Sarcoidosis Presenting as Dorsal Wrist Mass: A Case Report.

Patients with sarcoidosis have an indolent course in which the disease is not detected unless seemingly benign symptoms appear. Such was the case in a 42-year-old man who was referred to the orthopedic service for evaluation of a slowly enlarging mass over the left wrist without prior history of trauma. In this article, we will review the symptoms and histopathology of sarcoidosis with a particular focus on orthopedic manifestations of the disease.

Malignant Lymphoma Mimicking an Infection After Shoulder Surgery.

Involvement of the musculoskeletal system by primary or metastatic malignant neoplasms mimicking common orthopaedic conditions is well recognized. The diagnosis may be delayed in the absence of radiographic abnormalities. Twenty-five percent of lymphoma cases have skeletal involvement, and they can affect both bone and soft tissue.

Prophylactic oral antibiotics reduce reinfection rates following two-stage revision total knee arthroplasty.

The purpose of this study was to compare the incidence of reinfection in patients who received oral antibiotic prophylaxis with those who did not following two-stage revision knee arthroplasty. Additional purposes included: (1) comparison of these findings to the infection rate in patients who underwent revision for aseptic reasons, and (2) characterisation of the organisms responsible for reinfection following revision procedures. Twenty-eight two-stage revision knee arthroplasty procedures were followed up by a mean of 33 days of oral antibiotics (range, 28-43 days), while the remaining 38 procedures received only 24-72 hours of in-patient antibiotics.
