Facial Ecchymosis Following a Dive with the U.S. Navy Mk I Diver's Mask

摘要

A diver presented with facial ecchymosis in the distribution of his mask following a dive to 43 fsw using the U.S. Navy MK I mask. There was no apparent problem during the dive. He had taken two or three aspirin tablets 1 week prior to the dive. Hematologic studies were notable for a bleeding time of 8 min and abnormal platelet aggregation. After 2 weeks free of medication, the subject's bleeding time was 5 min and platelet aggregation studies were normal. Differential diagnosis of skin lesions following diving is discussed. Face mask squeeze, rare with the MK I mask, appears in this case to be related to abnormal platelet function caused by previous aspirin ingestion. (aw)
