Nicole Red blood pimples on the testicular skin may be related to factors such as folliculitis, allergic dermatitis, herpes zoster, scrotal eczema, molluscum contagiosum, etc. If necessary, you need to seek medical treatment for a clear diagnosis.
1. Folliculitis
Folliculitis is a common cause of red blood pimples on testicular skin, mainly caused by bacterial infection of hair follicles. Local manifestations include red papules or pustules, which may be accompanied by pain or itching. Patients need to keep the perineum clean and dry and avoid scratching. Physicians may recommend topical antibiotic ointments such as mupirocin ointment, fusidic acid cream, or compound polymyxin B ointment to control infection.
2. Atopic dermatitis
Contact with allergens such as laundry detergent and underwear materials may cause allergic reactions on the scrotal skin, with red papules and severe itching. Patients should investigate and avoid contact with allergens, and cold compresses can be used to relieve symptoms. Doctors may prescribe weak hormone ointments such as desonide cream and hydrocortisone butyrate cream, or oral antihistamines such as loratadine tablets.
3. Herpes zoster
Reactivation of the varicella-zoster virus may cause shingles in the genital area, which may appear as clusters of blisters or blood blisters with neuralgia. Antiviral drugs such as acyclovir cream and famciclovir tablets can be used in the early stage. Gabapentin capsules can be added when the pain is severe. The disease is contagious and patients need to avoid close contact with others.
4. Scrotal eczema
Scrotal eczema manifests as erythema, papules with a tendency to ooze, and is mostly related to local excessive sweating and friction irritation. Patients should wear loose-fitting cotton underwear to reduce scratching. Physicians may recommend the use of calcineurin inhibitors such as tacrolimus ointment and pimecrolimus cream, or short-term use of halomethasone cream to control acute attacks.
5. Molluscum contagiosum
Molluscum contagiosum is caused by the pox virus and appears as skin-colored or red hemispherical papules with an umbilical depression in the center. It is contagious through contact, so avoid squeezing yourself. Cryotherapy or topical imiquimod cream can be used clinically. Stubborn skin lesions may require curettage.
Pay attention to the cleaning of the perineum every day, choose breathable and sweat-absorbent underwear materials, and avoid using irritating lotions. If the rash persists, expands in area, or develops systemic symptoms such as fever, you should see a dermatologist or urologist in time. It is not recommended to self-medicate before diagnosis, especially to avoid abusing hormonal ointments to aggravate the condition. At the same time, attention needs to be paid to the risk of cross-infection between partners, and joint diagnosis and treatment is required when necessary.
