Gangrene is gotten from the Latin word gangreana and Greek word gangraina both of which mean sanitization of tissues. Gangrene is brought on because of absence of blood supply to the tissues. A condition where the tissue kicks the bucket and blood supply hindered is called rot. Despite the fact that the most well-known zones that are influenced are the furthest points, it can likewise influence the inside organs and muscles.

Autosomal latent familial adenomatous polyposis or MYH related polyposis is mellow and shows just when both the folks are transporters.

There are at least five types of gangrene:
Dry gangrene: This is also called senile gangrene affecting older patients. It evolves at the distal part of the limb and extends to the toes and feet. This mainly occurs due to arterial occlusion.
Wet gangrene: Wet gangrene affects tissues that are naturally moist. Organs that are affected are lungs, cervix, mouth, bowel and vulva. Bed sores are a type of wet gangrene and can affect the sacrum, heels and buttocks even if they are not wet.
Gas gangrene: Gas gangrene is caused by Clostridium perfringens bacteria which is a bacterial infection producing gas within the tissues.
Internal gangrene: When gangrene affects and infects the internal organs of the body such as the colon or the appendix, it is called internal gangrene.
Fournier’s gangrene: Fournier’s gangrene is named after a French venereologist Jean Alfred Fournier. It is a necrotizing infection of the perineum.

Arteriogram: This is done to check for blockages in the blood vessels.

Blood tests: A WBC count is taken which may be elevated.

CT scan: This is done to scan the internal organs for abnormalities.

Culture tests: A tissue culture or fluid from the wounds is collected to check for any bacterial infection.

Biopsy: A biopsy is done to examine the tissue under the microscope to look for malignancies.
