    A malignant tumor is a group of diseased cells defined by one of three characteristics: uncontrolled growth, invasion and damage of healthy cells, or metastasizing (spreading) to other organs of the body. They differ from benign tumors, which do not spread or affect other areas of the body. A malignant tumor has irregular borders and grows faster than a benign tumor. A malignant tumor can also spread to other parts of your body.

    Carcinomas are cancers that develop in epithelial cells, which cover the internal organs and outer surfaces of your body. Sarcomas are cancers that develop in mesenchymal cells, which make up both your bones and soft tissues, such as muscles, tendons, and blood vessels.
    The main difference between carcinomas and sarcomas is where they originate.

    Carcinomas: Carcinomas, which originate in epithelial cells, tend to affect your skin or mucous membranes. The five most common types of carcinoma include:
    Adenocarcinoma. This type of carcinoma affects organs that produce fluids or mucous, such as the breasts or prostate.
    Basal cell carcinoma. This type affects the cells that form the foundation of your outer-most layer of skin. This is the most common type of skin cancer.
    Squamous cell carcinoma. This type affects the cells above the basal cells in your skin and is the second most common type of skin cancer.
    Transitional cell carcinoma. This type affects transitional cells in your urinary tract, including your bladder, kidneys, and ureter.

    Sarcomas: Sarcomas are tumors that develop from soft tissue cells called mesenchymal cells. Mesenchymal cells help form and support many vital organs and tissues, such as:

    bones
    blood vessels
    cartilage
    nerves
    muscles
    fat
    joints
    tendons
    ligaments
    While rare, there are over 75 types of sarcomas. They can occur anywhere, but are most common in the abdomen, arms, or legs.

    The most common types of sarcoma include:

    Undifferentiated pleomorphic sarcoma. This type of sarcoma involves soft tissue and bone cells at the same time.
    Leiomyosarcoma. This type of sarcoma involves smooth muscle cells that line your blood vessels, gastrointestinal tract, and uterus.
    Osteosarcoma. This type of sarcoma involves bone cells.
    Liposarcoma. This type of sarcoma involves fat cells.

    Carcinomas and sarcomas also differ in how common they are. While carcinomas are more common, sarcomas are rarer.

    Carcinomas
    About 90 percentTrusted Source of all cancers cases involve a type of carcinoma.

    Carcinomas affect people of all ages, genders, and ethnicities. There are different risk factors for different carcinomas. Some of these risk factors include:

    smoking
    excessive alcohol consumption
    long-term exposure to ultraviolet light from the sun or tanning beds
    long-term exposure to heavily polluted air
    obesity
    inactivity or lack of physical fitness
    being fair skinned
    Sarcomas
    According to Cancer Research UK, sarcomas account for less than 1 percent of cancers diagnosed each year.

    Like carcinomas, sarcomas can affect anyone. However, certain medical conditions, environmental influences, and lifestyle habits can increase your risk of developing a type of sarcoma.

    Medical risk factors for sarcomas include:

    tubular sclerosis (Bourneville disease)
    retinoblastoma
    neurofibromatosis type 1 (Von Recklinghausen’s disease)
    familial adenomatous polyposis (Gardner’s syndrome)
    nevoid basal cell carcinoma syndrome (Gorlin syndrome)
    Werner syndrome
    Li-Fraumeni syndrome
    Environmental and lifestyle risk factors for sarcoma include:

    exposure to harmful or toxic chemicals, especially arsenic, thorium dioxide, and vinyl chloride
    exposure to radiation during cancer therapy
    exposure to repeated radiation from continual or frequent diagnostic imaging scans, like X-rays
    In addition, some types of sarcomas are more common in certain age groups.

    Types of sarcomas that are more common in infants, children, and young adults include:

    rhabdomyosarcoma
    osteosarcoma
    alveolar soft-part sarcoma
    desmoplastic small round cell tumor
    epithelioid sarcoma
    synovial sarcoma
    infantile fibrosarcoma
    Types of sarcomas that are more common in adults include:

    adult fibrosarcoma
    fibromyxoid sarcoma, low-grade
    liposarcomas
    myxofibrosarcomas, low-grade

    Metastases of neoplasmic cells can occur in three ways: 1. They can grow directly into the tissue surrounding the tumor. 2. Cancer cells can travel through your bloodstream to distant locations in your body. 3. Cancer cells can travel through your lymph system to nearby or distant lymph nodes.

    Metastasis is a pathogenic agent's spread from an initial or primary site to a different or secondary site within the host's body; the term is typically used when referring to metastasis by a cancerous tumor.

    Neoplasms can be classified based on their histological type, which refers to the type of tissue in which the cancer originates. The international standard for the classification and nomenclature of histologies is the International Classification of Diseases for Oncology, Third Edition (ICD-O-3).

    From a histological standpoint, there are hundreds of different cancers, which are grouped into six major categories:
    1. Carcinoma,
    2. Sarcoma,
    3. Myeloma,
    4. Leukemia,
    5. Lymphoma, and
    6. Mixed types.

    Carcinoma refers to a malignant neoplasm of epithelial origin or cancer of the internal or external lining of the body. Carcinomas account for 80 to 90 percent of all cancer cases. Sarcoma refers to cancer that originates in supportive and connective tissues such as bones, tendons, cartilage, muscle, and fat. Myeloma is a cancer that originates in the plasma cells of bone marrow. Leukemia is a cancer of the bone marrow (the site of blood cell production).

    Neoplasms can also be classified based on their behavior. According to the International Classification of Diseases (ICD-10), neoplasms are classified into four main groups:
    1. Benign neoplasms,
    2. In situ neoplasms,
    3. Malignant neoplasms, and
    4. Neoplasms of uncertain or unknown behavior.

    Benign neoplasms are non-cancerous growths that do not spread to other parts of the body and are not life-threatening. In situ, neoplasms are abnormal growths that remain in their original location and have not spread to other parts of the body. Malignant neoplasms, also known as cancers, are abnormal growths that can invade and destroy nearby tissue and spread to other parts of the body. Neoplasms of uncertain or unknown behavior are growths for which it is not yet known whether they are benign or malignant.

    Dry gangrene is a type of gangrene that occurs when the blood supply to the tissue is cut off, leading to prolonged ischemia (lack of oxygen) or inadequate oxygenation. This can be due to peripheral artery disease or acute limb ischemia. As a result, people with atherosclerosis, high cholesterol, diabetes, and smokers commonly have dry gangrene. The limited oxygen in the ischemic limb limits putrefaction and bacteria fail to survive.

    Gas gangrene, also called myonecrosis, is a type of wet gangrene that is caused predominantly by **Clostridium perfringens** bacteria. The pathogenesis of gas gangrene involves the entry of bacteria into an ischemic wound, which provides anaerobic conditions for the bacteria due to a lack of blood supply. The bacteria then multiply in the dead tissue and produce exotoxins such as alpha toxin (lecithinase), which lyses erythrocytes, platelets, leukocytes, endothelial cells, fibroblasts, and muscle cells.

    The local effects of gas gangrene include necrosis of muscle and subcutaneous fat, thrombosis of blood vessels, marked edema which further compromises blood supply to the region, and gas production by fermentation of glucose. Systemic effects include hemolysis and cardiovascular abnormalities. The exotoxins further create more anaerobic conditions suitable for clostridium to proliferate and spread. Death may occur due to septic shock and unintentionally damaging effects of the immune response.
