Water Drops All Over the Skin: Miliaria Crystallina in an Adult Febrile Patient with Glioblastoma

Miliaria crystallina is a skin condition occurring due to the blockage of sweat ducts and the retention of sweat. It typically presents as fragile, clear fluid-filled vesicles on the skin surface. Humidity and heat are the main causative factors. The condition is self-limited and remission is promoted by keeping the affected areas cool, well-ventilated and dry. Miliaria crystallina is common in infants and children but rare in adults. We present a case of a febrile hospitalized adult patient who developed the characteristic rash, in order to raise awareness of clinicians and young doctors.
