Possible conditions for lumps appearing on the scrotum:

1. Folliculitis: The hair follicles on the scrotum may become infected with bacteria, leading to folliculitis. This usually presents as red pimples, possibly accompanied by pain or itching.

2. Scrotal eczema: This is an allergic inflammatory condition, in which small white pimples or small blisters may appear on the scrotal skin, accompanied by diffuse redness and swelling, and severe itching. It is usually related to local irritation, allergies, and other factors.

3. Sebaceous cyst: A cyst formed by the accumulation of sebaceous gland secretions under the skin, which is usually painless, but may become infected and turn red and swollen.

4. Viral infection: Sexually transmitted diseases such as genital herpes or genital warts may form small lumps or ulcers on the scrotum or around the genitals.

5. Parasitic infection: For example, pubic lice. Although not a lump, it can cause intense itching, sometimes with small red spots or pimples visible.

6. Allergic reaction: Medications, cosmetics, or detergents may cause an allergic reaction on the scrotal skin, resulting in itching, redness and swelling, and pimples.
