Many malignant tumors have a morphologically recognizable precursor lesion. As screening and early detection have better our skill to notice lesions at more and more prior phases of progress, an elevated variety of precancerous lesions are visible by means of pathologists. regrettably, an absence of uniform histologic standards for precursors present in many organs could make diagnostic interpretation tough.

Not only is the spectrum of severity of many disorders variable but there is considerable overlap between them. g. g. CMT, CPEO). Careful correlation with all ancillary data is then needed and knowledge of the information that can be obtained from the tests requested, as well as their limitations, required. Muscle biopsy is often helpful in directing diagnosis but in some disorders it is noncontributory. Imaging techniques have an increasing role in the diagnosis of neuromuscular disorders. Advances in molecular techniques, such as nextgeneration sequencing, will broaden the spectrum of understanding of several disorders and the challenge will be to identify pathogenic changes.
The alternative is that the mutation shows incomplete penetrance, with some individuals carrying the mutation but not manifesting the disease. Identifying the precise disease-causing mutation in the patient also allows determination of whether the mutation is de novo, that is, not present in the blood lymphocyte DNA from either parent. Furthermore, in the situation of an apparent de novo mutation, there is also the possibility that one of the parents is a mosaic, including a germline mosaic, for the mutation present in their child.
E. acid maltase deficiency and inflammatory myopathies, fibrillation potentials and positive sharp waves may be recorded. 16 Myotonic conditions produce a characteristic EMG pattern, with spontaneous bursts of potentials in rapid succession, waxing and waning, and a characteristic acoustic signal. Repetitive nerve stimulation and especially single-fiber EMG are of value in assessing neuromuscular junction disorders. Imaging of skeletal muscle, peripheral, and central nervous tissue Ultrasonography (US) and computed tomography (CT) have been used for many years to identify the extent and distribution of muscle changes in neuromuscular disorders but MRI has become the gold standard for imaging muscle involvement in inherited and acquired muscle disorders.
