“…Simultaneous performance of NMB and open biopsy in each patient would more accurately assess the relative sensitivity of the 2 methods, and is a prospective project that warrants further exploration. However, our results compare favorably with previously published data on similar patient populations, which reveal a specific pathologic diagnosis in 46-75% of open biopsies (1, 11,14,15) and in 37-50% of NMBs (1,4,16).…”

Objective. To determine the usefulness of a unique method of percutaneous needle muscle biopsy (NMB) in patients with suspected idiopathic inflammatory myopathy (IIM).Methods. The yield of percutaneous NMB was studied in 55 patients who were found to have a combination of clinical, laboratory, or electromyographic features of IIM.Results. A diagnosis of IIM was confirmed histopathologically in 29 patients (53%), other specific myopathies were found in 5 (9%), nonspecific myopathic changes were present in 11 (20%), and a neurogenic process was diagnosed in 3 (5%). Nonspecific changes or no abnormalities were present in 7 patients (13%). Followup of the 18 patients with nonspecific histopathologic findings disclosed that only 3 had a subsequent disease course compatible with IIM.Conclusion. Percutaneous NMB is a safe, convenient, and relatively inexpensive method of muscle biopsy, with a high diagnostic yield for the pathologic confirmation of IIM. It should be considered as a primary method of acquiring muscle for histopathologic examination in the evaluation of suspected IIM.Histopathologic examination of muscle is invaluable in the evaluation of most patients with suspected myopathy. Although generally safe and well-tolerated, open muscle biopsy is costly and requires the assistance of a surgeon, an operative theater, and local or regional anesthetics (1). In contrast, various techniques of "percutaneous" needle muscle biopsy (NMB) (1) offer a more convenient and cost-effective means of obtaining

“…This is slightly less than most pre vious estimates [2,3,8,9] and substantially less than some [10], but studies indicating these higher figures have been criticized for potential inclusion of patients w'ith tumor and other neuromyopathic processes [11]. The review' of Bohan et al [7] found that der matomyositis and polymyositis were equally common in malignancy, and that the only clinical distinction from individuals without tumor was age, cancer patients being older.…”

Dermatomyositis Associated with Chronic Myelogenous Leukemia

Dermatomyositis and polymyositis have been well established in association with malignant neoplastic disease. Most commonly, this association has been noted in patients with solid tumors rather than in patients with neoplasms of hematopoietic origin. We describe here a patient with chronic myelogenous leukemia who developed typical dermatomyositis, which responded to therapy with corticosteroids. This concurrence has been reported in only one previous patient to our knowledge. The nature and implications of the association of dermatomyositis and neoplasia are discussed.

The association of polymyositis (PM) and rheumatoid arthritis (RA) is described in a 40-year-old female Mexican patient who was studied for a long period of time. The characteristic changes of PM that preceded the onset of RA for 7 years included proximal symmetrical muscle weakness, increased creatine kinase activity, and distinctive electromyography and muscle biopsy results. The occurrence of RA during the final 4 years of the 11-year period was characterized by long-lasting deforming and symmetric polyarthritis, high positive rheumatoid factor, subcutaneous nodules, and erosive joint changes. Through observation, myopathic changes other than those from PM were excluded. Joint changes other than from RA were also ruled out. A review of the literature revealed few specific reports of the coexistence of both diseases.
