• freudenthal syndrome
• accidental intramuscular injection
• gangrene of the hand.

analysis of 32 cases of accidental injection of oily suspension (in most cases) into the deltoid muscle is reported. pain and local ulcers characterized the accidents. in many cases, simultaneous ischemic disorders were observed in the scapular and pectoral regions and especially in the end of the upper limb. it is presumed that this complex lesion was caused by 1) the harmful action of the medication on nervous terminations, soft and perivascular tissues; and/or 2) occasional entrance of the substance into blood vessels, causing embolism and/or thrombotic endothelitis; and/or 3) vasomotor phenomena. hand injuries were generally more severe than injuries in the deltoid region, with occasional spontaneous or surgical loss of fingers. clinical statuses were similar, though some lesions had features, which allowed identification of peculiar physiopathogenic mechanisms, with conceptual and therapeutic significance.
