We describe a case of juvenile dermatomyositis associated with hepatocarcinoma.A 14-year-old boy with a weight loss of 15 kg over a three-month period presented with clinical signs of dermatomyositis, including typical edematous rash, muscular weakness. About half of children with JDMS also have pain in their muscles.Other symptoms may include irritability, weight loss, and mouth ulcers.


The life expectancy of person with dermatomyositis depends on the stages of the disease, physical state and medical condition of the patient. According to statistics of 50 years ago, about 20% of patients with dermatomyositis developed uremia within 10 years, which is the main cause of dermatomyositis.

Although certain clinical features are common to both JDM and adult-onset dermatomyositis, the frequency of these features differs significantly, suggesting that the age of patients at the onset of disease affects disease processes. 2020-11-30 · In juvenile dermatomyositis (JDM), the clinical features are usually insidious. Muscle weakness is the main reason for consultation, usually accompanied by systemic signs like asthenia, anorexia, irritability, pain, fever, and deterioration of one's general condition. At its onset, Juvenile dermatomyositis (JDM) is primarily characterized by symptoms like fever ranging from 101-104º, skin rash, muscle weakness, stiff and swollen joints, contractures, ulcers, calcium deposits in the body, redness and dryness of skin, poor appetite, weight loss and gastrointestinal problems. Juvenile dermatomyositis (JDM) is an inflammatory myopathy, of which etiology is probably autoimmune, with an onset before the age of 18 years. It differs from the adult disease by the higher incidence of vasculopathy, proliferation of the intima of small vessels, thrombosis or infarctions,1 and by the smaller frequency of autoantibodies.

Juvenile dermatomyositis is a rare autoimmune disorder in which the immune system attacks blood vessels throughout the body (called vasculopathy), causing muscle inflammation (known as myositis).

Juvenile dermatomyositis (JDM) is a disease in children that causes skin rash (dermato) and muscle inflammation (myositis). It results in weak muscles.

Juvenile dermatomyositis is a relatively rare, multisystem disease characterized by a nonsuppurative myositis which causes symmetrical weakness, rash and vasculitis; this last can affect the gastrointestinal tract and the myocardium.

The disease often begins with nonspecific, general symptoms (such as fever, fatigue and muscle weakness). 2017-02-01 2021-02-26 Registries and biobanks for juvenile dermatomyositis (JDM) have generated statistical power to help understand pathogenesis and determine treatment and long-term outcomes in this rare and heterogeneous disease. Genotype, autoantibodies, muscle histology and early clinical features may predict prognosis and guide personalised treatment. 2020-02-24 In dermatomyositis, the small blood vessels in muscle (myositis) and skin (dermatitis) are affected. This inflammation leads to the problems that your child may have experienced such as muscle weakness, muscle pain and skin rashes on the face, eyelids, knuckles, knees and elbows.
