What type of fluid is commonly found in lesions associated with folliculitis?

In lesions associated with folliculitis, the fluid commonly present is pus. Folliculitis is inflammation of the hair follicles, which can be caused by bacterial infections, leading to the accumulation of pus. This pus is composed of white blood cells, dead skin cells, and bacteria, which results from the body's inflammatory response to the infection.

In contrast, serum is typically found in other types of lesions or wounds, whereas clear fluid may suggest a different type of inflammatory or allergic response. Blood presence would indicate a more severe condition or trauma rather than the mild infection associated with folliculitis. Therefore, recognizing pus as the characteristic fluid in folliculitis lesions underscores its infectious nature and the body's response to such infections.
