[An atypical case of Horton's arteritis and associated polymyalgia rheumatica]. / Un caso atipico di arterite di Horton e polimialgia reumatica associata.

The authors report a case of Horton's arteritis and associated rheumatic polymyalgia, which was complicated from a diagnostic point of view by the atypical clinical and biohumoral conditions. Both the subjective and objective symptoms were relatively unclear compared to laboratory and instrumental findings which pointed strongly to an autoimmune disorder. The coexistence of biohumoral data of a cholestatic hepatitic type, not common to other pathologies, although reported in the literature, led to further diagnostic difficulties. Diagnosis was finally confirmed by temporal artery biopsy.

[A case of deep venous thrombosis and primary amyloidosis]. / Un caso di trombosi venosa profonda e amiloidosi primaria.

On the basis of a complicated case of primary amyloidosis observed at our medical division, the clinical criteria and the biochemical and physiological supports correlated to this disease are discussed. In particular, it has been tried to make a distinction between primary and secondary amyloidosis. In this study, the clinical case of a 67-year-old man with a history of monoclonal gammopathy of uncertain significance, dizziness and syncopal episodes personally observed for a deep venous thrombosis of the inferior right limb is described. Of particular interest is the discovery of unusual resistance to anticoagulant treatment.
