A 56 years old, with a history of type 2 diabetes, was admitted in the intensive care unit for the management of stage E pancreatitis. She was febrile, unconscious, ventilated and had a gastric feeding tube. She was put on broad spectrum antibiotic therapy for extensive extrapancreatic fluid collectioSns. As her fever began to break, her skin erupted with widespread vesicles. We found clear, waterdrop-like vesicles, 1–3 mm in size, scattered across her chest and shoulders, crossing dermatomes and sparing mucosae. These findings were consistent with miliaria crystallina. Unfortunately, the patient died few days later from septic shock.

Miliaria crystallina is a transient occlusive sweat gland disorder resulting in the leakage and retention of sweat into the epidermis [1]. Small 1- to 2-mm flaccid (MC) vesicles that rupture easily characterize MC. This skin condition resolves spontaneously and requires no treatment [2].
