Mottled, Blanching Skin Changes After Aggressive Diving.

The initial livedo skin changes of cutis marmorata, also known as cutaneous decompression sickness (DCS), are transient in nature. Accordingly, early images of violaceous skin changes with variegated, marbled, or mottled appearance are rare, whereas later images of deep, erythematous, or violaceous skin changes are readily available. This case presents the opportunity to view the early skin changes characteristic of cutaneous DCS, which would likely manifest at Level I care in the setting of a diving injury during Special Operations missions in austere environments.
