Differential Diagnosis for White Skin on the Penis
- Single most likely diagnosis
- Lichen sclerosus: This condition is characterized by white, patchy skin that can become thin and wrinkled, often affecting the genital area. It's a common cause of white skin on the penis and can be managed with topical corticosteroids.
- Other Likely diagnoses
- Vitiligo: An autoimmune condition that causes loss of skin pigment, leading to white patches. While it can occur anywhere on the body, it's less common on the penis compared to other areas.
- Eczema (atopic dermatitis): Can cause white, scaly patches due to inflammation and skin dryness. Genital eczema is less common but can occur.
- Psoriasis: Although less common in the genital area, psoriasis can cause white, scaly patches due to an overactive immune response.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Squamous cell carcinoma: A type of skin cancer that can present as white or discolored patches. Early detection is crucial for effective treatment.
- Extramammary Paget's disease: A rare skin cancer that can appear as white or red patches in the genital area, requiring prompt medical attention.
- Rare diagnoses
- Scleroderma: A chronic autoimmune disease that can cause skin thickening and hardening, potentially leading to white, tight skin on the penis.
- Pityriasis alba: A mild skin condition causing small, round, white patches due to mild eczema or dry skin, more common in children but can occur in adults.
- Leukoplakia: A condition characterized by white patches on mucous membranes, which can rarely occur on the penis and may be associated with an increased risk of cancer.
