Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of uncertain etiology that affect synovial lined joints. This disesse is an uncommon that usually afflicts the knee joint. Two types of villi are present in this disease, localized form is called ‘nodular PVNS’ and non localized form is ‘diffuse PVNS’. On microscopy, PVNS is characterized by the presence of hemosiderin-laden, multinucleated, giant cells. But plain radiograph in PVNS shows normal finding exclude effusion, so cannot help diagnosis of PVNS. We experienced a case of a 59-years-old male patient who complained multiple arthralgia, swelling, limit of motion of Lt knee. We gave diagonsis of gout with PVNS by MRI and arthroscopic procedure. So we report this case with review of literature.

Gouty ulcer can be caused by the accumulation of clumps of uric acid in body tissues that lead to acute or chronic inflammation at sites of accumulation. Furthermore, tophi-inhibiting granulation tissue may form a canal that channels microbial infection from the underlying involved joint space, and thus, presents the risk of osteomyelitis development. Accordingly, gouty ulcer must be treated appropriately. In this case, refractory wounds on gouty ulcers at the left shin and left radial ankle were treated by surgical debridement. Negative-pressure wound therapy was used successfully to prevent post-operative delayed wound healing.
