Psoriasis and other diffuse inflammatory diseases of the scalp can cause a unique physical finding that we call the 'teepee sign' because the hair forms pyramidal tufts at regular intervals that resemble an American Indian encampment. A pathological mechanism for this finding is proposed, with the description of two cases in Air Force basic trainees, one of a severe seborrheic dermatitis and the other psoriasis. The significance with regard to physical qualification for entry into military service is discussed.
