It can be distinguished that the surface of pearl rash is round and smooth, and some papules are hairy or filamentous. Most papules do not fuse with each other, and they are densely arranged in one or more rows, which are obvious on the back of the glans penis and can partially or completely surround the glans penis. The damaged color is mostly pearly white, a few are reddish, and some may be slightly red and swollen. There was no tenderness or ulceration, and the patient had no conscious symptoms.

The lesions of condyloma acuminatum were small reddish papules at first, and then gradually increased, distributed singly or in clusters, moist and soft, with uneven surface, nipple-like, cockscomb-like or cauliflower-like protrusions. Red or dirty gray. The roots often have pedicels, and are prone to erosion and exudation, and it is easy to bleed when touched. Pustuous secretions often stagnate between skin lesions and cracks, causing stench and secondary infection due to scratching. The disease often has no conscious symptoms, and some patients may have foreign body sensation, pain, itching or sexual pain. Condyloma acuminatum in rectum can cause pain, bloody stool, and heavy feeling after urgency.

The most direct way is to go to the hospital to do vinegar white experiment. Only condyloma acuminatum will react to vinegar white experiment, but pearl rash will not.

Hope to adopt thank you.
