Differential Diagnosis for White Patch on Head of Children
- Single most likely diagnosis
- Pityriasis simplex (dandruff): This is a common condition in children characterized by a white, flaky patch on the scalp, often associated with mild redness and itching. It's usually benign and easily treatable.
- Other Likely diagnoses
- Seborrhoeic dermatitis: This condition can cause a white or yellowish patch on the scalp, face, or torso, often accompanied by redness and oiliness. It's relatively common in infants and children.
- Psoriasis: Although less common in children, psoriasis can cause white, scaly patches on the scalp, elbows, or knees. It's an autoimmune condition that requires medical attention.
- Tinea capitis (ringworm of the scalp): This fungal infection can cause patches of hair loss with white or black dots, redness, and itching. It's contagious and requires antifungal treatment.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Tinea corporis (ringworm of the body): While not usually deadly, if left untreated, it can lead to more severe infections or spread to other parts of the body.
- Impetigo: A highly contagious bacterial skin infection that can cause white or yellowish patches, often with redness and pus. If not treated, it can lead to more severe infections.
- Rare diagnoses
- Vitiligo: A condition that causes loss of skin pigment, resulting in white patches. It's relatively rare in children and can be associated with autoimmune disorders.
- Pityriasis alba: A mild, chronic skin condition that causes small, round, white patches on the face, often accompanied by mild redness and scaling. It's more common in children with atopic dermatitis.
- Scleroderma: A rare autoimmune disorder that can cause white, thickened skin patches, often accompanied by other systemic symptoms. It's extremely rare in children and requires immediate medical attention.
