The authors describe two patients suffering from cancer accompanied with paraneoplastic skin disorders (bullous pemphigoid, dermatomyositis). Before the diagnosis of stomach cancer was obtained by X-ray examination, the IgM-level was found lower than in normal persons. The value of the IgM-estimation in the serum seems to be high in the diagnosis of tumours. Other causes of the decreased IgM-level than tumours and paraneoplastic disorders of the skin were not found.

The remote effects of cancer on the neuromuscular system include type II muscle fiber atrophy, dermatomyositis/polymyositis, myasthenia gravis, the facilitating myasthenic syndrome, peripheral neuropathy (including amyloid neuropathy), and possibly amyotrophic lateral sclerosis. The clinical and pathological findings and a number of possible pathokinetic mechanisms of these disorders are discussed. In none is the pathokinetic mechanism known. Hence, much work remains in therapeutically oriented research of the mechanisms in all of the remote effects of cancer on the neuromuscular system.

In contrast to the 15-20% incidence of the coexistence of acute dermatomyositis-polymyositis and malignancy, it has been accepted traditionally that the association of progressive systemic sclerosis, a disease with several features that may overlap the former condition, and malignancy is purely fortuitous. This experience has not been altered by the material presented in this review. However, the factual coexistence has been illuminated by a review of the pertinent literature and presentation of 12 previously unpublished case reports. Four cases concern pulmonary malignancies in PSS; eight are of an associated non-pulmonary malignancy. In the first group, the development of a malignancy superimposed on the chronic fibrosing changes in the lungs of PSS does not seem so strange, particularly in view of a possible immunologic reaction by collagen in considering pathogenesis. This immunologic process might be similar to a related immunologic process responsible for the development of malignant cells in pulmonary and other tissue, where normal cells usually are found. The high incidence of males is related to the high incidence of males in Veterans Administration Hospitals, the principal population source of these cases.

In this case of dermatomyositis, the patient's clinical course was complicated by the development of acute granulocytic leukemia. Various malignancies complicating dermatomyositis have been reported in the literature. Rarely have these been of the hematopoietic system.

Methotrexate is now used widely for the treatment of acute leukemia, non-Hodgkin's lymphoma, osteogenic sarcoma, choriocarcinoma, breast carcinoma, pulmonary and epidermoid carcinoma, and intrathecal chemotherapy. It is also useful in bone marrow transplantation, severe psoriasis, rheumatoid arthritis, dermatomyositis, Wegener's granulomatosis and sarcoidosis. The recent dramatic intensification of methotrexate therapy can be attributed in part to advances in our understanding of the clinical pharmacology of the folate antagonists, as well as to the combination of positive results and their effective dissemination to medical oncologists. The review summarizes the pharmacologic findings and illustrates how they are currently being applied to the treatment of malignant disease.

Thirty-two patients with adult-onset polymyositis uncomplicated by cancer or systemic connective tissue disease were studied. Muscle biopsy specimens were examined with direct immunofluorescence microscopy and results were compared with those in 94 control subjects. Sarcolemmal and sarcoplasmic staining were observed in both groups and considered to be nonspecific. Immune deposits in the muscle microvasculature were present in some cases of systemic lupus erythematosus and dermatomyositis but were not present in polymyositis. Our data suggest that the finding of vascular immunofluorescence excludes the diagnosis of adult polymyositis and implies that the pathogenesis of this disease and other idiopathic inflammatory myopathies may differ.

Two cases of cancer, each associated with a different collagen-vascular disease, are reported. The first patient, a 71-year-old white man, had a history of acute dermatomyositis and malignancy for a few weeks only. Death was associated with adenocarcinoma of the lesser curvature of the stomach with metastases to the liver and beyond. The second patient, a 69-year-old white man, had had symptoms associated with Raynaud's phenomenon for more than a decade and difficulty in swallowing, attributed to progressive systemic sclerosis for more than two years. He died with an epidermoid carcinoma of the esophagus with extension to the lung and metastases to the liver and lungs.

Dermatomyositis and polymyositis are diseases which must be carefully defined in each patient. Criteria such as those suggested by Bohan and Peter will help define the disease and exclude other possible causes of myositis. Immunological factors are probably involved in the pathogenesis of the disease, although varied types of injury may manifest in clinically similar disease. Dermatomyositis, not polymyositis, is related to internal malignancy in adults; however, an extensive malignancy evaluation is not indicated. Therapy with corticosteroids will improve the quality of life, will prevent contractures and calcinosis and may improve the chance of survival. In cases where steroids are ineffective, immunosuppressives may be helpful.

All cases of dermatomyositis-polymyositis in women seen between 1970 and 1977 at Baylor Affiliated Hospitals were reviewed. Twenty-five patients were identified with this diagnosis. Of these women, 5 were found to have a malignant tumor: 3 ovarian carcinomas, 1 cervical intraepithelial carcinoma, and 1 colon carcinoma. Pertinent histologic and clinical findings in patients with dermatomyositis-polymyositis are discussed. The high prevalence of malignancy in these patients, previously recognized, is discussed. A case report is presented.

Nonspecific dermatologic problems occasionally associated with malignant disease include pruritus, reactive erythemas and skin infections. Frequently associated with internal neoplasms are acanthosis nigricans, dermatomyositis, rapid development of multiple seborrheic keratoses, hypertrichosis lanuginosa and other syndromes. Skin metastases may be the first signs of internal cancer. The most common visceral primaries are the lung and colon in men and the breast, colon and ovary in women. Recognizing these lesions can lead to early diagnosis and improved prognosis.
