We report an 80-year-old woman with a bilateral mutilating acro-osteolysis of the fingers progressing over a period of 3 years. As the patient refused nerve or muscle biopsies, our diagnosis of acropathia ulcero-mutilans acquisita or Bureau-Barrière syndrome, characterized by osteolysis, remains hypothetical. Sporadic sensory mutilating acropathy of the upper limbs is rare, and we discuss the differential diagnosis.
BACKGROUND: Tramadol chlorhydrate (Topalgic) is a powerful analgesic recently introduced in France where its use has spread rapidly. We report a case where this drug induced a maculopapulous toxic skin reaction with secondary erythrodermia. CASE REPORT: A 47-year-old man was treated for lower back pain with tramadol chlorhydrate (50 mg b.i.d.). Otherwise, he was in good general health and was taking no other medications. Shortly after beginning the treatment, he developed a highly pruriginous maculopapulous eruption involving the entire skin surface, hyperthermia and general degradation. There was no skin exfoliation, mucosal involvement nor nodal enlargement. Tramadol was withdrawn and the patient was given corticosteroid therapy. Secondary erythrodermia developed after termination of the corticosteroids. The lesions regressed after tramadol withdrawal. DISCUSSION: Tramadol-induced skin reactions are uncommon and usually benign. In our case, the delay from onset of tramadol and the development of the maculopapulous eruption was very short (four days). The patient was taking no other medication. We hypothesize that the patient had been sensitized by cross-reaction with another compound and recall the fundamental aspects of tramadol and opiate drugs.
BACKGROUND: Leg ulcres can be seen as manifestations of antiphospholipid syndromes but their pathogenic relationship with vascular thrombotic events secondary to antiphospholipid antibodies remains to be defined with precision. A significant association between anticardiolipin antibodies and venous leg ulcers has been described. We conducted this study to determine whether such an association is found in venous ulcers and if it could also be present in cases involving the arterial and/or arteriolar circulation. PATIENTS AND METHODS: From December 1995 to March 1997, 48 patients with leg ulcers involving venous (27 cases), arteriovenous (9 cases) or arteriolar (12 cases) circulations were admitted. The etiologic diagnosis was based on clinical presentation and duplex Doppler findings examining the superficial and deep venous and arterial circuits. Antiphospholipid antibodies were searched for in all cases: VDRL, ELISA for IgG and IgM antiphospholipid antibodies, antiprothrombinase circulating anticoagulant. RESULTS: Circulating anticoagulants were found in 22 of the 48 patients (46%): 12/27 (44%) involved venous leg ulcers (anticardiolipin antibodies, 5 cases; circulating anticoagulants, 4 cases; both, 2 cases); 1/9 involved arteriovenous ulcers (anticardiolipin antibodies, 5 cases); 9/12 involved arteriolar ulcers (anticardiolipin antibodies, 3 cases; circulating anticoagulants, 6 cases; both, 3 cases). Seven of the 9 patients also had severe arteritis. A past history of venous thrombosis was found in 3 cases with venous ulcers and antiphospholipid antibodies. One patient among the 5 with arteriolar ulcers had a past history of arterial thrombosis. DISCUSSION: Our cohort is too small for a formal conclusion but underlines two points: 1. antiphospholipid antibodies can be associated with venous ulcers independently of thrombosis history. The hypothesis that leukocyte stasis and endothelial cell activation causes an immune reaction implicating antiphospholipid antibodies has been put forward. The usefulness of an antiaggregate treatment or an anticoagulant treatment should be discussed, 2. The possible association between arteriolar ulcers and antiphospholipid antibodies requires further large scale studies.
Chilblain is an erythrocyanotic lesion of hands or feet, occurring after prolonged exposure to moderate to cold humidity. Most common in young and slim women, it can happen at every age, and relapses characteristically in autumn and winter. Clinical diversity is the rule, in frequent association with microvascular dysreactivity (mostly acrocyanosis). Chilblain is benign in most cases.
Bisalbuminemias are characterized on serum electrophoresis with a double band of albumin. They could be hereditary or acquired. This double band is composed of a protein with a normal mobility and with a protein with an other mobility which migrates in a more anodic or more cathodic position.
