Leiomyosarcoma in bone: primary or secondary? A case report and review of the literature.

Our case demonstrates how metastases may be present and symptomatic long before they produce sufficient osseous changes to render the lesions radiologically detectable. A case of leiomyosarcoma arising in the uterus and initially presenting as a femoral lesion is presented. It required an intensive review of the case history and of the previous pathology in order to identify the primary site in the uterus. In the literature nine cases of metastatic leiomyosarcoma presenting initially in bone are reviewed. Ten additional cases from the literature showed bone metastases as the first site of recurrence. When this is assessed together with some 14 cases of primary leiomyosarcomas reported arising in bone, one is impressed that this is an uncommon tumour in bone either as a primary or secondary. In all patients in whom a leiomyosarcoma is histologically proven in bone, all primary sites should be specifically and categorically excluded before the lesion is accepted as an osseous primary. This should include special stains for myofibrils and electron microscopy if at all possible, in order to differentiate such tumours from other sarcomas such as fibrosarcoma. This applies especially to patients with uterine lesions that have been previously treated, even if they have been regarded as benign initially. All previous pathology and in particular hysterectomy specimens should be carefully reviewed. The need to specifically identify a leiomyosarcoma as a primary lies in the different modalities of treatment used: aggressive ablative surgery for primary lesions as opposed to radiation and chemotherapy for metastatic disease.

Bone Neoplasms

Primary osteomyelitis caused by coagulase-negative staphylococci.

Coagulase-negative staphylococci (CONS) are occasionally cultured from foci of osteomyelitis in otherwise healthy individuals and are usually regarded as contaminants. The present report describes two children with subacute osteomyelitis of the distal tibia in which pure cultures of CONS were obtained from bone. In one patient, the infection was multifocal, and CONS were isolated from two anatomical sites at two different times. In the other patient, the infection was unifocal, and CONS were cultured from two separate specimens obtained from the same site. In both patients, the symptoms progressed until appropriate antibiotic treatment was initiated. CONS isolated from cultures of bone should not automatically be disregarded. Appropriate antibiotic therapy may result in clinical resolution.

Current techniques of limb lengthening.

Limb lengthening is still a major procedure with potentially serious complications. It does not, however, deserve the reputation it gained over the last few years. With a proper understanding of the biology, biomechanics, and strategies of lengthening, excellent results can be consistently obtained with relatively few complications.

Achondroplasia

Chronic repetitive unrecognized flexion injury of the cervical spine (high jumper's neck).

Unrecognized flexion injuries of the cervical spine may lead to late instability and neurologic damage. These hidden flexion injuries may be from acute or chronic traumatic episodes. Cervical spine instability was seen in an amateur high jumper as a result of chronic repetitive flexion loading of her cervical spine due to incorrect landing technique. The instability from these types of flexion injuries is generally unrecognized on a routine lateral radiograph. The presence of slight anterior subluxation, simple compression fractures, or subtle kyphotic angulation at one cervical level should alert the physician to this diagnosis. Flexion extension views are useful to demonstrate this instability. Occupations and sports which involve repetitive flexion stress to the cervical spine are at risk for this type of late instability. Therefore, in high jumping careful attention to safe techniques of landing is of utmost importance.
