Musculoskeletal Key

There are many inherited and acquired clinical disorders caused by a defect in upper or lower motor neurone or the peripheral nerve. These include amyotrophic lateral sclerosis (ALS; upper and…

Skeletal muscle undergoes many changes in response to disease and trauma. With the electron microscope, the abnormalities seen at the light level can be characterized and accurately localized, and the…

Immunohistochemistry Immunohistochemistry has an essential role in the evaluation of muscle biopsies and in examining protein localization. The term ‘protein expression’ is often applied to describe immunohistochemical results, but it…

When the pathologist is asked to evaluate a muscle biopsy, much of the interpretation is based on his or her previous experience and the recognition of similarities between the biopsy…

The first section of this book covered techniques and general aspects of interpretation of pathological changes. We now turn our attention to specific disorders and the variable role muscle biopsy…

This chapter deals with the various changes that may occur in a muscle under pathological conditions. As we show, very few abnormalities are in themselves pathognomonic of a particular disease….

In this chapter, the composition and appearance of normal muscle will be discussed. The first part will be concerned with the anatomical constituents of normal muscle at the light microscope…

The Evolving Role of Muscle Pathology Muscle biopsy has been an important part of the assessment of patients with a neuromuscular disorder for many decades. The use of frozen sections…

Just as every pathologist has particular preferences for routine stains, so muscle histochemists have tended to develop preferences for particular reactions, especially in the interpretation of fibre types. In the…
