This kind of lesion may occur in many types of cancer, including breast cancer, melanoma, and squamous cell carcinoma, and especially in advanced disease. The characteristic malodorous smell is caused by dimethyl trisulfide. [1] It is usually not a fungal infection but rather a neoplastic growth with necrosing portions.
Fibroblasts, the main cells that deposit granulation tissue, depend on oxygen to proliferate and lay down the new extracellular matrix. [7] In vascularisation, also called angiogenesis, endothelial cells quickly grow into the tissue from older, intact blood vessels. [8] These branch out in a systematic way, forming anastomoses with other vessels.
Malignant (or cancerous) pleural effusion is effusion where cancer cells are present. [11] It is usually classified as exudate. Types of exudates: serous, serosanguineous, sanguineous, hemorrhaging and purulent drainage. Serous: Clear straw colored liquid that drains from the wound. This is a normal part of the healing process.
What appears to be a chronic wound may also be a malignancy; for example, cancerous tissue can grow until blood cannot reach the cells and the tissue becomes an ulcer. [13] Cancer, especially squamous cell carcinoma, may also form as the result of chronic wounds, probably due to repetitive tissue damage that stimulates rapid cell proliferation ...
Granuloma with central necrosis in a lung of a person with tuberculosis: Note the Langhans-type giant cells (with many nuclei arranged in a horseshoe-like pattern at the edge of the cell) around the periphery of the granuloma. Langhans-type giant cells are seen in many types of granulomas and are not specific for tuberculosis.
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
Hundreds of young boys and girls covered with aluminum foil-like blankets next to chain link fences topped with barbed wire. The Sights, smells of holding cells for immigrant kids
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process. [5]
