Summary
Polymyositis and dermatomyositis are inflammatory muscle diseases linked to cancer. A rare case highlights the co-occurrence of dermatomyositis and acute myelocytic leukemia, with no disease onset delay.
Area of Science:
- Rheumatology
- Oncology
- Hematology
Background:
- Polymyositis (PM) and dermatomyositis (DM) are idiopathic inflammatory myopathies.
- These conditions are associated with an increased risk of various cancers, including ovarian, lung, pancreatic, breast, and stomach cancers.
- The association between PM/DM and hematological disorders, particularly acute myelocytic leukemia (AML), is exceptionally rare.
Observation:
- This case report details a patient presenting with dermatomyositis (DM).
- The patient was diagnosed with acute myelocytic leukemia (AML) upon admission.
- This represents the second reported instance of concurrent DM and AML without a latent period.
Findings:
- The co-occurrence of dermatomyositis and acute myelocytic leukemia is extremely rare.
- This case is only the second documented instance of DM and AML presenting simultaneously.
- The absence of a latent period between the onset of DM and AML diagnosis is noteworthy.
Implications:
- This case underscores the importance of considering hematological malignancies in patients with inflammatory myopathies.
- Further research is warranted to understand the specific mechanisms linking DM/PM and AML.
- Early diagnosis and management of both conditions may improve patient outcomes.

01:21Myocarditis I: Introduction
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
