Histiocytic sarcom is a rare and aggressive malignant tumor of the histiocyte cell line, which is part of the mononuclear phagocyte system. It is characterized by the proliferation of neoplastic histiocytes that have features of both macrophages and dendritic cells. The tumor can occur in various organs and tissues, including the lymph nodes, spleen, liver, skin, soft tissue, and bone. Histiocytic sarcom is different from other histiocytic disorders such as Langerhans cell histiocytosis and malignant histiocytosis, and it has a poor prognosis with a high rate of recurrence and metastasis.

"Experimental sarcoma" refers to a type of cancer that is being studied in clinical trials or research experiments. Sarcomas are rare cancers that develop in the body's connective tissues, such as muscles, tendons, cartilage, and bones. In an experimental setting, researchers may be testing new treatments, drugs, or therapies to determine their safety and effectiveness in treating sarcoma. This could include investigating novel surgical techniques, radiation therapy approaches, or immunotherapies, among others. It is important to note that while these treatments may show promise in the lab or early-stage clinical trials, they have not yet been proven to be safe and effective in larger patient populations.
Ytantigener som uttrycks på myeloidceller tillhörande granulocyt-monocyt-histiocytserien under differentieringen. Deras reaktioner i normala och elakartade myelomonocytiska celler kan användas för att identifiera och klassificera leukemier och lymfom hos människa.
Här avses tamhund, Canis familiaris, med omkring 400 raser och tillhörande rovdjursfamiljen Canidae. De finns överallt i världen och lever tillsammans med människor.
I en enkel mening kan muramider definieras som en typ av karbohydratmolekyler som är en viktig bestanddel i cellväggarna hos gram-positiva bakterier. Muramider katalyserar celldelningen under bakteriers tillväxt och reproduktion, och de utgör därför ett intressant mål för flera antibiotika som vancomycin och penicillin. Dessa läkemedel fungerar genom att hämma förmågan hos muramiderna att bygga upp cellväggen korrekt, vilket leder till celldöd hos bakterierna.
Ewing sarcoma is a type of cancerous tumor that usually develops in the bones or soft tissues, such as muscles and fat, surrounding the bones. It primarily affects children and young adults, with peak incidence between the ages of 10 and 20. Ewing sarcoma is characterized by specific genetic changes involving chromosomes 11 and 22, leading to the formation of a fusion protein that drives tumor growth. The most common symptoms include pain, swelling, and redness at the site of the tumor. Early diagnosis and prompt treatment with a combination of chemotherapy, surgery, and/or radiation therapy are crucial for improving outcomes and survival rates in patients with Ewing sarcoma.
Synovial sarcom, also known as synovial cell sarcoma, is a rare type of soft tissue cancer that typically develops in the extremities, such as the arm or leg, near joints like the knee, wrist, ankle or shoulder. Despite its name, it does not arise from the synovial tissue that lines the joints. The tumor usually forms in the soft tissues around the joints, but can also occur in the lungs or other areas of the body. It primarily affects young adults and can have varying degrees of aggressiveness. Early diagnosis and treatment are crucial for better prognosis.
Kaposi's sarkom (KS) är en blodkärlsrelaterad cancer som orsakas av ett virus kallat humant herpesvirus 8 (HHV-8). KS kan manifestera sig som röda, lila eller bruna fläckar, knutor eller sår på huden, slemhinnor eller inre organ. Det finns fyra olika typer av KS: klassisk, endemisk, epidemisk och immunsuppressivt relaterad. Den epidemiska formen är den som oftast ses i samband med HIV/AIDS.
