Biopsy techniques for skin, soft-tissue, and bone neoplasms.

This article discusses important aspects of the biopsy of neoplasms in skin, soft tissues, and bone. There are a variety of clinical conditions in which specific biopsy techniques are indicated. Inappropriate biopsy of tumors in these sites may compromise subsequent definitive therapy.

[Teleradiography and tomography in the search for pulmonary metastases in 132 cases of soft tissue and bone neoplasms].

In recent years whole lung tomography (WLT) has been considered mandatory in the staging of some neoplastic diseases, particularly of soft tissues and bone tumors. Since WLT is an exacting roentgen examination, its usefulness was evaluated by analysing 132 consecutive patients submitted to orthogonal chest roentgenograms and WLT, from January 1979 to October 1981 at the National Cancer Institute of Milan. A comparison between WLT and traditional chest X-ray examination was performed in order to evaluate how much tomography is significantly useful in improving diagnosis of lung metastases. From this analysis, the authors conclude that WLT is generally unnecessary when chest roentgenograms are negative, whereas it is useful when single or multiple lung metastases are already evident by traditional X-ray examination. In these cases WLT allows a more accurate identification of the metastases from the point of view of their number and site, which is important not only for the treatment choice but also for the check of its effectiveness.

The World Health Organization's histologic classification of bone tumors. A commentary on the second edition.

BACKGROUND: The World Health Organization's histologic classification of bone tumors was revised in 1993. METHODS: The first edition was reviewed by an international panel of pathologists from nine countries and modified to incorporate advances made in the twenty years since it appeared. RESULTS: The framework and concept of the classification remain the same (i.e., based on histologic criteria in terms of differentiation shown by the tumor cells via conventional light microscopy supplemented by immunohistochemistry). New entities not described in the first edition include, for example, benign and malignant fibrous histiocytomas, well differentiated osteosarcoma, round-cell osteosarcoma, clear cell chondrosarcoma, primitive neuroectodermal tumor of bone, osteofibrous dysplasia, and giant cell reparative granuloma. CONCLUSION: The revised and expanded classification reflects advances in our knowledge, but is similar in concept and framework to the original version to allow comparisons between data collected in the past and future.

Fibro-osseous, osseous, and cartilaginous lesions of the orbit and paraorbital region. Correlative clinicopathologic and radiographic features, including the diagnostic role of CT and MR imaging.

Fibro-osseous and cartilaginous lesions of the orbit and facial region share overlapping clinical, radiologic, and pathologic features that may lead to diagnostic confusion and possible misdiagnosis. The value of imaging studies in the histopathologic diagnosis of these lesions cannot be overemphasized. The histopathologic diagnosis of such lesions should not be rendered in the absence of radiographic correlation.

Benign cartilaginous lesions of the upper extremity.

Common and rare benign cartilaginous neoplasms and diseases of multiple cartilaginous lesions are discussed. Particular attention is paid to patient demographics, physical and radiographic findings, pathology, and treatment.
