Based on the symptoms you described, there may be an infection present such as genital warts or pseudowarts, and a differential diagnosis is needed.
Pseudowarts clinically manifest as papules 1-2 millimeters in size, light red in color, clustered but not fused; they have a smooth surface resembling fish eggs or velvet, and feel granular to the touch. Generally, there are no noticeable symptoms or only mild itching, and it is easy to confuse with genital warts clinically.
Genital warts initially appear as moist papules that are light red or dirty gray, quickly forming wart-like proliferations of varying sizes which may fuse together, resembling cauliflower or rooster combs, sometimes with secretions and a foul odor. We recommend that you visit our hospital's reproductive infection specialist department for examination and diagnosis.
