Extra-osseous tenosynovial chondromatosis of the middle finger: a case report.
(26/32)
Extra-osseous tenosynovial chondromatosis is rare and has a high rate of local recurrence. We report a 23-year-old man who presented with a 6-month history of pain and swelling of the right middle finger and painful limitation of the ring finger flexion secondary to this condition. Surgical exploration revealed multiple loose bodies of varying size arising from the flexor tendon sheath. Histopathological examination revealed mature chondroid tissue and focal calcification. After 2 years of follow-up, the patient had achieved an excellent functional recovery and showed no evidence of recurrence. (+info)

Synovial osteochondromatosis of the hip with femoroacetabular impingement and osteoarthritis: a case report.
(28/32)
Synovial osteochondromatosis is a rare, benign condition characterised by synovial metaplasia and the formation of cartilaginous and osteocartilaginous bodies in the capsule. We report one such case in a 30-year-old woman with synovial osteochondromatosis of the hip and progressive osteoarthritis caused by femoroacetabular impingement with joint-space narrowing. She underwent surgical removal of 32 loose bodies and osteochondroplasty. A coronal osteophyte at the junction of the femoral head and neck was also excised. At 2-year follow-up, her Harris Hip Score had improved from 62 to 90. (+info)

Chromosome rearrangements in synovial chondromatous lesions.
(30/32)
Short-term cultures from one synovial chondroma and three cases of synovial chondromatosis, a lesion for which no previous karyotypic information exists, were cytogenetically analysed. Whereas the chondroma displayed the relatively simple karyotype 46,XY,add(12)(q13),der(17)t(12;17)(q13;q21), more complex changes were found in the three cases of chondromatosis: case 1, 47,XY,der(1)inv(1)(p13q25)del (1)(q25q32), t(1;12)(q25;q13), + 5,der(12)add(12)(p11)t(1;12)(p22;q13); case 2, 47,XY,add(10)(q26), + 20/46 idem,-6/46,XY,t(2;4)(q33;q21), add(21)(p11); and case 3, 44,XY,add(1)(p36), del(1)(p13p22),add(6)(p25), del(7) (q22q32),del(10)(q21),add(11)(q13),-17,-18. The cytogenetic findings strongly suggest that synovial chondro-matosis is a clonal proliferation. Apart from a near-diploid chromosome number, the only recurrent cytogenetic features among the four cases were loss of band 10q26 and rearrangements of 1p13 and 12q13, found in two cases each. While chromosome bands 1p13 and 10q26 have not been reported to be involved in other types of benign chondromatous lesions, the 12q13-15 segment is recurrently rearranged in a variety of chondromatous tumours, e.g. pulmonary chondroid hamartomas. The present finding of translocations affecting band 12q13 in two of the cases emphasises that, irrespective of the anatomical localisation of the tumours, rearrangements of genes in 12q13-15 are important in the development of a large subset of benign and malignant cartilage-forming tumours.

Synovial chondromatosis of the metacarpophalangeal joint: case report and review of the literature.
(31/32)
Intra-articular synovial chondromatosis in the hand is rare but should be considered in the differential diagnosis of a swollen, stiff or painful joint. Other possible diagnoses include osteoarthritis, rheumatoid arthritis, gout, trauma and chronic infection, and unless enchondral ossification of loose bodies is seen the diagnosis of synovial chondromatosis may not be made preoperatively. A 69-year-old man with synovial chondromatosis of the metacarpophalangeal joint is reported. The joint was swollen and tender. He had not sustained trauma and there was no evidence of arthritis, involvement of other joints or infection. Complete synovectomy with removal of all loose bodies was successful and his symptoms resolved. Intra-articular synovial chondromatosis is a benign condition, but spontaneous resolution is the exception and surgical synovectomy remains the most effective treatment. (+info)
Primary synovial chondromatosis--a case report.
(32/32)
Synovial chondromatosis are rare tumours encountered in hip, knee and shoulder joints. Synovial chondromatosis at metatarso-phalangeal joints are still rarer. Herein is reported a case of primary synovial chondromatosis of metatarsophalangeal joint in 54-year-old male. A brief review of previous published articles has been dealt herewith. (+info)
