some potential difficulties.
