Dermatomyositis is a rare disease of unknown origin, which affects both children and adults. In the juvenile form, dermatomyositis is a multisystem disease, characterized by myositis; an erythematous rash over the bridge of the nose, around the eyes, and on the trunk and limbs; vasculitis; and dilatation of the capillaries in the nail beds and gum margin. Late development of calcinosis is seen in approximately two-thirds of the patients. This case describes a 5-year-old dental patient diagnosed with dermatomyositis. This article includes the clinical manifestations of dermatomyositis in the body and in the oral cavity as well as the considerations that should be taken when treating these patients.

A 62-year-old man was admitted to hospital with general malaise, arthralgia, edema, and high-grade fever. He was diagnosed as dermatomyositis because of typical skin rashes and muscle weakness. His symptoms were improved by high-doses of prednisolone and cyclosporin A, with the exception of the skin rash over the back. High-grade fever developed again when tapering prednisolone. His condition deteriorated gradually. Paresthesia, hypothyroidism, metabolic acidosis, and disseminated intravascular coagulopathy occurred, and he died eight months after the first admission. Postmortem examination revealed intravascular proliferation of atypical mononuclear cells in the lumens of small vessels in all organs. Intravascular lymphomatosis (B cell type) was diagnosed.

Dermatomyositis is a rare inflammatory disease with a difficult diagnosis on cutaneous biopsies, since alterations are often little marked and non specific. A 52-year-old patient had severe paraneoplastic dermatomyositis. He had an erythematous rash on the trunk, and erythematous papules on the back of the hands. The first histological cutaneous lesion was a striking arrector pili myositis. Arrector pili myositis has rarely been described, and is thought to be linked with Wong type eruption occurring in dermatomyositis. Arrector pili myositis might constitute an helpful sign in the diagnosis of dermatomyositis, but its specificity and sensitivity are unknown. We compared this case to four previously reported cases. In these five cases, arrector pili myositis was not associated with a particular sub-type of dermatomyositis or with poor prognosis.

Dermatomyositis and polymyositis are the two major idiopathic inflammatory myopathies. The Bohan and Peter's criteria are still useful despite the probably different pathogenesis of the two myopathies. Cutaneous manifestations of dermatomyositis include heliotrope rash and Gottron's papules. The heliotrope rash, with or without edema, in a distribution involving periorbital skin is very suggestive of the diagnosis. Papules may be found overlying the "kneedle" of the hand or the elbows, knees, feet. Periungueal erythema with telangiectasis were characteristic but not pathognomonic. Scalp involvement is common. Skin lesions of dermatomyositis may precede the development of the myopathy and may persist after the control of the myositis. Some patients have an amyopathic dermatomyositis with normal muscle-enzyme, magnetic resonance scan and muscle biopsy. Muscle disease affects the proximal muscles, is generally symmetrical and symptoms are fatigue, weakness and sometimes myalgia. Proximal dysphagia reflects an involvement of striated muscle of the pharynx or proximal esophagus. Camptocormia reflects a severe involvement of paravertebral muscle. Other systemic features may be seen: pulmonary involvement (mostly interstitial pneumonitis and hypoventilation), arthralgias or arthritis, cardiac involvement, vasculatis and calcinosis particularly in children or adolescents with dermatomyositis. Malignant disease is associated with idiopathic inflammatory myopathies with a frequency of approximatively 10 to 15% in dermatomyositis and 5 to 10% in polymyositis and is strongly correlated with age, more than 50% of the patient over 65 years old were found to have a cancer. In the absence of malignant disease, the mainstay therapy for dermatomyositis and polymyositis is systemic corticosteroids (mostly 1mg/kg). In the lake of response or high dose dependance, intravenous immunoglobulins or immunosuppressive drugs like methotrexate or azathioprine may be discuss. Cyclophosphamide show some effectiveness in interstitial pneumonitis. Cyclosporin might be effective in children, less in adults. The efficacy of tacrolimus, mycophenolate mofetil, leflunomide and anti-TNF therapy need some prospective studies to determine if there are of value in idiopathic inflammatory myositis.

The group of idiopathic inflammatory myopathies encompasses polymyositis, dermatomyositis and inclusion body myositis. These diseases share the following features: progressive muscle weakness, an increase in serum creatine kinase activity and the presence of mononuclear cell infiltrates in the muscle biopsy. Polymyositis, dermatomyositis and inclusion body myositis are differentiated on the basis of the distribution of muscle weakness, and specific histopathological features. Many specialties may see these patients as the clinical presentation can vary widely and may be atypical, requiring further diagnostic procedures. A 40-year-old man with a heliotrope rash and periorbital oedema, but no muscle involvement, was diagnosed with dermatomyositis sine myositis. He was successfully treated with corticosteroids but died later of cardiac failure. A 72-year-old man with a pulmonary malignancy subsequently developed the clinical features of dermatomyositis. Steroid therapy diminished the complaints but he died of pulmonary embolism. A 54-year-old woman with the clinical features of inclusion body myositis did not have rimmed vacuoles in her muscle biopsy specimen and was initially erroneously diagnosed with polymyositis, for which she was treated with corticosteroids, but without beneficial effect.

