A case of dermatomyositis is reported in a 50-year-old woman receiving D-Penicillamine therapy for rheumatoid arthritis. There was no evidence of neoplasia on full investigation. Remission of dermatomyositis occurred on withdrawal of D-Penicillamine.

A Caucasian male developed florid dermatomyositis documented by serum enzyme elevation, electromyography, and histology of skin and muscle. Serum enzymes, including creatine phosphokinase (CPK), aldolase, glutamic oxaloacetic transaminase (SGOT), and lactic dehydrogenase (LDH), decreased initially during high dose systemic corticosteroid therapy, although profound muscle weakness persisted. Subsequent elevation of serum LDH and SGOT levels during treatment provided a clue to underlying neoplasia. Primary hepatoma with widespread metastases was found at necropsy.

Multicentric reticulohistiocytosis developed in a 45-year-old woman, who had a 3 year history of untreated breast carcinoma. A review of the literature revealed that malignant disease has been associated with 27% of reported cases. It is considered that, like adult dermatomyositis, the onset of multicentric reticulohistiocytosis should stimulate detailed investigation for an underlying neoplasm.

Analysis of 102 patients with dermatomyositis, polymyositis, bullous pemphigoid, and dermatitis herpetiformis was undertaken to determine: (a) the incidence of occult malignant tumors in these diseases, and (b) the value of radiological screening to detect unsuspected malignant neoplasms. The incidence of internal malignant disease was no higher than that encountered in a control population. Radiological screening procedures routinely performed for patients with these disorders failed to disclose any occult neoplasms. A radiological tumor search has no place in the evaluation of these patients unless specific clinical findings suggest carcinoma in a particular organ system.

The present revision has been carried out in order to final out to what extent corticosteroids have improved the vital and functional prognosis of dermatomyositis. Over the sixties and in the early seventies, statistical tables have not shown any substantial differences compared with those of the pre-steroid era. It has been observed since 1973 that early treatment with high doses (1-2 mg of prednisone per kg per day) clearly improves the vital prognosis of infantile dermatomyositis, but not the functional one. In adults, there is less experience and the problem always exists of a possible underlying neoplasm. In cases with resistance to corticosteroids, the association of immunosuppressors, particulary methotrexate, has begun to be tested. There is no proved effective treatment of calcinosis which results in functional recovery.

An unusual type of prostatic carcinoma associated with crossed renal ectopia and dermatomyositis is reported in a young man. Infiltration by an epithelial tumor filled the enlarged prostate with soft papillary masses. Cystoprostatectomy and removal of a single large pelvic lymph node metastasis were done. Histologically, the tumor resembled endometrial carcinoma and may have arisen from paramesonephric tissue in the prostate. Large amounts of immunoglobulins were found in the tumor tissue. The patient has survived for more than 5 years, although a slow growing urethral recurrence has been noted.

Familial frequency of malignant neoplasms from 20 children with dermatomyositis was investigated and compared with 225 controls. Eight patients with dermatomyositis (40 per cent) had nine family members with a malignant tumour; this frequency is significantly higher than those found in the controls with juvenile rheumatoid arthritis (P less than 0.01), neoplasms (P less than 0.01), and a variety of diseases (P less than 0.05). This finding and the known association of neoplasm-dermatomyositis might suggest an hereditary predisposing factor, possibly a subtle inmune deficiency, common for tumours and dermatomyositis.

A partial review of selected published case reports of AD-P associated with malignancy has been enhanced by the presentation of pertinent data on 15 unreported examples of the association. It is noteworthy that the first case in current literature of AD-P associated with a malignancy was described in 1916. The brief clinical report of a patient with proximal muscle weakness and skin lesions, with the obvious association with a malignancy (adenocarcinoma of the stomach), describes an example that has been repeated many times with different types of tumors but with essentially no variations in the clinical findings. In 1959 Williams identified 590 cases of AD with an overall tumor rate of 15%, and recently Barnes identified 258 cases of AD associated with a malignancy. The original designation, dermatomyositis or AD, has now been expanded to include proximal muscle polymyositis with systemic involvement, which syndrome at the current state of the art is indistinguishable clinically and pathologically from AD except for the lack of skin lesions. It may be that at some future time one or more immunologic features may differnetiate the clinical entity polymyositis from AD and further subdivide each of these entitites from similar clinical syndromes associated with a malignancy. However, the problem in management in either AD or polymyositis is similar. A number of patients with a malignancy and muscle weakness or neuropathy have been reported. These associations have been mentioned briefly, but insufficient data are available to determine whether these should be considered as a variant of AD-P or only casually related conditions with certain clinical features in common. Most of the patients described in the literature of AD-P with an associated malignancy have had skin lesions; a minority only have lacked this feature. However, unless a patient is followed carefully, it is possible for a transient or evanescent erythema or insignificant skin lesions to be present and not recorded in the case record.

A 60 year old white man in previous good health presented with a 6 month history of progressive muscle weakness. Clinical and laboratory findings were typical of dermatomyositis. Muscle biopsy confirmed the presence of inflammatory myopathy; deposits of immunoglobulin G (IgG), immunoglobulin M (IgM) or third component of complement (C3) were not detected by immunofluorescence. No evidence was found for an associated neoplasm. An unexpected finding was the total absence of serum hemolytic complement activity. Further investigation revealed that the complement defect was attributable to a selective and total absence of the second component of complement (C2), as determined by both functional and immunoprecipitin assays. Family studies indicated that the defect was inherited in an autosomal recessive manner, as has been observed in the previously reported C2-deficient kindreds. This case demonstrates that typical muscle lesions of dermatomyositis can occur in the presence of a complement defect which would preclude activation of the classic (C1-C4-C2) complement pathway. The case is of further interest as one of a series of recently reported associations of rheumatic diseases with hereditary complement deficiencies. Study of the functional properties of the propositus' C2-deficient serum demonstrated normal generation of chemotactic activity in the presence of endotoxin or aggregated IgG, and normal or near normal bactericidal activity against Salmonella typhi O 901 and Hemophilus influenzae, type b. These findings emphasize the importance of the alternate (properdin) pathway of complement activiation in these functions.

Although there appears to be an increased incidence of malignancy among patients with dermatomyositis, demonstration of definitive statistical significance is precluded by the lack of large, controlled series. Patients with the two diseases tend to be older than the general dermatomyositis population and younger than those with cancer alone; and there is a preponderance of female patients. Tumors of the ovary and stomach are more frequently observed than in the general population, while colorectal malignancies are underrepresented. Most reported cases show development of the diseases within a year of one another, and, in some patients, the course of the myopathy follows that of the tumor. No definitive cause for the myopathy in these patients has been established.
