Prickly heat is a benign cutaneous manifestation due to the obstruction of the sweat ducts following excessive exposure to heat, humidity or hyperthermia. We report the case of a 70-year old diabetic female patient treated with insulin, hospitalized in the Intensive Care Unit due to acidocetosic coma secondary to pyelonephritis. The patient had diffuse clear vesicular lesions spread all over the body,(a) firm to palpation, on a healthy skin, suggesting miliaria crystallina. Miliaria crystallina is a benign cutaneous manifestation due to sweat retention secondary to obstruction of the sweat ducts. It is possible to distinguish between miliaria crystallina due to the obstruction in the stratum corneum, miliaria rubra due to the obstruction within the malpighian stratum and miliaria profunda due to an obstrusction in or below the dermoepidermal junction, depending on the level of obstruction. Miliaria crystallina heals spontaneously in a few hours giving rise to a desquamation, as occurred in our patient after regression of febrile syndrome.
痱子是在过度暴露于热、潮湿或体温过高后，因汗腺导管阻塞而出现的一种良性皮肤表现。我们报告了一例70岁的糖尿病女性患者，该患者使用胰岛素治疗，因肾盂肾炎继发酮症酸中毒昏迷而入住重症监护病房。患者全身有弥漫性清亮水疱性皮损，触之（a）质地坚实，位于正常皮肤上，提示晶痱。晶痱是由于汗腺导管阻塞继发汗液潴留引起的一种良性皮肤表现。根据阻塞的部位，可区分角质层阻塞引起的晶痱、马尔皮基层内阻塞引起的红痱和真皮表皮交界处或其下方阻塞引起的深痱。晶痱在数小时内可自愈并导致脱皮，就像我们的患者在发热综合征消退后出现的情况一样。
