Differential Diagnosis for a Slightly Raised and White Lesion
- Single most likely diagnosis:
- Milia: These are small, white, raised bumps that typically appear on the nose and cheeks. They are very common and usually harmless, making them a likely diagnosis for a slightly raised and white lesion.
- Other Likely diagnoses:
- Fordyce spots: These are small, white or yellowish bumps on the lips, inside of the cheeks, and sometimes the genital area. They are benign and very common, especially in adults.
- Keratosis pilaris: This condition causes small, rough, white or light-colored bumps on the skin, often on the arms, legs, buttocks, and cheeks. It's a common condition and can be associated with dry skin.
- Seborrheic keratosis: While often pigmented, some seborrheic keratoses can appear white or light-colored. They are benign growths that are very common in older adults.
- Do Not Miss diagnoses:
- Basal cell carcinoma: Although less common, some basal cell carcinomas can appear as pale or white lesions. Given the potential severity of skin cancer, it's crucial not to miss this diagnosis.
- Squamous cell carcinoma: Similar to basal cell carcinoma, squamous cell carcinoma can sometimes present as a firm, white lesion. Early detection is key for effective treatment.
- Rare diagnoses:
- Lichen planus: This is an inflammatory condition that can affect the skin and mucous membranes, sometimes causing white, raised lesions. It's less common than other conditions listed here but should be considered in the differential diagnosis.
- Leukoplakia: This condition appears as a white patch or plaque in the oral mucosa and can sometimes be raised. It's associated with an increased risk of oral cancer, making it an important consideration, although it's less likely given the description of being "slightly raised."
