2/112. Evanescent exostosis. A new case.Much has been written about the natural history of osteochondromas, but there are only a few reports in the literature reflecting the spontaneous disappearance of this lesion. For that reason, we report an additional case which makes the total number of reported cases eleven, and also includes a review of the literature.- - - - - - - - - - ranking = 6.6101851012467keywords = exostosis, osteochondromas (Clic here for more details about this article) |
3/112. Osteolipoma of the hand: a case report.A 61-year-old, healthy woman presented with a six-month history of a mass on the radial volar aspect of her dominant right hand. The patient had a history of trauma to the hand six years previously. Radiographs showed a bony lesion in the index metacarpal shaft and the MRI showed a bony lesion and soft tissue mass suggestive of a parosteal lipoma. Surgical excision of the lesion revealed a lipoma overlying a bony exostosis or osteolipoma of the hand. Post-operatively, the patient's symptoms resolved and she had no recurrence of the tumor.- - - - - - - - - - ranking = 1.4025462753117keywords = exostosis (Clic here for more details about this article) |
4/112. Isolated musculocutaneous neuropathy caused by a proximal humeral exostosis.We report an isolated musculocutaneous neuropathy caused by a proximal humeral osteochondroma that became symptomatic after the patient played recreational basketball. Lesion resection resulted in complete deficit resolution. Mass lesions involving the musculocutaneous nerve should be considered in patients with atraumatic, isolated musculocutaneous neuropathies that are recurrent or fail to recover, even in the setting of strenuous exercise.- - - - - - - - - - ranking = 5.6101851012467keywords = exostosis (Clic here for more details about this article) |
5/112. Metadiaphyseal chondroblastoma of the thumb.chondroblastoma is typically located in the epiphysis. Predominant metadiaphyseal location is very rare, as is involvement of the digits. We describe a case of chondroblastoma involving the metadiaphysis of the thumb. The patient was a 13-year-old boy who presented with pain and swelling of his left thumb. Radiographs showed an expanded lytic lesion involving the whole metaphysis and diaphysis of the proximal phalanx, which subsequently progressed to involve the epiphysis. curettage and bone grafting were done.- - - - - - - - - - ranking = 0.070558088499336keywords = diaphyseal (Clic here for more details about this article) |
6/112. Bizarre parosteal osteochondromatous proliferation of bone (BPOP): an unusual foot mass in a child.This report describes an unusual case of bizarre parosteal osteochondromatous proliferation of bone (BPOP) which developed in the foot of an eight year-old child. Also described as Nora's lesion, BPOP is a rare benign bone tumor found most commonly in the hands and feet with a radiographic appearance occasionally confused with malignancy. Resembling osteochondromas at first glance, these lesions have a distinct radiographic and histologic appearance that permits differentiation from other benign lesions or low-grade malignant tumors. Treatment of BPOP consists of simple excision, although there is high rate of recurrence. Despite this high recurrence rate, there have been no reported metastases and local excision is still recommended.- - - - - - - - - - ranking = 1keywords = osteochondromas (Clic here for more details about this article) |
7/112. Hyperostotic macrodactyly and lipofibromatous hamartoma of the median nerve associated with carpal tunnel syndrome.A new case with 14-year follow-up of an extremely rare variety of congenital hand macrodactyly is presented. The disease characteristically presents a diffuse proliferation of fibrofatty tissue, but in this special type, osteocartilaginous deposits around the joints can also be found. The case presented included the troublesome feature of a lipofibromatous hamartoma in the median nerve at the wrist and its branches producing carpal tunnel syndrome. The patient obtained benefit from carpal tunnel release and epineurolysis. The hyperostotic development was managed with conservative resection of the periarticular osteochondromas. The literature reviewed suggests that the hyperostotic cases of macrodactyly do not differ from general cases of this congenital condition, except for the osteochondral deposits. These tumours develop during adulthood or after previous trauma, before epiphyseal closure.- - - - - - - - - - ranking = 1keywords = osteochondromas (Clic here for more details about this article) |
8/112. Acetabular dysplasia associated with hereditary multiple exostoses. A case report.Hereditary multiple exostoses is an autosomal dominant disorder characterised by multiple osteochondromata, most commonly affecting the forearm, knee and ankle. Osteochondromata of the proximal femur have been reported to occur in 30% to 90% of affected patients with coxa valga in 25%. Acetabular dysplasia is rare but has been described. This is the first report of a patient requiring surgical intervention. A girl was seen at the age of nine with hereditary multiple exostoses and when 12 developed bilateral pain in the groin. Radiographs showed severely dysplastic acetabula with less than 50% coverage of the femoral heads and widening of the medial joint space. Large sessile osteochondromata were present along the medial side of the femoral neck proximal to the lesser trochanter, with associated coxa valga. The case illustrates the importance of obtaining initial skeletal surveys in children with hereditary multiple exostoses to identify potential problems such as acetabular dysplasia and subluxation of the hip.- - - - - - - - - - ranking = 4.9870951824558keywords = hereditary multiple (Clic here for more details about this article) |
9/112. Multiple peripheral nerve compressions related to malignantly transformed hereditary multiple exostoses.Autosomal dominantly transmitted hereditary multiple exostoses is an uncommon disorder consisting of multiple projections of bone capped by cartilage. The lesions are most numerous in the metaphyses of long bones but may appear on flat bones. Sarcomatous transformation occurs in 1-25% of patients. We report a 33-year-old man with sciatica, previously diagnosed as hereditary multiple exostoses, presenting with multiple peripheral nerve compressions. Electrodiagnostic studies showed profound axon-loss multiple neuropathies involving the sciatic, superior gluteal, and inferior gluteal nerves. magnetic resonance imaging of the left pelvis showed a large mass in the sacral area that was suggestive of a chondrosarcoma. An open intralesional excision biopsy confirmed chondrosarcoma transformed from chondromatosis. Excision of the lesion was effective in eliminating the impingement of nerves and retarding progressive osseous growth. We suggest that malignant transformation be suspected in cases with focal compression neuropathy of patients known to have multiple exostoses. osteochondroma as a possible cause for compression neuropathy is discussed.- - - - - - - - - - ranking = 4.9870951824558keywords = hereditary multiple (Clic here for more details about this article) |
10/112. Scapular osteochondroma with reactive bursitis presenting as a chest wall tumour.A 32-year-old male presented with a painful, rapidly enlarging chest wall mass. A malignant chest wall neoplasm was suspected. A CT scan was performed which showed a mass extending from under the scapular and an exostosis arising from the anterior surface of the scapular. The mass and exostosis were resected resulting in complete resolution of symptoms. Histological examination showed the mass to be a reactive bursa, with no evidence of neoplasia.- - - - - - - - - - ranking = 2.8050925506234keywords = exostosis (Clic here for more details about this article) |
