The lesions of intra-anal warts are often small and flat, but in warm, moist areas they are often filiform or papillomatous. The first is a small reddish papule, which gradually increases in size and fuses with each other, with an uneven surface, moist and soft, papillomatous, cockle-like, straw-like, myxoid or cauliflower-like protrusions, red or dirty gray, often with a tip at the root, and prone to erosion and oozing and bleeding.
