  • Pigmented villonodular synovitis(PVNS) is a benign proliferative lesion, involving synovial tissue in joints, tendon sheaths, and bursae. Pigmented villonodular synovitis is a rare and usually monoarticular condition and primarily affects the knee joint and hand. Polyarticular PVNS appears in less than 1% of all case and its occurrence in the shoulder is rare(<2%). We present a 64-year-old male who had pigmented villonodular synovitis of both shoulder joints, which was treated by arthroscopic total synovectomy.

  • Localized nodular synovitis of the knee joint is a rare benign tumorous condition, and should be differentially diagnosed with pigmented villonodular synovitis. We report a case of localized nodular synovitis in the knee that was noted to have a pedicle and characteristic findings on MR image.

  • The authors reviewed and analyzed the pathologically confirmed 230 cases of benign soft tissue tumors which had been treated at Department of Orthopaedic Surgery in Seoul Hospital, Hanyang University College of Medicine from February 1984 to November 1997. The following results were obtained. 1. The most common benign soft tissue tumors was ganglion(26.5%) followed by hemangioma(19.6%), lipoma(17.0%), Baker's cyst(13.0%) and neurilemmoma(7.0%) in decreasing order of incidence. 2. Benign soft tissue tumors were found evenly distributed over all age group. Hemangioma and lymphangioma were usually found to occur before 20 years old. 3. Female was affected about 1.3 times more common. But, Baker's cyst and neurilemmoma occurred most frequently in male. 4. In children, the most common benign soft tissue tumors was hemangioma followed by ganglion, lymphangioma, and lipoma. In adult, ganglion, lipoma, Baker's cyst, hemangioma were common. 5. The lower extremity was the predominant site of occurrence(60.0%). 6. Benign soft tissue tumors were taken by excision. Local recurrences were developed in 22(9.6%) out of 230 cases, especially in hemangioma.

  • The occurrence of PVNS in the TMJ is very rare. We report a case of PVNS which was misdiagnosed as a parotid tumor at first. CT and conventional radiograph revealed a well defined mass demonstrating higher attenuation than adjacent soft tissue. Erosion and expansion of the cortical plate of the mandibular condyle and sclerotic change beneath the margin of the lesion were also shown. MRI demonstrated well defined mass of very low signal intensity on both Tl and T2-weighted images due to ferromagnetic effect of the high concentrated hemosiderin and clearly delineated the extent of the lesion. Histopathologic findings and characteristic appearance of the various imaging methods were described and the usefulness of these images for diagnosis and pretreatment evaluation of PVNS were also discussed.
