An effort was made to identify all patients with polymyositis/dermatomyositis (PM/DM) admitted to hospitals in Israel from 1956-1976. The diagnosis of PM/DM was retrospectively reviewed in 92 (46 definite, 26 probable, and 20 possible) cases. The most common complaints and physical findings in the course of the disease were muscle weakness (86 patients), rash (53 patients), arthritis or arthralgia (39 patients), and dysphagia (35 patients). Elevated serum aldolase levels were found in 64% of the patients for whom data were available; 92% had abnormal electromyogram results, and 60.9% had muscle histopathology consistent with PM/DM. Malignancy was diagnosed in 13 patients. Malignancy, ischemic heart disease, and pulmonary complications were the most common causes of death. The actuarial survival curve was heterogeneous, with an accelerated mortality during the first year after diagnosis and a slower mortality during the following 7 years. Independent unfavorable prognostic signs were: failure to induce remission, leukocytosis, fever, older age, a shorter disease history, and dysphagia.

Of 12 patients with adult dermatomyositis studied, 5 (41%) had associated malignancies, of which 3 were nasopharyngeal carcinomas. The youngest was a 23-year-old woman. In view of the high incidence of cancer and the predominance of nasopharyngeal carcinoma, malignancy evaluation in Chinese patients from the Far East, 20 years of age or older with dermatomyositis should have extended workups for postnasal cancer. Two patients who had positive antinuclear not have associated cancers. Three patients died of acute myocardial infarction.

The association between dermatomyositis and malignant tumors, especially carcinomas, is well documented. However, lymphoreticular malignancies have rarely been reported. A patient in whom Hodgkin's disease was diagnosed 5.5 years after the onset of dermatomyositis is described. The independent course of the two diseases is discussed and previously reported cases of lymphoma and dermatomyositis are reviewed.

Of 105 cases seen over 12 years with mean 4 years followup, there were 69 with polymyositis (PM) and 36 with dermatomyositis (DM). and in 43 this complicated another connective tissue disease (CTD). Primary PM had onset a decade later than others and most severe myopathy occurred in DM. Earliest symptoms were polyarthritis and Raynaud's phenomenon with frequent sicca syndrome (51%). The less than universal prevalence of elevated muscle enzymes (68%), myopathic electromyography (86%). and abnormal muscle biopsy (78%) emphasizes the need for complete evaluation in all cases. Improvement occurred in 69% overall, including all 23 given no therapy or low dose corticosteroids and 59% of the remainder who received high dose corticosteroids with added cytotoxics in one-quarter. Outcome was worse in older patients and in those where weakness exceeded 4 months before diagnosis. Eight of 19 deaths were due to myositis or its therapy which also caused considerable morbidity. Malignancy in 16 cases was temporally related to myositis in half of these cases.

The authors report the case of a 56 year-old woman presenting with dermatomyositis revealing a cancer of the colon at the ganglial dissemination stage. Exeresis led to the regression of the dermatomyositis and allowed an attenuation of the steroid therapy. The muscular and cutaneous signs reappeared within six months, evidencing a metastatic hepatic dissemination. Death came within six months of the appearance of the dermatomyositis. The authors review the literature concerning dermatomyositis associated with cancers of the digestive tract in general, and of the colon in particular. This association is found in about 6 to 35% of cases of dermatomyositis, which is the most common paraneoplastic skin associated with cancers of the colon.

Polydermatomyositis is a chronic, non-suppurative disease of the striated muscle. In practice, the diagnostic criteria are often associated with other factors--alcoholism, corticotherapy--which, by themselves, may induce myopathy. In adults, the possible association of dermatomyositis with cancer rises the problem of scanning for neoplasia at regular intervals. In addition to corticotherapy, physical therapy helps the patient to maintain maximal autonomy.

Forty-four patients with polymyositis/dermatomyositis (PM/DM) were studied for precipitating antibody to Jo-1. Ten (23%) had anti-Jo-1 antibodies including 8 (47%) of 17 PM patients and 2 (15%) of 13 PM-overlap patients. None of the 11 DM nor 3 PM/DM-cancer patients had anti-Jo-1 antibody. Interstitial pulmonary disease was present in 5 (50%) of the 10 anti-Jo-1 positive compared to 5 (13%) of the 34 anti-Jo-1 negative patients (odds ratio = 5.8, p = 0.05). No differences in other demographic or clinical features or survivorship were noted between these groups. These data confirm the association of anti-Jo-1 antibody with an increased frequency of interstitial pulmonary disease in PM/DM patients.

A unique case of an osteosarcoma arising within a hamartoma of the thymic gland located in the left pleural cavity of an 11-year-old girl is described. The presence of abundant mature lamellar bone within this thymic hamartoma provides an explanation for the osseous histogenesis of the sarcoma. The development of an osteosarcoma from extraskeletal osseous tissue is a rare occurrence and has been documented in association with myositis ossificans and most recently in a case of dermatomyositis with metaplastic ossification.

Risk factors for epithelial ovarian cancer are summarized in Table 1. Calculation of ovulation-years appears to be a potentially useful and practical method for identification of the high-risk individual. Risk factors for nonepithelial ovarian cancer are largely unknown, and consequently clinical diagnosis is stressed in the early detection of these tumors. Patients with Peutz-Jeghers syndrome or ovarian dysgenesis are significantly at risk and require at least regular pelvic examination. Of course, individuals with sexual precocity are at high risk for sex cord/stromal or germ cell malignancies. Individuals with a family history of Sertoli-Leydig cell tumors and benign thyroid disease also deserve close observation. Early clinical detection requires a sensitivity to presenting symptomatology (e.g., diffuse abdominopelvic complaints) as well as the skill and knowledge needed to recognize and appropriately manage adnexal masses. Harbingers of ovarian malignancy in the elderly woman, including unexplained hypercalcemia, new onset dermatomyositis, and cerebellar degeneration, should motivate thorough gynecologic evaluation. While radionuclide ovarian imaging for detection of early epithelial cancers of the ovary may become more generally available in the future, ultrasound imaging of the postmenopausal ovary, and peritoneal cytology may be of immediate value in screening high-risk women.

Evidence has been presented supporting a causal relationship between malignancies and musculoskeletal syndromes. This discussion has dealt primarily with lesser known relationships, more common associations such as hypertrophic osteoarthropathy and dermatomyositis being reviewed elsewhere. The ones discussed herein closely mimic primary connective tissue diseases and offer an insight into the study of the pathogenesis of these primary diseases. In view of the natural history of malignant disease, the hope for such patients arises from the physicians early diagnosis and treatment of the underlying malignancy. Early diagnosis and treatment may in turn be entirely dependent on the physician's awareness of a musculoskeletal syndrome being the presenting feature of an otherwise occult neoplasm. Several connective tissue syndromes appear to predispose to the development of malignancy, and increasing evidence suggests that this development of malignancy may be further enhanced by immunosuppressive therapy.
