why do cysts smell bad
From traumatized skin to hair follicles âÅ¡ thatâs the cause of sebaceous cyst. Pus is the result of fluid remains of liquefactive necrosis of tissues. It is usually pale yellow to yellow green and sometimes whitish. Bacterial infections are the most often cause of pus-filled cysts like acne. Because pus is formed through the accumulation of dead tissues, it causes the discharge to smell unpleasant.
