Does anal itching in adults indicate a pinworm infection?

Anal itching in adults may be associated with pinworm infection. Pinworms lay eggs around the anus, irritating the surrounding skin and causing pruritus. Anal itching may also result from perianal eczema, which can manifest as varying numbers of small vesicles or papules around the anus, accompanied by moist skin and pruritus. Perianal pruritus syndrome is another potential cause of anal itching and may be related to certain surgical conditions. If anal itching is pronounced, medical evaluation at a hospital is recommended for proper diagnosis and targeted treatment.