Pulmonary sarcoidosis in association with dermatomyositis has rarely been reported. A 52-year-old woman was admitted for evaluation of a previously unrecognized bilateral hilar lymphadenopathy on a chest radiogram in August 1995. She had been receiving oral corticosteroids for dermatomyositis, which was confirmed by the typical skin rash and the myogenic changes on an electromyogram in 1977. She had no respiratory symptoms at the time of admission. Chest computed tomography showed hilar and mediastinal lymphadenopathy with reticular shadows in the peripheral lung parenchyma. A 67gallium-citrate scintigram apparently revealed accumulation in bilateral hilums. The tuberculin skin reaction was negative. Flowcytometry of bronchoalveolar lavage fluid indicated a CD4/CD8 ratio of 5.37. Thoracoscopic biopsy specimens sampled from the mediastinal lymph nodes and the lung demonstrated non-caseating granulomas. A definitive diagnosis of pulmonary sarcoidosis was made from these findings. The chest radiographic findings were spontaneously resolved after three years with no increase in the dosage of oral corticosteroids. It is well known that an abnormal immune response playa an important role in development of dermatomyositis and sarcoidosis. This case suggested close associations in both diseases.

A 44-year-old male was initially seen by dermatologists, who noted an erythematous rash on sun-exposed areas, the back, shoulders, and upper arms. There was associated muscle weakness and significant weight loss. Investigation revealed mildly raised aspartate and alanine transaminases but normal creatine kinase. Inflammatory indices and antinuclear antibodies (ANAs) were normal. Biopsy of the rash was reported as consistent with either dermatomyositis (DM) or acute lupus erythematosus. A diagnosis of DM was made, and prednisolone was given with improvement of the rash but deteriorating myopathy. The patient was referred to the rheumatology department, and further history revealed multiple vertebral fractures after falling from standing height; these had occurred six months prior to starting steroids. Besides smoking he had no other risk factors for osteoporosis. Examination showed normal muscle strength, no muscle tenderness, and no joint abnormality. Repeat muscle enzymes were normal, and ANAs were now 1 : 100, but dsDNA antibodies and extractable nuclear antigens were normal. Investigations for osteoporosis revealed a hypergonadotrophic hypogonadism picture. Further examination indicated scanty pubic and auxiliary hair, small testicles, and mild gynecomastia. He is married, though has no children of his own. The hormonal profile raised the possibility of Klinefelter's syndrome, which was subsequently confirmed with karyotyping of 47 XXY. Hypogonadism has been established as a cause of osteoporosis in males, and in this case would explain the occurrence of fractures in the absence of other major risk factors. Systemic lupus erythematosus has been recognized in association with Klinefelter's syndrome; in view of the normal muscle enzymes, his rash is most likely due to acute discoid lupus with androgen deficiency causing muscle weakness.

Human parvovirus B19 infection causes various clinical symptoms, such as rash, arthropathy, anemias and fetal death, but it can also remain asymptomatic. The arthropathies and anemias can become chronic for several years, not infrequently resembling autoimmune syndromes. B19 replicates only in red blood cell precursors of bone marrow or fetal liver, resulting in high-titred short-lived viremia, but viral DNA is detectable also in cells of several other types. Recently B19 DNA has been found, by very sensitive amplification tests, in certain tissues not only of symptomatic but also of healthy individuals for several years or decades after B19 infection. The mere presence of B19 DNA in these tissues of a symptomatic patient (e.g. joints in chronic arthritis or skin in dermatomyositis) thereby does not prove that the present disease is caused by B19. The diagnosis has to be verified by other innovative means. How and why viral DNA persists in the tissues of healthy individuals is under investigation.

Juvenile dermatomyositis is an uncommon autoimmune disease with classic heliotrope discoloration of the eyelids, erythematous skin rash of joints, and proximal muscle weakness. It is most frequently sporadic and only rarely familial. We present juvenile dermatomyositis in a 5-year-old brother and a 3 1/2-year-old sister, both are very responsive to corticosteroids. Familial dermatomyositis can occur in different family members, and even dermatomyositis and polymyositis can coexist in the same family.

The clinical features, outcome and complications of juvenile dermatomyositis were studied in a tertiary care hospital by retrospective analysis of case records. Nineteen patients were treated over an 11-year period. Median age at diagnosis was 12 years (2.5-16 years). Median duration of disease prior to diagnosis was 12 months (2-96 months). Proximal muscle weakness was seen in all 19 cases, neck muscle weakness in 14, pharyngeal muscle involvement in 5 and respiratory muscle involvement in 3 cases. Heliotrope rash was seen in 9 and Gottrons rash in 8 patients. Myocarditis and GI bleed were seen in 1 each while interstitial lung disease was seen in 2 patients. All except one patient received prednisolone. Methotrexate was used in 13 and azathioprine in 3 patients. Eight patients are in complete remission (CR), 8 partial remission and 2 patients had no response. Complications were calcinosis in 5, contractures in 2, TB in 4 and pyogenic infections in 4 patients. Juvenile dermatomyositis needs to be recognised early and treated aggressively to improve outcome.
