Although much remains to be learned about the immune-mediated myositis syndromes, information generated from recent studies in a number of areas may assist physicians in patient management. Topics reviewed here include: data supporting the association of myositis with cancer and the appropriate evaluations for malignancy in a myositis patient; an approach to the assessment of patients with dermatomyositis sine myositis; the usefulness of the clinicopathological and serological classifications; a discussion of whether childhood and adult myositis are the same or different entities; a review of those prognostic factors to consider in the clinical management of myositis patients; current approaches and their limitations for assessing disease activity and damage. To improve our limited understanding of the myositis syndromes, national and international collaborations are needed to obtain the necessary numbers of subjects, given the rarity and heterogeneity of these disorders.

Although sarcoidosis has occasionally been associated with hemoglobinopathies, its association with dermatomyositis is extremely rare. A 24 y/o African American male with hemoglobin SC disease developed proximal weakness. He had heliotrope rash, muscle weakness, elevated serum CK, myositis by EMG, and no malignancy. A muscle biopsy confirmed dermatomyositis. Two years later, he was hospitalized with constitutional and respiratory symptoms and parotid enlargement. Chest X-ray and CT scan showed diffuse micronodular infiltration in both lungs and mediastinal lymphadenopathy. A transbronchial lung biopsy revealed non-caseating granulomata consistent with sarcoidosis. AFB and fungal stains and cultures were negative. Thus, in this case, sarcoidosis developed after or in association with dermatomyositis. A review of world's literature showed five other non-identical cases of dermatomyositis associated with sarcoidosis.

We describe a 53-year-old white woman with dermatomyositis (DM) who had additional clinical findings of pityriasis rubra pilaris (type Wong dermatomyositis) with histopathologic features of both pityriasis rubra pilaris (PRP) and porokeratosis. Type Wong dermatomyositis was originally described in 11 patients by Wong in 1969 and has been reported in 5 additional patients. This is a rarely described phenomenon in which patients with DM develop cutaneous hyperkeratotic lesions that resemble PRP and histologically show follicular hyperkeratosis and hair follicle destruction. Arrector pilorum muscles also show degenerative findings and myositis. We believe that this is the first reported case of a patient with type Wong DM who also has clinical and histologic features suggestive of porokeratosis. This is important because of the association of adult-onset dermatomyositis with internal malignancy and the well-documented association of porokeratosis with immunosuppression. These clinical and histologic findings serve as markers for malignancy in patients with DM. These patients warrant a complete review of systems and investigation for age-appropriate neoplasms as well as close long-term follow-up by dermatologists to ensure that these cutaneous eruptions are not overlooked.

The exact nature of the relation between malignancy and myositis has created continued controversy. Most of the evidence points toward an association between dermatomyositis (DM) with malignancy. The relation with polymyositis is much weaker, if at all present. The first 5 years after DM diagnosis is when the risk is greatest for malignancy. Although types of malignancy seen in DM and polymyositis are similar to those in the general population, ovarian cancer seems to be more common in DM. Most experts recommend that otherwise asymptomatic patients with DM have an age-specific examination for occult malignancy. All suggestive symptoms or clinical clues should be evaluated thoroughly.

Myositis ossificans originating from the chest wall is extremely rare. We report a case of myositis ossificans occurring in a young woman with progressive painful swelling in the chest wall. Preoperative examination suggested a malignant neoplasm originating from soft tissue. Although rare, myositis ossificans is one of the potential causes of painful swelling in the chest wall, and can be mistaken for a malignant neoplasm.

Eosinophilia is occasionally a feature of rheumatic disease. The differential diagnosis of eosinophilia includes parasitic infection, systemic vasculitides, eosinophilic arthritis, and myopathies, together with the idiopathic hypereosinophilic syndrome and malignancy. Careful evaluation of the patient should enable an accurate diagnosis to be made. Parasitic infection is the commonest cause of eosinophilia worldwide and can cause systemic disease, as illustrated by the report of Sarcocystis myositis in a group of military personnel in Malaysia. A persistent arthropathy associated with eosinophilia, but not with parasitic infection, has been reported from the far East. Drugs may also cause eosinophilia, and there has recently been much discussion of the relation between Churg-Strauss syndrome and the leukotriene antagonist zafirlukast. The present view is that reduction of steroid dose allows unmasking of previously undiagnosed Churg-Strauss syndrome. The idiopathic hypereosinophilic syndrome may represent a lymphoproliferative process; evidence for this comes from the demonstration that many patients have a clonally expanded population of aberrant T cells.

We describe a rare case of proliferative myositis affecting the lateral border of the tongue. The site of the lesion and its gross pathological presentation were highly suggestive of a malignant process. Subsequent biopsy and characteristic histological appearance led to the diagnosis of this benign condition. This is the first reported case of a painful presentation of proliferative myositis involving the tongue. This report serves to remind the head and neck surgeon of the need to obtain histological diagnosis of malignancy before embarking upon radical surgical treatment. We recommend careful follow-up to ensure complete resolution of the lesion.

The polymyalgic syndrome may be the presenting clinical feature for several diseases such as polymyalgia rheumatica, temporal arteritis, malignancy, rheumatoid arthritis, virus infections, connective tissue diseases, and myositis. In this review we present the various diagnostic options seen from a rheumatological point of view, with emphasis on polymyalgia rheumatica, temporal arteritis and the paraneoplastic syndrome. We are of the opinion that polymyalgia rheumatica is overdiagnosed in general practice, and steroid treatment may delay diagnosis and treatment of other differential diagnosis presenting as the polymyalgic syndrome. Several recently published Norwegian epidemiological studies offer new information on various aspects of the polymyalgic syndrome, which will be discussed.

Dermatomyositis (DM) is an inflammatory myopathy characterized by a typical cutaneous rash and proximal weakness. DM results from endothelium deposition of the complement membranolytic attack complex C5b-9, followed by inflammation. It is thus possible to have cases of DM with the typical rash, but with no associated myositis--amiopathic DM. DM represents a higher risk of association with malignancy and sometimes behaves as a paraneoplastic syndrome. As DM can be the alarm sign, once diagnosed, exclusion of malignancy should be done. In this article we also discuss the treatment and prognosis of dermatomyositis, according to the literature.

Dermatomyositis is a disease that has a characteristic skin eruption that may occur with or without a proximal myopathy. The disease with cutaneous features only is classified as amyopathic dermatomyositis. The origin is unknown, but autoimmune factors are believed to play an important role. Autoantibodies are found in most patients and some have myositis-specific antibodies. Systemic changes may occur and there appears to be a relationship to internal malignancy, particularly in older patients. Juvenile disease has an associated vasculopathy. Treatment includes systemic corticosteroids and other immunosuppressive agents. The cutaneous changes may be difficult to treat.
