A 34-year-old man presented with a 6-year history of a recurrent pruritic eruption on the scalp. He was initially treated for seborrheic dermatitis without notable improvement. He later developed polydipsia and polyuria and was diagnosed with diabetes insipidus. After the patient's correct diagnosis was made after a biopsy of the scalp, he was treated with scalp radiation with resolution of the lesions. Two years later, his scalp eruption recurred. It initially started on the left frontoparietal area and then progressed to involve the other side of the scalp.
