Distal clavicle osteolysis after acromioclavicular joint stabilization has only been described after the use of hardware for clavicle stabilization or synthetic graft causing a foreign body reaction. This paper reports a very rare case of distal clavicle osteolysis after modified Weaver-Dunn procedure for the treatment of chronic acromioclavicular joint dislocation. The paper also provides a co...

Liposarcoma is one of the most common malignant soft tissue tumours. It usually presents as a single mass, and the prognosis varies according to the degree of histological differentiation. Multicentric liposarcoma is an unusual presentation of this tumour in which several independent lesions develop and generally display an aggressive pattern. It may be difficult to establish a precise diagnosi...

INTRODUCTION: Osteolysis adjacent to the acetabular component of hip prostheses remains the most challenging complication of total hip arthroplasty in the medium to long-term. This loss of bone can cause the prosthesis to lose fixation and, when severe enough, can lead to fracture of the pelvis. Therefore, knowledge of how osteolysis develops and progresses is important in order to develop opti...

Giant cell tumors (GCTs) of bone commonly affect a single bone. Most of vertebral lesions occur in the sacrum rather than in the spine above the sacrum. Multicentric GCTs are rare. They may occur synchronously or metachronously and therefore may be identified at the same time in different anatomic locations or at different times in different anatomic locations. Synchronous tumors reportedly occ...

The case is reported of a 63 year old man presenting with a rapidly destructive symmetrical polyarthritis and widespread papular nodular skin lesions, confirmed by a biopsy to be due to multicentric reticulohistiocytosis. Biventricular cardiac failure developed secondary to extensive myocardial infiltration with multicentric reticulohistiocytosis, a complication of this disease which has not pr...

Wear particle-induced inflammatory osteolysis is the primary cause of aseptic loosening, which is the most common reason for total hip arthroplasty (THA) failure in the med- and long term. Recent studies have suggested an important role of gut microbiota (GM) in modulating the host metabolism and immune system, leading to alterations in bone mass. Probiotic bacteria administered in adequate amo...

Adult T-cell leukemia-lymphoma (ATLL) is caused by human T-cell lymphotrophic virus I (HTLV-I) infection. Among ATLL cases, 70% of patients present with leukemia and the remaining patients present with lymphoma. Hand osteolysis in the patients with ATLL is considered as paraneoplastic syndrome and caused by parathyroid hormone-related peptide (PTHrP) released from tumor cells. Radiographic feat...

Idiopathic osteolysis (Gorham's disease) is an extremely rare occurrence. The etiology of osteolysis is as yet unknown. A history of minor trauma may be a factor. Bones begin to resorb, partially or completely as a localized erosion, and from this, slow centrifugal absorption of a large piece of the skeleton takes place. The osteolytic process may halt spontaneously after years of progression. ...
