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.
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.
Healthy cells maintain a balance called homeostasis, constantly adjusting to various stressors and stimuli from their environment. When a cell can't adapt properly to these changes, it suffers a reversible injury. However, if the cell can't return to its normal state and continues to be exposed to stress or damage, the injury becomes irreversible.
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 ...
The specific name, perfringens, is derived from the Latin per (meaning "through") and frango ("burst"), referring to the disruption of tissue that occurs during gas gangrene. [7] Gas gangrene is caused by alpha toxin, or α-toxin, that embeds itself into the plasma membrane of cells and disrupts normal cellular function by altering membrane ...
Scratch wound healing assay experiment of rhabdomyosarcoma, a cancer cell line. A wound healing assay is a laboratory technique used to study cell migration and cell–cell interaction. This is also called a scratch assay because it is done by making a scratch on a cell monolayer and capturing images at regular intervals by time lapse microscope.

The final structure of the abscess is an abscess wall, or capsule, that is formed by the adjacent healthy cells in an attempt to keep the pus from infecting neighboring structures. However, such encapsulation tends to prevent immune cells from attacking bacteria in the pus, or from reaching the causative organism or foreign object. [26]
