Differential Diagnosis for Tiny White Bumps on Genital Area
Single Most Likely Diagnosis
- Fordyce spots: These are small, white or yellowish bumps that can appear on the genitals, including the penis and testicles. They are caused by the abnormal presence of sebaceous glands in the skin and are generally harmless.
Other Likely Diagnoses
- Pearly penile papules: These are small, white bumps that appear on the edge of the penis. They are a common and benign condition, often mistaken for genital warts or other sexually transmitted infections.
- Seborrheic keratoses: These are benign growths that can appear as white bumps on the skin, including the genital area. They are more common with age and are not typically a cause for concern.
- Molluscum contagiosum: This is a viral infection that causes small, white or flesh-colored bumps on the skin. It is contagious and can be spread through skin-to-skin contact.
Do Not Miss Diagnoses
- Genital warts (HPV): While often associated with larger, more noticeable lesions, some strains of human papillomavirus (HPV) can cause smaller, whiter bumps. Given the potential for HPV to lead to serious health issues, including cancer, it's crucial not to miss this diagnosis.
- Syphilis: In its secondary stage, syphilis can cause a wide range of skin symptoms, including small, white bumps. Syphilis is a serious infection that can lead to significant health problems if not treated.
Rare Diagnoses
- Lichen nitidus: A rare skin condition characterized by tiny, shiny, flat-topped bumps that can appear on the genitals among other areas. It's usually harmless but can be itchy.
- Scleroderma: A chronic disease characterized by the deposition of collagen, leading to hardening and tightening of skin and connective tissues. It can rarely present with small, white bumps in the genital area, among other symptoms.
