Hemangioma are not rare tumors. They can be found in almost any of the vascular structures of the body. Hemangiomas involving the deep structures of the extremities may produce extremely difficult therapeutic problems for the orthopedic surgeon. Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. We have experienced a patient who has of foot and report an optimal method of surgical treatment. Authors report the result of hemangioma in mid-foot which arise from removal of a pigmented villonodular synovitis that has low out break rate of benign tumor in mid-foot with literature review.

Pigmented villonodular synovitis (PVNS) is a slowly, progressive, proliferative disorder of synovial tissue characterized by villous or nodular changes of synovial-lined joints, bursae, and tendon sheaths and most frequently affects the large joints, with the knee and hip. A few studies have been reported that occurred PVNS in small joint, but mainly in hands. It is a very rare condition that occurs in the small joints of the forefoot. We have experienced the case, which developed in small joint of the forefoot, and performed total synovectomy. After the operation, there was no recurrence. We report a case of PVNS in forefoot with a review of the literature.

Most pigmented villonodular synovitis (PVNS) is occurred in knee joint and finger of hand. PVNS is rarely occurred in shoulder joint. In English and French literatures, less than 30 cases were reported. We report 3 PVNS cases with rotator cuff tears, which was treated by arthroscoic extensive synovectomy, debridement and rotator cuff repair. The PVNS with rotator cuff tear in shoulder joint was rarely reported in the Korean literature.

Sarcoidosis is a multi systemic granulomatous disease of unknown etiology and pathogenesis. The granulomas are non-caseating, and the organs that are affected most frequently are the lungs, the skin, and the eyes. However it may also involve the liver, spleen, bone, nervous system, and other organs. The diagnosis is based on the identification of noncaseating granuloma in the tissues involved, excluding other granulomatous conditions. The diagnosis of sarcoid joint disease is often made in retrospect and only when the lung or eye is involved. We report a case of sarcoid synovitis in knee joint with review of literature.

Musculoskeletal ultrasound has unique advantages that may be free from exposure to radiation, low price compared to MRI, outpatient procedure that can be easily accessible, and better accuracy combined with physical examination. Dynamic ultrasound performed with stress tests are known to be useful for detecting the hidden lesions in the tendons, ligaments, nerves. Ultrasound in the elbow can be used easily in the outpatient for evaluation of the joint surface and synovial space; diagnosis for tendon diseases such as lateral epicondylitis, medial epicondylitis and morbidity of peripheral nerves; guide for anterior-posterior bursal and intra-articular injections.

Pigmented villonodular synovitis (PVNS) is a proliferative disease that affects the synovial joint, tendon and bursa. PVNS can form a nodular structure in any joint, but it most commonly affects the knee joint and is rare in the foot and ankle joint. PVNS is divided into two types. Localized-type PVNS exhibits focal involvement with a nodular mass, while diffuse-type PVNS involves the entire synovium. Synovitis of the affected joint can also destroy cartilage and bone. Diffuse type accounts for 75% of PVNS and has a reported recurrence rate of 12.2% to 46%; aggressive synovectomy is recommended as the most effective treatment. In localized-type PVNS, only arthroscopic partial synovectomy is effective with a lower recurrence rate. We report a patient with severe ankle joint arthritis induced by diffusetype PVNS. The patient was treated by lateral malleolar ostectomy and ankle arthrodesis with a plate and screws via a lateral approach.

Temporomandibular joint cysts usually occur between the second and fourth decade of life. There is a female predominance to male of approximately 3 to 1. The patients complain of swelling, pain and sometimes decreased mouth opening. Synovial cysts of the temporomandibular joint seem to develop by an increase of intraarticular pressure due to trauma or inflammation which causes capsular herniation. However, if inflammatory synovial cysts develop by an increase of synovial fluid into inflammation tissue in the capsule without capsular herniation, a differential diagnosis should include synovial chondromatosis and synovitis. This is a case report of a synovial cyst developed in a capsule of the temporomandibular joint.

We experienced a patient(53-year-old female) with knee joint effusion, pain and stiffness who had not responded to steroid injection therapy, significantly improved by bee venom acupuncture in clinical symptom. And for a opinion that prohibited bee venom acupuncture on DM because of increasing serum glucose level by increasing serum cortisol level, we also experienced that serum glucose level of DM patient stabilized by bee Venom acupuncture treatments, so we report this case with literature review of articles.

To investigate the morphology of the synovial lining cells, synovitis was induced by carrageenin injection into the rat knee joint cavities. Synovial membranes were excised at 1, 3, 5, 7 and 14 days, and histologic, electron microscopic, histochemical (periodic acid Schiff: PAS, toluidine blue), and enzyme histochemical (acid phosphatase: ACP, nonspecific esterase: NSE and endogenous peroxidase) studies were performed. The results are as follows: Carrageenin induced synovial membrane hypertrophy with synovial cell proliferation and granuloma formation. The proliferated synovial lining cells and macrophages in the granulomatous lesion had round to oval nuclei and large, plump cytoplasm with many phagocytotic materials and vacuoles. Electron microscopically, these cells had small number of granular endoplasmic reticulum and many lysosomes, phagosomes and vaculoes. Mitotic figures were observed at early stage of experiment. PAS and toluidine blue stains showed strongly positive reaction in the cytoplasm of the proliferated lining cells and macrophages in granulomatous lesion. ACP and NSE activities were strong positive in the cytoplasm of the proliferated synovial lining cells and macrophages in the granulomatous lesion. But endogenous peroxidase stains were negative in all prolifeative lining cells and macrophages in granulomatous lesion. Conclusively, carrageenin-induced synovitis showed proliferation of synovial lining cells and granuloma formation in deep layer. The macrophages, which consisted of the lesions and have active phagocytic function, were speculated to proliferate by mitosis of superficial synovial A cells and histiocytes in the deep layer of the synovial membrane.

The development of synovial membrane from knee joint was studied by electron microscope in human fetuses ranging from 20mm to 260mm crown rump length (40days to 30weeks of gestational age). At 40mm fetus, developing synovial tissue was observed in homogenous interzone as a vascular mesenchyme around the periphery. The primitive joint space was appeared after the intermediate layer of the interzone in direct contact with chondrogenic layer at 60mm fetus. Differentiation of the synovial membrane coincided with clarification of the joint cauity. When dilatation of the synovial cavity occurred, the two types of synovial cells were well endowed with rough endoplasmic reticulum. At 100mm fetus, type A cells with a markedly attenuated cytoplasm were found as well as those cells which contained pinocytotic vesicles and vacuoles. By 150-200mm fetuses a majority of the intimal cells were type B. These cells were characterized by abundant rough endoplasmic reticulum and well developed Golgi complex. In contrast, A-type cell had numerous filopodia, pinocytotic vesicles lysosomes, and large vacuoles containing amorphous material. At 260mm fetus, the intimal cells were well developed and plentiful. The most marked difference between the synovial membrane of full-term fetus and adult was the large amount of collagen in the latter. During fetal period, the B-cells were most numerous cell type in the intimal cells. The B-cells were clearly distinguishable from the A-cells by their content of extensive rough endoplasmic reticulum and well developed Golgi complex.
