Gouty tophus presenting as an anterior cruciate ligament mass in the knee: Case report and brief review of relevant literature.

Int J Surg Case Rep 2021 May 27;82:105920. Epub 2021 Apr 27.

Michael Garron Hospital, Toronto, ON, Canada; University of Toronto, Toronto, ON, Canada.

Introduction And Importance: Tophacious gout presenting at the anterior cruciate ligament (ACL) is extremely rare and difficult to differentiate from other intraarticular pathology. This is mainly due to conventional diagnostic tools, such as MRI, producing ambiguous results versus pigmented villonodular synovitis (PVNS) and ganglion cysts.

Case Presentation: Here we report an individual in their late-20s with a gouty tophus located at the origin of the ACL in the knee. Read More

University of Illinois College of Medicine, 1740 W. Taylor St., MC 931, Chicago, IL, 60612, USA.

Diffuse-type tenosynovial giant cell tumor (D-TGCT), otherwise known as pigmented villonodular synovitis, is a locally aggressive tumor which can show multiple recurrences but is rarely associated with metastasis. A handful of studies have elucidated the imaging features and clinical course in metastatic D-TGCT with malignant transformation on histology. However, only 5 cases of metastatic D-TGCT with benign histological features have been reported in the literature, with the clinical course and prognosis reported in only 1 case. Read More

Department of Orthopaedic Surgery, The Orthopaedic Speciality Clinic, Pune.

Pigmented villonodular synovitis (PVNS) is a rare benign condition that is locally aggressive and may destructively invade the surrounding soft tissues and bone causing functional loss of the joint and the limb. The knee is the most affected joint (range, 28% to 70%) but involvement of the bone is not a common feature seen at this site. We present a rare case of diffuse PVNS of the knee associated with subchondral cyst of the lateral femoral condyle. Read More

Human Anatomy Department, Medical University of Lublin; Radiology Department, St Johns' Cancer Center; Lublin, Poland.

Pigmented villonodular synovitis (PVNS) is a benign disease that rarely undergoes malignant transformation. There are two types of disease: localized (nodular tenosynovitis) and di used (pigmented villonodular synovitis/tenosynovitis) with intra- or extra-articular locations.
