Vesicle vs. Papule — What's the Difference?

Key Differences
Vesicles are characterized by their fluid content, typically clear or translucent, which can be serum, or other bodily fluids. Whereas papules are distinctly solid to the touch, lacking any fluid content and are often associated with conditions like acne or dermatitis.
Vesicles are usually less than 5mm in diameter, appearing as tiny blisters on the skin. On the other hand, papules can also be small, usually the same size but are recognized by their raised and firm nature.
The formation of vesicles often indicates conditions such as chickenpox, herpes, or allergic reactions, where fluid accumulation is part of the body's response to infection or irritation. Whereas papules are commonly formed due to inflammation or a clogged pore in the skin, marking disorders like eczema and rosacea.
Vesicles may rupture or resolve on their own, leading to crusting or scaling as they heal. In contrast, papules may persist for longer periods and can become inflamed or turn into pustules if infected.
Diagnosis and treatment for vesicles typically focus on the underlying cause and managing the fluid buildup. On the other hand, treatment for papules might involve topical or systemic medications aimed at reducing inflammation and preventing progression.
