We present a 71-year-old man with primary amyloidosis characterized by several outstanding clinical features, namely hip involvement of a pseudotumoral appearance, periarticular osteolytic lesions and a pathological fracture. Kappa light chains in the synovial fluid were observed. The patient survived for 90 months without developing plasma cell dyscrasia, and with preservation of vital functions despite parenchymal involvement of multiple organs.
We present a case of a 22 year old male patient who developed a rabies encephalomyelitis with evolution of six weeks, treated first as a psychiatric disorder and later as an encephalitis. This case had the following important features; 1--A long time with the disease: usually the patients die into the first eight days after diagnosis; 2--The evident reactive gliosis; 3--Almost all the studied fields showed inclusion bodies in both supratentorial and infratentorial portions; 4--The hippocampus and spinal cord neurons had many or unique Negri bodies and some of those were giant; 5--Microglia proliferation and free acidophilus bodies. All those microscopic features mean a long evolution time that is rarely seen in this illness; in medical literature we found only ten long duration cases.
