Progression of Cutis Marmorata Following Initial Hyperbaric Therapy for Decompression Sickness.

We present a 33-year-old diver who developed decompression sickness after a 26-m dive. Initially improving with hyperbaric oxygen therapy, his lower abdomen rash unexpectedly progressed to diffuse cutis marmorata. He required multiple additional recompression sessions for complete resolution, highlighting the need for close monitoring.
